Product Description

LED Single Output Switching Power Adaptor

LS series single output switching power supply is an electronic power supply that incorporates a switching regulator in order to be highly efficient. Like other types of power supplies.

LS series single output switching power supply transfer's power from a source like the electrical power grid to a load (e. G., a personal computer) while converting voltage and current characteristics.

LS series single output switching power supply is usually employed to efficiently provide a regulated output voltage, typically at a level different from the input voltage.


Feature

1. High efficiency, high reliability

2. AC input 110VAC, 220VAC select by switch

3.100% full load burn-in test

4. Protections: Short circuit/Over load

5. Cooling by free air convention

6. Fixed switching frequency at 37KHz


Note

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 centigrade degree of ambient temperature.

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

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