MDR-100 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.

Note	1. All parameters NOT specially mentioned are measured at 230VAC input, rated load, and 25°C of ambient temperature.
	2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1 uf & 47uf parallel capacitor.
	3. Tolerance: includes set up tolerance, line regulation, and load regulation.
	4. The power supply is considered a component that will be installed into the final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.
	5. The length of set-up time is measured at the first cold start. Turning ON/OFF the power supply may lead to an increase in the set-up time.
