Series Deep-Dive

DR Series – The Workhorse Entry-Level Solution

The DR series is LEYU's most accessible DIN rail power supply line, covering 15W to 120W with 5V, 12V, 24V, and 48V output options. These units feature universal AC input (85–264VAC), built-in protections (short circuit/overload/overvoltage), and free-air convection cooling.

Applications: LED lighting drivers, small control panels, basic automation, test equipment.

MOQ: 1 piece | Lead Time: 1–7 working days

MDR Series – Ultra-Slim for Tight Spaces

When every millimeter counts, the MDR series delivers. With widths as slim as 55mm (or narrower for lower power models), these units are designed for TS-35/7.5 or TS-35/15 DIN rails. The MDR series features universal AC input, natural convection cooling, and comprehensive protections.

Applications: Compact control cabinets, building automation, IoT gateway enclosures.

EDR Series – Heavy-Duty Industrial Power

For demanding industrial environments requiring higher power output, the EDR series delivers 75W to 480W with 12V, 24V, 36V, and 48V options. These units are built to withstand harsh conditions with robust thermal management and full-load burn-in testing.

Applications: Factory automation, heavy machinery, conveyor systems, industrial robotics.

NDR Series – German Standard Compliance

The NDR series is an economical slim-profile line designed to meet German industrial standards (DIN EN/BSEN/EN61000-3-2) for harmonic current specifications. With a wide input range (90–264VAC) and slim width (as narrow as 32mm for certain models), NDR series is ideal for applications requiring EU harmonic compliance.

Applications: European market projects, harmonic-sensitive installations, industrial control systems requiring CE compliance.

HDR Series – Economical Ultra-Slim

The HDR series offers one of the slimmest footprints in LEYU's lineup—with 15W models as narrow as 17.5mm (1SU). These economical units feature universal AC input (85–264VAC, 277VAC operational) and full harmonic compliance.

Applications: Space-critical installations, building management systems, distributed control architectures.

WDR Series – Wide-Input Versatility

The WDR-120 series delivers 120W of regulated output in an ultra-slim 40mm DIN rail housing. With wide input range capability and comprehensive protection features, it's engineered for industrial control systems, factory automation, and semiconductor fabrication equipment.

ZDR5 Series – Next-Generation High Efficiency

The ZDR5 series represents LEYU's latest advancement in DIN rail power supply technology. With efficiency exceeding 88%, these units significantly reduce heat generation and energy costs. Unlike traditional power supplies, the ZDR5 supports both AC and DC input (100–240VAC or 127–370VDC), offering exceptional flexibility for different grid standards or backup battery systems.

Applications: Factory automation, PLC systems, panel building, industrial control systems.
