Notes: 1. Maximum power must not exceed 135 W with convection cooling or 250 W for forced air. 5 and 9 V models maximum current listed.
2. 1% minimum load is required to maintain the ripple and regulation.
3. Ripple and noise is measured from 10 KHz to 20 MHz at output terminals with a 0.1 F ceramic capacitor and a 22 F electrolytic capacitor in parallel.
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 specifi cation
L = low leakage (contact factory)
