PLP-20 Series - 20W Single Output PFC Open Frame LED Power Supply



PLP-20 Series are a range of single output open frame led lighting power supplies with single stage power factor correction and wide range 90~277VAC input voltage. The output current level can be fine tuned, through the potential-meter, between 75~100% of rated value increasing the flexibility of system design. Other standard features include short circuit, over load, over voltage and over temperature protections.
