Description
This DIN rail power supply comes from MEAN WELL's 40 W MDR-40 series and delivers 48 V DC at 0.83 A, together 39.8 W; the output voltage can be set between 48 and 56 V. It is supplied with 85-264 V AC or 120-370 V DC, at a typical efficiency of 88 %. It sits on TS-35/7.5 or TS-35/15 rails and cools itself without a fan by free convection. The operating range is -20 °C to +70 °C, with reduced load above the derating limit. It is protected against short circuit, overload and over-voltage; a DC OK relay contact (30 V/1 A) reports its state, and a power-on LED is added. Dimensions 40 x 90 x 100 mm, weight 0.3 kg. Approvals include UL508, EN 62368-1 and Class I, Div. 2 (T4); MEAN WELL grants a 3-year warranty. AETEK lists it for M30-011-30.
