WMMPU12 Series

WMMPU12A-108

The WMMPU12 series of Class II medical AC/DC wall mount power supplies provides up to 12 Watts of continuous output power. This series consists of single output models from 5VDC to 27VDC with a 90~264VAC input voltage range. These supplies also have over voltage, over load, and over temperature protection. This series has UL/cUL 60601-1: 2nd Edition (US plug type only) and TUV/T-mark EN60601-1: 2nd Edition (UK and EU plug types only) medical approvals. All units are RoHS and Energy Star 2.0, Efficiency Level V compliant. These units also meet new CE requirements and are well suited for use in blood pressure measurement equipment, frequency therapy devices, and dental curing light applications. The WMMPU12 series has three types of plugs available: US (A Type), UK (B Type), and EU (C Type). Optional output connectors are also available for this series. Please call factory for ordering details.

NOTES

  1. Over Temperature Protection: Thermal shutdown by junction temperature controller; the adapter will automatically recover when the fault condition is removed.

  2. Models WMMPU12-102~103 needs to use AWG#18/6FT output cable in order to meet the total regulation specified.
    Models WMMPU12-104~108 needs to use AWG#20/6FT output cable in order to meet the total regulation specified.
    The regulation and efficiency will change if a different output cable is used.

  3. Optional output connectors are available. Please call factory for ordering details.
