Series Description
The serie includes dual output voltage choices individually isolated of 2 x 3.3 volts, 2 x 5 volts , 2 x 12 volts, 2 x 15 volts and 2 x 24 volts with easy combination. The total power is 8 W with one single channel able to provide up to 6.8 W.
All the modules are designed with LC network filter to minimize reflected input current ripple.
The modules include a soft-start, an input undervoltage lock-out, a permanent short circuit and overload protection and an output overvoltage limitation to ensure efficient module protections. The soft-start allows current limitation and eliminates inrush current during start-up. The short circuit protection completely protects the modules against short-circuits of any duration by a shut-down and restores to normal when the overload is removed.
The modules are potted with a bi-component thermal conductive compound to ensure optimum power dissipation under harsh environmental conditions.
