Features

  1. Open Frame 2. Cost Effective 3. High Efficiency 4. No derating without cover and horizontal mounting 5. Input 170-264Vac 6. EMI : complies with FCC/A, FCC/B for ERD & ERE 7. Over voltage protection Cover(add suffix “-P”) **”-P” model dimension is same as “without cover” model General Description “ER”-Series AC/DC Switching power supplies are open frame, low cost with high efficiency. 65 different models are available from low to medium power. A low power modules use a simple RCC circuit while high power supplies employ a forward converter.
