WDR-120 switching power supply

WDR-120 series 120W Single Output Industrial DIN RAIL

WDR-120 is one economical slim 120W DlN rail power supply series, adapt to be installed on TS-35/7.5 or TS-35/15 mounting rails. The body is designed 40mm in width, which allows space saving inside the cabinets. The entire series adopts the full range AC input from 90VAC to 264VAC and conforms to BS EN/EN61000-3-2, the norm the European Union regulates for harmonic current.

EDR-120 is designed with metal housing that enhances the unit’s power dissipation. With working efficiency up to 88.5%, the entire series can operate at the ambient temperature between -20℃ and 60℃ under air convection. lt is equipped with constant current mode for over-load protection, fitting various inductive or capacitive applications. The complete protection functions and relevant certificates for industrial control apparatus (UL508, TUV BS EN/EN62368-1, and etc.} make EDR-120 a very competitive power supply solution for industrial applications.

 MTBF 1509.6K hrs min.       Telcordia SR-332 (Bellcore) ; 268.1K hrs min.       MIL-HDBK-217F (25℃)
DIMENSION 40*125.2*113.5mm (W*H*D)
PACKING 0.65Kg; 20pcs/14Kg/1.16CUFT
NOTE 1. All parameters NOT specially mentioned are measured at 400VAC input, rated load and 25℃ of ambient temperature.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3. Tolerance : includes set up tolerance, line regulation and load regulation.

4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.

5. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quick may lead to increase of the set up time.

6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft}.
