MDR-20
Description:
MDR-20 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, overload, and over voltage protections, and DC OK relay contact with LED indicator for monitoring the PSU status.
