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.

PROTECTION CIRCUIT

parameter

Input fuse

conditions/description

Built-in ac fuse. A blown fuse usually indicates permanent

damage to the power supply serviceable by factory only.

overload

Current limiting starts at 110-140% of the rated output current in foldback mode and

recovers automatically.

short circuit

output over-voltage

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.

over temp.

Power supply shuts down when temperature is in excess of 85 ºC. Auto recovery.
