MEAN WELL Products
Description
A 250W dual output product with isolated outputs and PFC function designed to be used as an open frame or enclosed product. These compact 90~264V switchmode power supplies with active PFC are ideal for 1U installations. The isolated design between CH1 and CH2 can significantly prevent noise sourcing of motor action from entering control circuits and hence secure accurate operation of the end equipment. Accompany with the optional L-Bracket and cover to provide more alternatives to system configuration or solve mounting constraint issues. Other standard functions include remote control for CH1 and short circuit, over load, over voltage and over temperature protections.
