The LEYU HDR-60 series is a flagship ultra-slim 60W industrial DIN rail power supply, specifically engineered for installation on TS-35/7.5 or TS-35/15 mounting rails. The unit features a compact 52.5mm (3SU) width design, which allows for significant space optimization inside control cabinets and distribution boards. Adopting the "Step Shape" architecture common in European building standards, the HDR-100 fits seamlessly alongside standard circuit breakers in shallow electrical panels. It supports a universal AC input range from 85VA to 264VAC (277VAC operational) and conforms to EN61000-3-2 harmonic current regulations.
Argument : The HDR-60 offers higher power density in a smaller mechanical envelope.
Evidence : With a width of only 52.5mm (3SU), the HDR-60 saves over 40% of rail space compared to traditional 60W metal-case industrial supplies. This enables engineers to specify smaller, more cost-effective enclosures without sacrificing performance.
Advantage 2: Enhanced Installation Safety (Class II)
Argument: Simplifies wiring and increases safety in hybrid civil/industrial environments.
Evidence : As an Isolation Class II unit, it features a double-insulated chassis and does not require an FG (Frame Ground) connection. This prevents ground-loop noise and simplifies deployment in locations where a reliable safety ground is unavailable, such as smart home or older building automation systems.
Advantage 3: Superior Thermal Management and Energy Saving
Argument : Reduces long-term operational costs and maintenance risks.
Evidence: The fanless natural convection cooling design combined with a wide operating temperature range (-30 to +70°C) ensures an extended MTBF (Mean Time Between Failures). Furthermore, the no-load consumption < 0.3W meets the stringent "ErP directive" for end-equipment power efficiency.
Building Automation:
Powering intelligent lighting controllers, HVAC systems, and security hubs.
Industrial Control:
Reliable DC source for PLCs, I/O modules, and HMIs in control cabinets.
Household Control:
Ideal for IoT gateways and smart home distribution boxes.
Telecommunications:
Compact power for small-cell stations and networking routers.
Q: Does the HDR-60 require a cooling fan for 60W output?
A: No, the HDR-60 is designed for natural convection cooling and can deliver full power up to 45-50°C ambient temperature without an external fan.
Q: Can this power supply be mounted in a standard breaker box?
A: Yes. Its "Step Shape" design is specifically optimized to fit alongside circuit breakers in standard residential and commercial distribution boxes.
Q: What happens if the output is accidentally short-circuited?
A: The HDR-60 features comprehensive short-circuit protection (Hiccup mode). The unit will automatically recover once the fault condition is removed.
