0 z1 w; I% v' X. ]* d; |1.2.2.1 –MAXIMUM OUTPUT VOLTAGE, CURRENT, AND VOLT-AMPERE MEASUREMENT TEST METHOD A sample of power supply, Model ______was connected to _240_[Vac,_60_Hz][Vdc]. The following parameters for each output were measured: A: The maximum peak output voltage (V) under any resistive loading condition. B: The maximum rms output current (A) under any resistive loading condition [after][at] 60 seconds. C: The maximum volt-Ampere (VA) under any resistive loading condition [after][at] 60 seconds. RESULTS | Output tested | Maximum | HAZ/EL[Yes][No] | (V) | (A) | (VA) | 1. | | | | | | 2. | | | | | | 3. | | | | | | 4. | | | | | | Comments: |
8 w* i1 N/ Y7 Y }! ~2 Q9 WNOTES TO LAB: 1. Output which exceeds 240VA is considered to be hazardous energy level (HAZ/EL). 2. Indicate the load used for each test condition. NOTES TO ENGINEER: 1. Indicating loading condition (s) for output (s) not under test. 2. These measurements are to be taken for QQGQ2 Guiducard information. Addition testing in the end-use application may be necessary to determine if an energy hazard exists.
