2.1 HOLD-UP TIME: 16ms(minimum)
Test Condition:1. Full load.
2.DCinput48V
2.2OVERSHOOT
Overshoot at turn on shall be less than 10% of the mominal output voltage.
1.0 PROTECTION:
If the power supply is latch into shutdown stage (When OCP,OVP or short protection is working), the power supply shall return to normal operation only after the fault has been removed and should reset PS-ON for a minimum of 1 second. Then,it will turn on again.
1.1 OVER VOLTAGE PROTECTION
SENSE LEVEL | OVER VOLTAGE |
+5V | 5.74Vmin | 7.0Vmax |
+12V | 13.4Vmin | 15.6Vmax |
+3.3V | 3.76Vmin | 4.3Vmax |
1.2 SHORT CIRCUIT PROTECTION
All output to GND.
4.1 REMOTE ON/OFF CONTROL
The power supply is turn on/off by TTL signal.
ACTIVE LOW | POWER SUPPLY TURN ON |
ACTIVE HIGH | POWER SUPPLY TURN OFF |
Remote On/Off Signal Characteristics
PS-ON | MIN | MAX |
Vil input low voltage | | 0.8V |
Lil, input low current ,Vin=0.4V | | -1.6mA |
Vih, input high voltage, Lin=-200uA | 2.0V | |
Vih open circuit, Lin=0 | | 5.25V |
4.2 AUXILIARY +5Vsb
This power supply is specifically equiped with an independent stand-by +5V output current, 2A max. This output will always provide +5V except when the AC line is cut-off.
4.3 AUTO RESTART
If the power supply’s output dropped out of the regulation which is caused by AC line Voltage, the power supply will automatically resumed normal operation only after the AC line voltage returns to the specified operating range.
5.0 ENVIRONMENT:
5.1 AMBIENT OPERATION TEMPERATURE 0℃to +50℃
5.2 AMBIENT OPERATION RELATIVE HUMIDITY 20% to 85%
5.3 AMBIENT STORAGE TEMPERATURE -40℃to +70℃
5.4 AMBIENT STORAGE RELATIVE HUMIDITY 10% to 95%
5.5 Mechanical Shock
operating : 1G peak in any axis.
Non-operation : 30G peak(half sine), 11ms any of orthogonal axis,in eigher direction.
5.6 Random Vibration
non-operation :Freqency sweep from 2 to 200 Hz and return at a rate of 1 octave per
minute with constant 1G acceleration.
Operating : 5 to 17Hz 2mm double amplitude displacement
18 to 199 Hz 0.73G acceleration.
200 to 500Hz 0.33G acceleration.
Freqency to be swept at a rate of 0.067 decades minute.
Dwell at resonant frequencies for 30 minutes. This test shall be
Conducted on all three axis of the power supply.
