max load 12A 12A 7A 0.6A 2A
Full load 9A 9A 5A 0.5A 1.5A
Min load 1.0A 0.5A 0.5A 0.1A 0.1A
Regulation ±5% ±5% ±5% ±10% ±5%
Ripple 50mV 120mV 50mV 200mV 50mV
Noise 100mV 240mV 100mV 300mV 100mV
Power supply works continuously, the DC output total power with no more than 180W, +3.3V and +5V sum of output power maximum 90 W.
A 0.1uF ceramic disk capacitor & 10uF electrolytic (low ESR) capacitor should be put across the output terminals during ripple & noise measure. The oscilloscope bandwidth set at 20MHz with co-axial probe.
Regulation load must within 30% to 70% of maximum load.
AMBIENT TEMPERATURE 25
5. Protection
NOTE: due to overpower, overvoltage, under voltage, short-circuit protection movement, the power locked in shut off condition, only when these reasons remove, remote control switch at least 1 second reduction (or at least reset shut the power supply after 10 seconds), power supply can restart.
5.1 Short-circuit protection: the power supply will be automatic protection and close the output no matter which output terminal short circuit.
5.2 OVER LOAD PROTECTION
120-160% of maximum power
5.3 SHORT CIRCUIT PROTECTION
All output to ground
6. Time SEQ Test
6.1 POWER GOOD signal delay time (T3): 100ms ≤T3≤500ms
6.2 POWER GOOD signal rise time (T4): T4≤10ms
6.3 Hold-up Time (T5): T5≥16ms
6.4 POWER FALL signal delay time (T6): T6≥1ms
7. Remote Switch Control
7.1 DC output (except for +5Vsb) can be controlled by logic circuit
7.2 Logic circuit controls power supply on and off
