Product Overview
The MDR-100 series is a 100W single-output industrial DIN rail power supply launched by Leyu Company, designed specifically for industrial control cabinets and equipment integration. This series offers three standard output voltage versions: 12V, 24V, and 48V, with rated powers of 90W, 96W, and 96W respectively, meeting the industrial load requirements of different voltage levels.
The MDR-100 series adopts a universal full-range AC input design (85~264VAC), adapting to various grid voltage environments worldwide without the need for manual voltage selection switches, effectively reducing the risk of misoperation. The power supply integrates four safety mechanisms: short circuit protection, overload protection, overvoltage protection, and over-temperature protection, which automatically cut off the output under abnormal conditions and recover after the fault is removed, ensuring the safe operation of downstream equipment.
This series features an ultra-slim plastic housing design and can be quickly mounted on TS-35/7.5 or TS-35/15 standard DIN rails. The installation process requires no additional tools—simply snap the power supply onto the rail. With free air convection cooling, no built-in fan is needed, resulting in quiet operation and higher reliability. Each unit undergoes 100% full-load burn-in testing before leaving the factory, ensuring stable output within the operating temperature range. Leyu Company possesses advanced manufacturing processes and complete testing equipment, producing products strictly in accordance with national standards, delivering stable performance and reliable quality.

Selection Suggestions:
12V powered devices (PLCs, sensors, small relays) → Choose MDR-100-12 to provide stable 12V power for low-voltage control circuits.
24V powered devices (industrial controllers, solenoid valves, stepper motor drives, HMI touchscreens) → Choose MDR-100-24, adjustable up to 30V, suitable for the vast majority of industrial automation scenarios.
48V powered devices (telecom equipment, LED lighting systems, high-power motor drives) → Choose MDR-100-48, adjustable up to 56V, with ripple & noise controlled within 200mVp-p.
Core Features
The MDR-100 series is designed around the actual needs of industrial applications, with main features including:
(1) Wide Voltage Input for Global Grid Compatibility
Supports 85~264VAC or 120~370VDC full-range voltage input, covering single-phase mains standards (110V/220V) in most countries and regions worldwide. It also accepts DC input, allowing direct connection in scenarios requiring backup battery power without additional conversion.
(2) Low No-Load Power Consumption for Energy Saving
The MDR-100 series has no-load power consumption below 1W, significantly reducing energy loss during standby or light-load conditions, helping users lower long-term operating costs and energy consumption indicators.
(3) Multiple Protections for System Safety
Built-in short circuit protection, overload protection (triggers constant current limiting at 105%~150% of rated power, automatically recovers after fault removal), overvoltage protection (each model has a shut-down threshold above the rated voltage), and over-temperature protection (shuts down output when temperature is too high, automatically recovers after temperature drops).
(4) Free Air Convection Cooling – No Fan Needed
The cooling method is free air convection. The power supply housing dissipates heat through air convection with no built-in fan, eliminating fan failure rates and noise, making it especially suitable for industrial environments with high reliability requirements and quiet areas such as offices.
(5) DC OK Relay Signal Output
The MDR-100 series provides a DC OK relay signal output contact (max 30V/1A resistive load) synchronized with the front-panel LED indicator. Users can feed the power supply's operating status back to a PLC or upper monitoring system via this relay contact for remote fault diagnosis and alarm.
(6) Fast DIN Rail Mounting
The rear of the power supply housing features a dedicated rail clip for direct mounting on TS-35/7.5 or TS-35/15 standard DIN rails. To install, simply snap the power supply onto the rail from top to bottom. To remove, use a flathead screwdriver to release the clip – no screws required, greatly reducing control cabinet assembly and maintenance time.

FAQ
Q: Which countries can the Leyu MDR-100 series be used in?
A: The MDR-100 series supports 85~264VAC full-range AC input, adapting to single-phase mains standards in the vast majority of countries and regions worldwide (including 100V, 110V, 120V, 220V, 230V, 240V, etc.) – no switching needed, just plug and use.
Q: What is the actual output power of the MDR-100 series?
A: The MDR-100-12 has an actual rated power of 90W, the MDR-100-24 is 96W, and the MDR-100-48 is 96W. The "100" in the product name is a series designation, indicating the design specification covers the 100W class.
Q: Can the MDR-100 series work in high-temperature environments?
A: The operating temperature range of this series is -10℃ to +60℃. When used at temperatures above 50℃, the output power must be derated according to the derating curve. Please refer to the derating curve chart in the product manual for specific derating ratios.
Q: How is the DC OK relay signal used?
A: The DC OK relay provides a normally open contact (max 30V/1A resistive load). When the power supply output voltage is normal, the relay is energized; when the output is abnormal, the relay releases. Users can connect this contact to a PLC input terminal, alarm indicator light, or buzzer for remote monitoring and fault alarm.
Q: How to recover after overload protection is triggered?
A: When the load exceeds 105%~150% of the rated power, the MDR-100 series enters constant current limiting protection mode. After removing the overload condition, the power supply automatically resumes normal output without manual restart.
Q: Can power supplies be connected in parallel?
A: The MDR-100 series does not support direct parallel connection to increase output power. If higher power is needed, we recommend selecting a single power supply with a higher power rating or choosing a redundant power supply module that supports parallel operation.
Q: Does the MDR-100 series have CE/UL certificates?
A: The MDR-100 series is designed with reference to UL508, TUV EN60950-1 safety standards and complies with CE marking requirements for EMC and safety. Bulk purchasers may request copies of relevant certificates from Leyu Company.
Q: How long is the warranty after purchase?
