Description
Details
The MDR DIN rail power supply family is designed for compact industrial control cabinets, CNC systems, automation panels and auxiliary DC circuits. In addition to the existing MDR-60 variants, this product now includes the compact MDR-20 series with 5V, 12V and 24V DC outputs. MDR-20 units accept 85–264VAC or 120–370VDC input, mount on standard TS35/7.5 or TS35/15 DIN rail and use free-air convection cooling.
The MDR-20 series combines adjustable DC output, LED power indication, short-circuit, overload and over-voltage protection, plus a built-in DC OK active signal. The 22.5mm housing width makes these models suitable where panel space is limited.

| NOTE | 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. 5. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time. | ||||
