Power Supply
45W DIN-Rail 24 VDC Power Supply
Overview
The DR series of power supplies provides a reliable DC power source for any industrial control system.
Combining rugged, compact enclosures, incorporating all international standards and approvals, and offering short
circuit, over load, over voltage, and over temperature protection, the DR series makes your power supply choice a
simple one. These high quality power supplies have passed a 100% full load burn-in test, and are UL/CUL listed,
TUV/CB certified, and CE marked. Models are available with output ratings from 45W to 120W, with 24 VDC output.
Customers can choose from a full range of input voltages (85 to 264 VAC and 120 to 370 VDC compatible) making the
DR series unbeatable.
