Product Overview

The MDR-10 series is MEAN WELL's ultra-slim 10W DIN rail industrial power supply with a 22.5mm width -- the narrowest DIN rail supply in MEAN WELL's portfolio. Designed for space-constrained control panels, it features a built-in active DC OK signal output that sources current to drive external LEDs, relays, or PLC inputs for real-time power status monitoring -- a capability absent from entry-level HDR and NDR models.

The MDR-10 accepts universal 85~264Vac input (120~370Vdc) with 0.33A/115V, 0.21A/230V AC current and 35A/70A cold-start inrush. Four voltages: 5V (2A), 12V (0.84A), 15V (0.67A), and 24V (0.42A) -- all delivering 10W. Efficiency ranges from 77% at 5V to 84% at 24V. The 120ms hold-up time at 230Vac is exceptionally long for a 10W supply, providing superior brownout ride-through. No-load consumption is <0.75W.

Protection is straightforward: >105% OLP in hiccup mode with auto-recovery, OVP with output shutdown requiring a restart, and short-circuit protection. The MDR-10 uses a metal chassis with FG terminal (unlike the plastic Class II HDR series) -- it requires protective earth. Isolation is 3KVac I/P-O/P, 2KVac I/P-FG, 0.5KVac O/P-FG. EMC compliance is Class B with light industrial immunity per EN61000-6-1.

The MDR-10 holds UL508, TUV BS EN/EN62368-1, EAC, BSMI, AS/NZS 62368.1, and BIS IS13252 certifications -- fully certified for global industrial deployment. At 22.5x90x100mm and only 170g, with 72 units per carton, it is the most compact DIN rail supply for distributed 10W control power. 3-year warranty with 100% full-load burn-in test.

Frequently Asked Questions

How do I use the DC OK signal?

The MDR-10's DC OK pin is an active sourcing output -- when the output voltage is healthy, it sources current at a voltage proportional to the output. You can use it three ways: (a) LED indicator -- connect DC OK to V- through a resistor; (b) Relay -- drives a small relay coil for dry-contact status signaling to a PLC/SCADA input; (c) PLC digital input -- wire directly to a 24V PLC input for real-time power monitoring. Maximum current varies by model: 50mA (5V), 40mA (12V/15V), 20mA (24V).

Does MDR-10 require an earth/ground connection?

Yes. Unlike the HDR series (Class II plastic, no FG), MDR-10 uses a metal chassis with an FG (Frame Ground) terminal that must be connected to protective earth. The three isolation ratings (I/P-O/P 3KVac, I/P-FG 2KVac, O/P-FG 0.5KVac) depend on proper earthing. If you need an earth-free solution, consider the HDR-15 or HDR-30 plastic-shell series instead.

Why is 120ms hold-up important for a 10W supply?

120ms at 230Vac is 7.5x longer than typical 10W supplies (which average 16ms). This means the MDR-10 can ride through 6+ cycles of power interruption at 50Hz. In industrial panels where a momentary brownout could cause a PLC to reboot or a safety relay to drop out, this extended hold-up keeps 10W control circuits alive through transfer switch events, generator start-up, and grid transients that would crash a standard supply.

How does MDR-10 compare to HDR-15?

MDR-10 (10W, 22.5mm, metal+FG, DC OK, 120ms hold-up) vs HDR-15 (15W, 17.5mm, Class II plastic, LPS, 30ms hold-up). Choose MDR-10 when you need DC OK monitoring, long hold-up, BIS certification, and can earth the chassis. Choose HDR-15 when you need 15W, LPS safety, earth-free Class II, or the narrowest 17.5mm width. They serve different niches in the 10-15W DIN rail space.
