Description

MDR-20 Series is a slim line DIN rail 15W to 24W Class I switching power supply. Designed with a fully isolated plastic case to prevent user contact and the risk of shock. Featuring up to 84% efficiency this series can be cooled using only free air convection up to 70°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 the DC OK signal for monitoring the status of the PSU.
