The LEYU HDR-100 series is an economical, ultra-slim 100W industrial DIN rail power supply designed for installation on TS-35/7.5 or TS-35/15 mounting rails. The body is designed with a width of 70mm (4SU), allowing significant space-saving within cabinets. Following the "Step Shape" architecture, the HDR-100 fits perfectly into standard building distribution boards. It adopts the full range AC input from 85VAC to 264VAC (277VAC operational) and conforms to EN61000-3-2, the norm the European Union regulates for harmonic current.
Advantage 1: Optimized for Distribution Box Integration
Argument: The HDR-100 is specifically engineered for shallow mounting environments.
Evidence : Its Step-Shape plastic housing aligns with the profile of standard circuit breakers, making it the premier choice for residential and commercial distribution boards. Unlike standard industrial PSUs, its depth and height are optimized to fit behind the dead-front covers of common electrical panels.
Advantage 2: Enhanced Safety for Civil and Industrial Hybrid Use
Argument: The Class II rating simplifies installation and increases system reliability.
Evidence : Designed as an Isolation Class II unit, the HDR-100 features a double-insulated enclosure that eliminates the need for an earth ground connection. This not only reduces wiring complexity but also prevents ground-loop interference, making it safer for use in building automation and household control systems.
Advantage 3: High Energy Density and Thermal Stability
Argument : Delivers robust 100W output without the need for active cooling components.
Evidence : With efficiency up to 90%, the HDR-100 minimizes heat dissipation. Combined with its natural convection cooling design, it operates reliably in ambient temperatures from -30°C to +70°C. This fanless architecture ensures an extended MTBF (Mean Time Between Failures), reducing long-term maintenance costs.
Building Automation:
Powering smart lighting, HVAC controls, and security panels.
Household Control Systems:
Ideal for smart home hubs and IoT gateways in distribution boxes.
Industrial Control:
Reliable DC source for PLCs, HMIs, and sensor arrays.
Telecom & Networking:
Compact power for industrial switches and routers.
Q: Can the HDR-100 be used in residential electrical panels?
A: Yes, its step-shape design is specifically optimized to fit within standard residential distribution boxes alongside circuit breakers.
Q: Does this power supply require a ground wire?
A: No. As a Class II isolated device, it features double insulation and does not require a safety ground, simplifying wiring in older buildings.
Q: Is the output voltage adjustable?
A: Yes, the output voltage (e.g., 24V) can be fine-tuned via the "DC ADJ" potentiometer on the front panel to compensate for cable voltage drops.
