NGB250 Series Power Supplies

The NGB250 from SL POWER / Advanced Energy is a high-performance AC to DC external power supply family designed for next-generation medical and industrial applications. One of the most important aspects of medical power supplies is their safety approval. These models are approved to EN/IEC/UL60601-1, 3rd Edition with isolation levels and the latest EN/IEC/UL62368-1. This satisfies the 2xMOPP requirements. In addition, these products are designed to meet UL/EN/IEC60601-1-2, 4th Edition for EMC.

The NGB250 models will operate at the universal input range of 85 V_AC to 264 V_AC over the wide temperature range of -20°C to +80°C, delivering full rated output power up to +50°C and applicable output power derating at +80°C. The product family comes in the highest convection power density 2” x 4”. Standard output voltages are from 12 V_DC to 48 V_DC in both Class I and Class II input options.
