NPT40-M Series

45—55 Watt Medical AC-DC Power Supplies

The NPT40-M series of open-frame AC-DC power supplies comprises three triple output models, covering a variety of standard voltages from 3.3 V to 24 Vdc. Each model accepts a universal input of 90 to 264 Vac or 127 to 300 Vdc. All models feature ITE and medical safety approvals. The series is 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.
