Phihong AA240U-59FKEA-R # 100 Vac and 230 Vac validation record One source assembly, sample s_sample1. Tested 15 October 2026. Record PHI-AC-20261015 | Revision 1.0 | Issued 15 October 2026. | Recorded result | 100 Vac | 230 Vac | | --- | --- | --- | | Independent test cases | 37 / 37 PASS | 37 / 37 PASS | | Steady / helper readings | 2,568 / 31 | 2,568 / 31 | | 5 V preflights / PD captures | 37 / 37 | 37 / 37 | | Voltage / current out-of-band readings | 0 / 0 | 0 / 0 | | Maximum absolute V / A error | 0.719 V / 0.004 A | 0.715 V / 0.005 A | All 74 cases completed with measured voltage and load current inside the configured screening limits. Both inputs completed Fixed and AVS 48 V / 5 A current sweeps and 60 s holds, the AVS 36-48-36 V / 5 A sweep, both PPS APDO load sweeps, and six light-load returns to 5 V. No output collapse was detected in the recorded steady samples. Test conditions | Item | Recorded condition | | --- | --- | | Source / lead | Phihong AA240U-59FKEA-R, s_sample1 / captive 1.0 m | | Connection | SRC - integral captive lead - CY4500-EPR - ASD-PD31; CC2 | | AC input metadata | 100 Vac / 50 Hz; 230 Vac / 50 Hz | | Instrument / controller | ASD-PD31 / v5.8.9 | | Measurement point | ASD-PD31 input, including captive lead, analyzer and connection losses | Acquisition windows (JST, UTC+09:00): 100 Vac 11:17-12:33; 230 Vac 12:38-13:55, 15 October 2026. AC values are configured metadata; no independent AC voltage measurement is included. PASS here means that the specified sequence and measurement checks completed. This one-unit record does not establish production variation, continuous 240 W endurance, USB-IF conformance or electrical safety certification. Source temperature, AC input power and efficiency were not measured. --- # Capabilities and coverage Both discovery snapshots contain the same 10 visible objects. Object 7 is absent from the decoded table; no Object 7 capability was assumed. The two PPS APDOs share a voltage range but have different advertised current limits and were selected separately. | Object | Type | V | A | Raw PDO | | --- | --- | --- | --- | --- | | 1 | Fixed | 5 | 3 | 0x0A81912C | | 2 | Fixed | 9 | 3 | 0x0002D12C | | 3 | Fixed | 15 | 3 | 0x0004B12C | | 4 | Fixed | 20 | 5 | 0x000641F4 | | 5 | PPS | 5-21 | 3 | 0xC1A4323C | | 6 | PPS | 5-21 | 5 | 0xC1A43264 | | 8 | Fixed | 28 | 5 | 0x0008C1F4 | | 9 | Fixed | 36 | 5 | 0x000B41F4 | | 10 | Fixed | 48 | 5 | 0x000F01F4 | | 11 | EPR AVS | 15-48 | 5 | 0xD3C096F0 | | Test group | Cases / AC | Evidence IDs | | --- | --- | --- | | Fixed baseline at 1 A | 7 | A01-A07 / B01-B07 | | PPS / AVS baseline at 1 A | 3 | A08-A10 / B08-B10 | | Fixed current round trips | 7 | A11-A17 / B11-B17 | | PPS / AVS current round trips | 9 | A18-A26 / B18-B26 | | AVS upper voltage round trip | 1 | A27 / B27 | | 60 s holds | 4 | A28-A31 / B28-B31 | | Light-load returns to 5 V | 6 | A32-A37 / B32-B37 | Current sweeps use 0.2 A steps from 0.2 A to the bounded PDO limit and back, with three readings per point and a single turnaround point. Fixed 5/9/15 V and PPS Object 5 reach 3 A; the other tested current sweeps reach 5 A. Voltage baselines use 1 V steps and three readings per point. No discovered capability was skipped. Screening checks: |measured V - target V| <= 1.0 V and |measured A - load target A| <= max(0.05 A, 2%). These are instrument screening settings, not PD specification limits. Each case starts with a measured 5 V / 0.1 A preflight and ends with acknowledged LOAD_OFF plus current <= 0.05 A. ASD versions, both inputs: type 05.54; power FW 09.18 / HW 05.01; protocol FW 04.77 / HW 04.00; display FW 01.74 / HW 00.02. Full query records accompany the evidence. --- # Fixed PDO load behavior | Maximum load point | 100 Vac | 230 Vac | Evidence | | --- | --- | --- | --- | | O1 / 5 V / 3 A | 