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.

Input/Output connector:
“blank” = Terminal block input / Terminal block output
1 = Molex input / Molex output
2 = Molex input / Terminal block output
3 = Terminal block input / Molex output
Low leakage option:
“blank” = standard specification
L = low leakage (contact factory)
