Series Description
The total power is 20 W with one single channel able to provide up to 17 W.
All the modules are designed with LC network filters 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.
