WEHO 40W single output DIN Rail switching power supply

MDR-40 is a slim line DIN rail Class I switching power supply. Designed with a fully isolated plastic case to prevent user contact and the risk of shock. Featuring up to 88% efficiency this series can be cooled using only free air convection up to 60°C which significantly increases the reliability and lifetime of the power supply. Other standard features include its low no load power consumption, to save energy, short circuit, over load and over voltage protections and DC OK relay contact with LED indicator for monitoring the PSU status.

we make transformers and power inductors by pure coppers all by ourselves,

weho Stocks each month: common models 150000 sets, quick delivery;
