KM Series AC/DC Power Supplies

TDK-Lambda's KM family of encapsulated AC/DC power supplies is designed for medical and other OEM applications that require robust, encapsulated, lightweight, and compact power supplies. Single, dual, and triple output models are available with power ratings from 15 W to 40 W. KM power supplies operate with a wide input range of 90 V_AC to 264 V_AC and are available with combinations of output voltages, including 3.3 V, 5 V, 9 V, 12 V, 15 V, and 24 V (adjustable for special applications).

Featuring reinforced 4 kV_AC input to output isolations, these units meet the tough IEC60601-1 international safety standards for medical equipment, making them ideal for patient-connected medical and general-use applications. KMs are PCB-mount supplies designed for convection cooling and can be operated in temperatures from -25°C to +70°C. These sealed supplies resist dust, humidity, and harsh environments.

Standard features include high efficiency and MTBF as well as overcurrent, overvoltage, and overtemperature protection. Compliances include UL/IEC60601-1 Safety, Class II (no input ground wire needed), CE mark, EN55011 EMC, and RoHS.