4.787-4.790 V; 3.000 A | 4.785-4.788 V; 3.000 A | A11 / B11 | | O2 / 9 V / 3 A | 8.630-8.632 V; 3.000 A | 8.629-8.631 V; 3.000 A | A12 / B12 | | O3 / 15 V / 3 A | 14.624-14.627 V; 3.000 A | 14.625-14.627 V; 3.000 A | A13 / B13 | | O4 / 20 V / 5 A | 19.361-19.363 V; 5.000 A | 19.354-19.360 V; 5.000 A | A14 / B14 | | O8 / 28 V / 5 A | 27.332-27.335 V; 5.000 A | 27.334-27.338 V; 5.000 A | A15 / B15 | | O9 / 36 V / 5 A | 35.312-35.317 V; 5.000 A | 35.306-35.311 V; 5.000-5.001 A | A16 / B16 | | O10 / 48 V / 5 A | 47.304-47.309 V; 5.000 A | 47.303-47.306 V; 5.000 A | A17 / B17 | ![fixed_48v.png](figures/fixed_48v.png) Every tested Fixed PDO completed its outbound and return current points at both inputs. The table shows the three readings at the peak current. Fixed 48 V / 5 A was maintained during the sweep and the separate 60 s hold. Lower ASD voltage at high current includes the complete measurement path and is not a direct measurement of the source connector voltage. No series-resistance correction was applied to these results. Voltage ranges are the recorded ADC minima and maxima, not confidence intervals or calibrated uncertainty bounds. --- # PPS APDO load behavior | Maximum load point | 100 Vac | 230 Vac | Evidence | | --- | --- | --- | --- | | O5 / 5 V / 3 A | 4.624-4.627 V; 3.000 A | 4.619-4.623 V; 3.000 A | A18 / B18 | | O5 / 16 V / 3 A | 15.612-15.615 V; 3.000 A | 15.613-15.615 V; 3.000 A | A19 / B19 | | O5 / 21 V / 3 A | 20.596-20.597 V; 3.000 A | 20.598-20.599 V; 3.000 A | A20 / B20 | | O6 / 5 V / 5 A | 4.372-4.380 V; 4.999-5.000 A | 4.363-4.378 V; 5.000 A | A21 / B21 | | O6 / 16 V / 5 A | 15.359-15.369 V; 5.000 A | 15.359-15.360 V; 5.000 A | A22 / B22 | | O6 / 21 V / 5 A | 20.343-20.350 V; 5.000 A | 20.347-20.354 V; 5.000 A | A23 / B23 | ![pps_current.png](figures/pps_current.png) PPS Object 5 completed 5, 16 and 21 V current round trips through its 3 A limit. PPS Object 6 completed the same voltage points through 5 A. The 1 A baseline covered all integer voltages from 5 to 21 V for each object. The separate 21 V holds maintained 3 A and 5 A respectively for a programmed 60 s. Current tracking was checked against the electronic-load target, independently of PD request current. The packet captures retain the actual Request words, so contract behavior can be reviewed without treating CLI request parameters as proof of transmitted RDO values. --- # EPR AVS and high-voltage sweep | Maximum load point | 100 Vac | 230 Vac | Evidence | | --- | --- | --- | --- | | AVS O11 / 15 V / 5 A | 14.373-14.375 V; 5.000 A | 14.374-14.379 V; 5.000 A | A24 / B24 | | AVS O11 / 16 V / 5 A | 15.370-15.378 V; 5.000 A | 15.376-15.379 V; 5.000 A | A25 / B25 | | AVS O11 / 48 V / 5 A | 47.295-47.301 V; 5.000 A | 47.301-47.303 V; 5.000 A | A26 / B26 | ![avs_high.png](figures/avs_high.png) The AVS baseline covered 15-48 V at 1 A. The high-load sweep used 36-48-36 V at 5 A in 1 V steps, with 25 voltage points and 75 steady readings per input. Each point had a configured minimum 5 s dwell after the initial bounded load ramp. The 48 V turnaround was sampled once. | Run | Measured current | Max. |V error| | Ripple readings | | --- | --- | --- | --- | | 100 Vac / A27 | 5.000 A | 0.711 V | 141-185 mV | | 230 Vac / B27 | 4.999-5.001 A | 0.713 V | 135-167 mV | Ripple values are ASD-PD31 telemetry only. Measurement bandwidth and a calibrated oscilloscope ripple setup are not established in this record. These readings support comparison within this setup and are not a ripple compliance verdict. --- # Programmed 60-second holds | Evidence / input | Setpoint | V | A | Mean W | Max mV | | --- | --- | --- | --- | --- | --- | | A28 / 100 Vac | FIXED O10; 48 V / 5 A | 47.281-47.305 | 4.999-5.001 | 236.462 | 187 | | B28 / 230 Vac | FIXED O10; 48 V / 5 A | 47.285-47.311 | 4.999-5.000 | 236.479 | 168 | | A29 / 100 Vac | PPS O5; 21 V / 3 A | 20.591-20.594 | 3.000 | 61.777 | 153 | | B29 / 230 Vac | PPS O5; 21 V / 3 A | 20.592-20.597 | 2.999-3.000 | 61.781 | 163 | | A30 / 100 Vac | PPS O6; 21 V / 5 A | 20.329-20.350 | 4.999-5.001 | 101.697 | 158 | | B30 / 230 Vac | PPS O6; 21 V / 5 A | 20.330-20.351 | 5.000-5.001 | 101.707 | 161 | | A31 / 100 Vac | AVS O11; 48 V / 5 A | 47.284-47.305 | 5.000 | 236.465 | 200 | | B31 / 230 Vac | AVS O11; 48 V / 5 A | 47.287-47.309 | 5.000-5.001 | 236.483 | 179 | ![holds_48v.png](figures/holds_48v.png) Each hold contains 60 steady readings at approximately one-second intervals. The first-to-last recorded steady span is about 59.0 s within the programmed 60 s hold, followed by LOAD_OFF. The table reports ASD input power; the nominal 48 V x 5 A request is 240 W, while delivered power at this measurement point includes path losses. Temperature fields are internal ASD-PD31 telemetry affected by its cooling fan. They are retained in the original evidence but excluded from source temperature assessment. These short holds do not demonstrate thermal equilibrium or long-term endurance. --- # Light-load returns to 5 V | Transition | 100 Vac | 230 Vac | Evidence | | --- | --- | --- | --- | | 48 -> 5 V / 0.1 A | 5.141-5.143 V; 0.100 A | 5.144-5.145 V; 0.100 A | A32 / B32 | | 36 -> 5 V / 0.1 A | 5.141-5.145 V; 0.100 A | 5.143-5.146 V; 0.100 A | A33 / B33 | | 28 -> 5 V / 0.1 A | 5.141-5.144 V; 0.100 A | 5.144-5.145 V; 0.100 A | A34 / B34 | | 20 -> 5 V / 0.1 A | 5.142-5.145 V; 0.100 A | 5.145-5.146 V; 0.100 A | A35 / B35 | | 9 -> 5 V / 0.1 A | 5.142-5.144 V; 0.100 A | 5.144-5.145 V; 0.100 A | A36 / B36 | | 15 -> 5 V / 0.1 A | 5.142 V; 0.100 A | 5.144-5.145 V; 0.100 A | A37 / B37 | Each independent case applies the initial Fixed PDO at 0.1 A and then requests Fixed 5 V at the same load. Three ADC readings per endpoint use a configured 2 s delay. All six starting voltages returned to approximately 5.14 V at approximately 0.1 A for both inputs, including 15 V to 5 V. PD evidence and interpretation For all 12 light-load return cases, the final captured Fixed 5 V Request was followed by Accept and PS_RDY. For the 15 V to 5 V examples [A37, B37], the final Request RDO is 0x1044B12C at both inputs. Packet row references and raw values are in analysis/transition_packet_events.csv. This records the observed exchange without assigning a timing verdict. CY4500 packet CSVs accompany every case and the initial discovery run. The captures preserve Source Capabilities, Request/EPR Request, Accept and PS_RDY messages. They are provided as packet evidence; no automated USB-IF timing or waveform conformance score is assigned. Endpoint ADC sampling cannot exclude brief undershoot, overshoot or transient interruptions between samples. Input comparison and scope No case changed PASS/FAIL outcome between the two inputs. Mean ASD voltage in the Fixed 48 V / 5 A hold changed by +0.004 V (230 Vac minus 100 Vac). The tests used the same source assembly sequentially; the comparison does not isolate warm-up or conditioning effects. Ambient temperature and independent AC voltage metrology were not logged. The recorded results support successful initial functional screening of this sample under the listed setup. Additional units, longer endurance holds and dedicated transient/thermal measurements would be needed to extend that conclusion. --- # Evidence index and data definitions Axx identifies 100 Vac; Bxx identifies 230 Vac.

The 74 preflights add 148 readings. Discovery files and PD voltage packets are separate and are not counted as steady ASD results. analysis_phase is an added analysis field; original mode values are retained. No literal steady mode is required: precheck/ramp modes are helpers; the steady mode allow-list is documented in README.md.
