YUEQING YINGLANG IMP&EXP CO.,LTD.

The new YINGLANG 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 8 W, is then available at the output.

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

The 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 illuminated switches. Thanks to its versatility, however, it is suitable for supplying power to a wide range of indoor applications.

The universal switch power supply adopts power semiconductor as the switching element. The output voltage is adjusted by making and breaking the switch periodically and control the time ratio of off to on of the switch elements. Meanwhile, it has over-current and over-voltage protection.

It has the advantages of small output wave, high efficiency, small volume, light weight, and elegant appearance.
