Features

  1. Cost effective 2. High efficiency 3. No derating without cover and horizontal mounting 4. Over voltage protection General Description ER-series is an open frame, low cost switcher with high efficiency. 65 different models are available from low to medium power. Low power modules use a simple RCC circuit while higher power supplies employ a forward converter. Options Case cover (add suffix “-P”) “-P” model dimension is same as “without cover” model
