NPS20-M Series

25—40 Watt Medical AC-DC Power Supplies

The NPS20-M series of open-frame AC-DC power supplies features ITE and medical safety approvals. The series comprises five single output models, offering voltages of 5 V, 12 V, 15 V, 24 V or 48 Vdc. Each model has a typical full load efficiency of 87%. These power supplies are primarily intended for use in information technology equipment (ITE) and light industrial systems, as well as for equipment intended for non-patient contact and non-patient critical use in low power medical, dental and laboratory applications.
