MEAN WELL MDR-60 series: Industrial DIN Rail Power Supply - MDR-60-48

Description

MEAN WELL MDR-60-48 is a single-output industrial DIN rail power supply rated at 48 V DC, 1.25 A and 60 W. It accepts 85–264 VAC or 120–370 VDC, uses free-air convection cooling and provides adjustable output, an LED indicator and a DC OK relay contact in a 40 mm-wide enclosure.

Model and Output

Complete model / catalogue MDR-60-48; MDR-60 catalogue revision 2025-07-25. The final code denotes the nominal 48 V output.
Rated DC output 48 V / 1.25 A / 60 W; current range 0–1.25 A.
Output adjustment 48–56 V using +V ADJ. Observe the rated output-current and power limits when adjusting voltage.
Ripple and noise 200 mVp-p maximum; measured at 20 MHz bandwidth with a 12-inch twisted pair terminated by parallel 0.1 µF and 47 µF capacitors.
Voltage tolerance ±1%, including setup tolerance, line regulation and load regulation.
Line / load regulation ±1% / ±1%, respectively.
Typical efficiency 87% at the default 230 VAC input, rated-load and 25°C ambient test conditions.

Use the model-specific 60 W rating together with its input-voltage and ambient-temperature limits; the series name is not a uniform power rating for every output voltage.

Input and Timing

AC / DC input 85–264 VAC or 120–370 VDC; AC frequency 47–63 Hz.
Typical AC current 1.8 A at 115 VAC; 1 A at 230 VAC.
Typical cold-start inrush 30 A at 115 VAC; 60 A at 230 VAC.
Leakage current Less than 1 mA at 240 VAC.
Setup / rise time 500 / 30 ms at both 230 VAC and 115 VAC, at full load.
Typical hold-up time 50 ms at 230 VAC; 20 ms at 115 VAC, at full load.
No-load power consumption Less than 0.75 W.

Setup time is measured at the first cold start; repeated power ON/OFF switching may increase it. Unless otherwise stated, specifications use 230 VAC input, rated load and 25°C ambient.

Protection and DC OK Relay

Short circuit / overload 105–150% of rated output power; constant-current limiting, with automatic recovery after the fault is removed.
Overvoltage 57.6–64.8 V; output shutdown, with re-powering required for recovery.
DC OK contact states Closed: PSU turns on / DC OK. Open: PSU turns off / DC Fail.
Relay contact maximum 30 V / 1 A with a resistive load. Use the two terminals marked DC OK as the relay contact pair.
Front indication / control DC OK LED indication and +V ADJ output-voltage adjustment are shown on the front drawing.
Switching frequency 60 kHz, as labelled in the block diagram.

The DC OK connection is a relay contact for monitoring; the contact rating is not an auxiliary power-output rating. Overload thresholds describe protective operation, not permission to exceed the continuous output rating.

Cooling and Operating Limits

Cooling / orientation Free-air convection; the published ambient-temperature curve is for vertical mounting.
Temperature derating Operating range −20 to +70°C, subject to derating. This model permits 100% load through +55°C, then decreases linearly to 60% load at +70°C.
Input-voltage derating At 60 Hz AC, the curve shows 80% load at 85 VAC and 100% at 100 VAC; the full-load plateau continues to 264 VAC. Apply this with the temperature derating limit.
Working humidity 20–90% RH, non-condensing.
Storage temperature / humidity −40 to +85°C; 10–95% RH.
Temperature coefficient ±0.03%/°C over 0–50°C.
Vibration Component: 10–500 Hz, 2G, 10 min/cycle, 60 min on each X, Y and Z axis. Mounting: compliance with IEC60068-2-6.

For this fanless design, the catalogue specifies an additional ambient-temperature derating of 3.5°C per 1000 m above 2000 m. This footnote does not state a maximum approved installation altitude.

Safety, Isolation and EMC

Listed safety standards UL508, UL62368-1, TUV BS EN/EN62368-1, EAC TP TC004, BSMI CNS14336-1 and AS/NZS60950.1.
Hazardous-location classification Class I, Division 2, Groups A, B, C and D, temperature code T4, as listed in the manufacturer’s specification. Follow the applicable product marking and installation requirements.
BIS approval scope The 48 V model is excluded from the catalogue’s BIS IS13252 / IEC60950-1 approval listing.
Withstand voltage Input–output: 3 kVAC; input–FG: 2 kVAC; output–FG: 0.5 kVAC.
Isolation resistance Greater than 100 MΩ for input–output, input–FG and output–FG, tested at 500 VDC, 25°C and 70% RH.
EMC emission BS EN/EN55032 (CISPR32), BS EN/EN61204-3 Class B, BS EN/EN61000-3-2 and -3, EAC TP TC020, and CNS13438 Class B.
EMC immunity BS EN/EN61000-4-2, -3, -4, -5, -6, -8 and -11; BS EN/EN55035, BS EN/EN61000-6-2, BS EN/EN61204-3, heavy-industry level; EAC TP TC020.

This supply is a component for installation in final equipment. The completed equipment must be checked again for applicable EMC compliance.

Dimensions, Terminals and Installation

Body size 40 × 90 × 100 mm (W × H × D); case 962A; drawing tolerance ±1 mm.
DIN rail compatibility TS-35/7.5 or TS-35/15; the rail drawing marks a 35 mm width.
Upper terminals, front view From left to right: +V, +V, −V, −V, followed by the two DC OK relay-contact terminals. Adjacent terminal centres are shown 5 mm apart.
Lower terminals, front view From left to right: FG (protective earth), AC/N and AC/L. Adjacent terminal centres are shown 7.5 mm apart.
Wiring and fastening Connect FG to protective earth and follow the actual terminal markings. Use the supplied unit’s installation instructions for wire size and terminal torque; these catalogue pages do not specify those numerical limits.

Refer to PDF page 8 for the mounting latch, terminal layout and clearances. A compatible DIN rail is an installation item, not a statement that a rail is supplied. These MDR-60 pages do not give a separately orderable MEAN WELL bracket, cover, connector or cable accessory model.

Weight and Manufacturer Information

Single-unit catalogue packing reference 287 g per unit, from the PACKING entry on PDF page 7: 287 g; 42 pcs / 13.05 kg / 0.82 CUFT. This is a catalogue packing reference, not a measured net or shipping weight.
MTBF reference 2355.2 K hours minimum, Telcordia SR-332 (Bellcore); 489.9 K hours minimum, MIL-HDBK-217F at 25°C. These calculated reliability references are not a guaranteed operating life.
Production test The manufacturer lists a 100% full-load burn-in test.
Warranty statement The manufacturer’s catalogue lists a three-year warranty, subject to its applicable terms.
