NDR 120W 24V Din Rail-Mounted switching power supply Features 24v 5A

Space-Saving Architecture and Universal Grid Compatibility

Engineered for high-density industrial control enclosures and automated machinery panels, this ultra-slim 120W DIN-rail power supply optimizes cabinet real estate with a narrow 40mm profile. Designed for quick snap-on mounting on standard TS-35/7.5 and TS-35/15 top-hat rails, the unit minimizes installation time and eliminates the need for auxiliary mounting hardware. To ensure seamless operation across global power grids, the power supply features a universal wide-range input accepting 85 VAC to 264 VAC or 120 VDC to 370 VDC. This broad input window provides inherent protection against line voltage fluctuations, brownouts, and transient surges commonly encountered in heavy industrial environments, making it an ideal choice for factory automation, process control systems, and distributed I/O architectures.

High-Efficiency Energy Conversion and Precision Output Regulation

Available in versatile factory-tuned output variants including 12V DC at 10A, 24V DC at 5A, and 48V DC at 2.5A, this power supply achieves an outstanding energy efficiency rating of up to 89%. The elevated operating efficiency drastically minimizes internal thermal dissipation, allowing for reliable fanless convection cooling and reducing overall thermal stress inside sealed NEMA or IP-rated control cabinets. To accommodate long wiring runs and custom load requirements, the output voltage is field-adjustable by +/-10% via a front-panel trimmer potentiometer. Electrical stability is maintained through tight line regulation (+/-0.5%) and load regulation (+/-1%), while low ripple and noise characteristics under 150mV peak-to-peak protect sensitive programmable logic controllers (PLCs), human-machine interfaces (HMIs), instrumentation, and communication gateways from electrical interference.

Comprehensive Protection Topology and Industrial Isolation Standards

Built to withstand severe operational stress, the power supply delivers uninterrupted performance across an extended ambient temperature range from -10 degrees Celsius to +60 degrees Celsius. The robust electrical protection suite includes constant-current overload limiting between 105% and 150% of rated capacity, overvoltage shutdown triggered above 135% of nominal voltage, and continuous short-circuit protection with automatic recovery once fault conditions are cleared. Enhanced operational safety is guaranteed by a high galvanic isolation withstand rating of 3 kVAC between input and output, alongside low earth leakage current, ensuring full compliance with stringent international safety standards and preventing ground loop disruptions in complex industrial networks.

Mechanical Ergonomics, Fast Initialization, and Power Hold-Up Capability

Housed in a ruggedized, corrosion-resistant chassis measuring 40mm wide by 125mm high by 113mm deep and weighing 707 grams, the unit provides superior mechanical integrity against operational vibration and mechanical shock. The power supply offers rapid system startup with an initialization time of less than 500ms, accompanied by an extended hold-up time of up to 36ms at 220 VAC. This generous hold-up capacity ensures continuous, uninterruptible DC power delivery during brief AC mains sags, micro-cuts, and phase transitions, preventing ungraceful shutdowns of critical automation processes, robotic cells, building management networks, and industrial Internet of Things (IIoT) infrastructure.
