XDR-120R DIN Rail Power Supply | 12V / 24V / 48V (LED Power Supply)

XDR-120R Slim Industrial DIN Rail Power Supply – 12V / 24V / 48V

The HYRITE XDR-120R series is a compact single-output industrial DIN rail power supply with built-in DC OK and redundancy functions, designed for industrial control cabinets, automation equipment and other indoor applications.

Featuring a slim 30mm-wide metal enclosure, universal AC input from 90 to 264Vac and a power factor of 0.95, the XDR-120R delivers reliable 120W DC power in space-constrained installations. It is available in 12V, 24V and 48V output versions and supports standard TS35/7.5 and TS35/15 DIN rail mounting.

The built-in redundancy function supports parallel connection of two power supplies, while the DC OK relay contact provides output status monitoring for external control and monitoring systems.

Protection Functions

• Overload Protection: 120%–165% of rated power. Hiccup mode with automatic recovery after the fault condition is removed.
• Short Circuit Protection: Hiccup mode with automatic recovery after the fault condition is removed.
• Overvoltage Protection: Shunt-down protection, recovery after power is restarted.
• Overtemperature Protection: Shunt-down protection with automatic recovery. Automatic recovery can be customized.

Built-in Redundancy Function

The XDR-120R supports parallel connection of two single power supplies through its built-in redundancy function.

When two power supplies are connected in parallel, the maximum load must not exceed the rated power of either individual power supply. This configuration is intended for power supply redundancy rather than increasing the total rated output power.

DC OK Relay Contact

The built-in DC OK relay contact provides an indication of the DC output status for external monitoring and control systems.

Installation Guide

• Designed for indoor installation.
• Ensure the power supply is properly grounded before installation and operation.
• Maintain adequate ventilation and heat dissipation. Avoid installation in sealed, high-temperature environments or near flammable and explosive materials.
• Do not block the ventilation openings of the power supply.
• Keep the connection cables between the power supply and load as short as possible to minimize voltage drop.
• Tighten all terminal connections properly to prevent overheating caused by poor contact.
• Refer to the loading and ambient temperature derating curves when selecting the operating load.
