New power supply unit

Louise Smyth

The new Schurter PSUP switching power supply unit processes DC (127-370 VDC) or AC (90-264 VAC, 47-63 Hz) from the input side. A constant 24 VDC, with a power of 8W, is then available at the output.

The housing of the PSUP is completely insulated and is rated IP42 for indoor use. The operating temperatures may vary between -30 and +70°C. The particularly compact dimensions, along with the double-sided mounting lugs and wire leads, provide for extremely simple assembly.

The PSUP 24 VDC is protected against short circuit, overload and overvoltage. The power supply is UL8750, CSA CS22.2 no. 250.0-08 approved. It complies with EN60950-1, EN61347-1, EN61347-2-13, as well as EMC emission standards EN55022, EN61000-3-2 and EN61000-3-3.

The new switching power supply unit was initially developed to support Schurter's Metal Line illuminated switches. As it is versatile however, it is suitable for supplying power to a wide range of indoor applications.
