NDR-240 switching power supply

NDR-240 series 240W Single Output Industrial DIN RAIL

NDR-240 is one economical slim 240W Din rail power supply series, adapt to be installed on TS-35/7.5 or TS-35/15 mounting rails. The body is designed 63mm 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.

NDR-240 is designed with metal housing that enhances the unit’s power dissipation. With working efficiency up to 90%, the entire series can operate at the ambient temperature between -20℃ and 70℃ 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 NDR-240 a very competitive power supply solution for industrial applications.

NOTE

 1.  All parameters NOT specially mentioned are measured at 230VAC 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.  Derating may be needed under low input voltage. Please check the derating curve for more details.

5.  lnstallation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. ln case the adjacent device is a heat source, 15mm clearance is recommended.

6.  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. For guidance on how to perform these EMC tests, please refer to “EMl testing of component power supplies.”

7.  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}.
