notes:
1 Output is fully isolated.
2 Output voltage is measured at output power connector.
3 1% minimum load is required to maintain the ripple and regulation.
4 Ripple and noise is measured from 10 KHz to 20 MHz at output terminals with a 0.1 μF ceramic capacitor and
a 22 μF electrolytic capacitor in parallel.
5 Maximum power must not exceed 135 W with convection cooling or 250 W for forced air. 5 and 9 V models maximum current listed.

conditions/description
Output voltage returns to within 1% in less than
2.5 mS for a 50% load change. Peak
transient does not exceed 5%.
Turn-on and turn-off overshoot shall not exceed
5% over nominal voltage.

At 120 VAC and 80% of rated maximim load

Adjustable with built-in trim pot.
When green (LED1) is on the power supply is operating normally.
Designated as PG on the CN1. This signal
goes high 100-500 mS after the output reaches regulation.
It goes low at least 1 mS before loss of regulation.

PROTECTION CIRCUIT
parameter
Input fuse

output over-voltage
over temp.
conditions/description
Built-in ac fuse. A blown fuse usually indicates permanent
damage to the power supply serviceable by factory only.
Current limiting starts at 110-140% of the rated output current in foldback mode and
recovers automatically.
Short circuit can be continuous. Recovers automatically upon removal of short.
Output is protected agaist overvoltage. Unit shuts down and latches
when voltage at output terminals exceeds 130%. AC input needs to be
reset to restart the power supply.
Power supply shuts down when temperature is in excess of 85 ºC. Auto recovery.
