DP40-M Medical Series

40 Watt AC-DC Power Adapters (Medically Approved)

The DP40-M series of freestanding external 40 watt AC-DC power adapters carries both medical and safety approvals. These adapters provide a very flexible, pre-approved power solution for a wide variety of portable and desktop applications, including medical, instrumentation, telecommunications, computer peripheral and test and measurement systems. The adapters are available in both Class I and Class II configurations with a 2-pin or 3-pin AC input connector.

There is a choice of 12 models, covering output voltages from 9 to 48 Vdc and output currents up to 4.44 amps. All these adapters accept a wide 90—264 Vac input and can also operate from a 127—300 Vdc supply. They meet Energy Star Efficiency Level V criteria and have a no-load power consumption of less than 300 mW.
