MAX. LOAD 18A 14A 14A 0.5A 0.5A 2.0A
MIN. LOAD 15A 0.8A 0.5A 0A 0A 0A
REGULATION ± 5% ± 5% ± 5% ± 10% ± 10% ± 5%
RIPPLE(mV) 50 120 50 120 100 50
2.1 HOLD-UP TIME: 17ms(minimun) Test Condition: 1. Full load 2. AC input 230V, 50Hz
2.2 LOAD TRANSIENT RESPONSE(STEP LOAD)
Step load changes of up to 50% of full load, while other loads remains constant within the rating. The load wave form shall be a square wave with the slope of the rise and fall at 1A/¦Ěsec and the frequency shall be from 10Hz to 1Khz.
The DC output voltage will stay within regulation during the step load changes.
2.3OVERSHOOT
Overshoot at turn on shall be less than 10% of the mominal output voltage.
3.1 PROTECTION
If the power supply is latch into shutdown stage (When OCP, OVP or short protcetion is working ), the power supply shall reurn to normal operation only after the fault has been removed and should reset PS-ON for a minimun of 1 second. Then, it will turn on again.
3.2 OVER CURRENT PROTECTION
Overload currents applied to each tested output rail will cause the output trip before they reach or exceed 400VA for testing purposes, the overload currents should be ramped at a minimun rate of 10A/s starting from full load.
3.3 SHORT CIRCUIT PROTECTION
All output to GND. |
