Product Introduction
The CHNANMA NDR series is a reliable rail‑mounted switching power supply. As a professional industrial switching power supply, this slim‑type rail‑mounted power supply delivers highly stable DC output with options of 12V, 24V and 48V for sensitive electronic devices. Suitable for modern PLC systems and automation cabinets, its ultra‑slim form factor maximizes available cabinet internal space without compromising electrical reliability or thermal safety.
Key Features and Practical Performance
-High-Grade Construction: Every NDR unit is built with a high-efficiency transformer and high-conductivity coils. This superior conductivity helps lower internal heat build-up during 24/7 operation.
-Industrial Material Standards: The unit features a rugged metal housing. The precision ventilation cut-outs ensure consistent airflow across internal components.
-Cooling Structure: For high-capacity 480W models, an integrated cooling fan handles heat removal under full-load conditions. Lower-power models are engineered for silent, reliable free-air convection cooling.
-Intuitive Setup & Monitoring: Designed for tool-free installation on standard TS-35 rails, this rail-mounted power supply provides easy front-panel access. It includes clear L (Live), N (Neutral), and Ground terminals, a +V ADJ screw for precise voltage tuning, and a DC OK indicator for instant status checks.
-Operating Environment: Reliable performance across a temperature range of -20℃ to +70℃. (Note: Full-load operation up to 50℃; derating is required for temperatures above 50℃ to maintain stability).
Built‑in Four Safety Protections
To protect downstream PLC systems, sensors and motors, this NDR series slim rail‑mounted industrial power supply is equipped with comprehensive protection functions:
-Over‑voltage Protection: Activates when output voltage reaches 130%‑140% of rated voltage.
-Overload Protection: Activates when load power reaches 130%‑140% of rated power.
-Over‑temperature Protection: The unit triggers safety shutdown when internal temperature hits 65°C.
-Short‑circuit Protection: Instant output cut‑off upon short‑circuit occurrence.
Application Scope
This industrial cabinet power supply is widely used in:
Industrial Automation: Power supply for PLC systems and control logic units.
Cabinet Matching: Essential automation control power supply for distribution boards inside control cabinets.
Monitoring Systems: Deliver stable 24V DC power for security and smart monitoring equipment.
Industrial Lighting: Power supply for LED signage and lighting equipment.
