NDR-120-24 120W 24V 5A Industrial DIN-Rail Switching Power Supply

High-Efficiency Industrial Power Architecture

The NDR-120-24 switching power supply delivers robust 120W 24V DC performance engineered for space-constrained industrial control cabinets. Featuring an ultra-slim 40mm profile, this single-phase industrial power supply mounts directly to standard TS-35/7.5 and TS-35/15 DIN rails, maximizing rail density while maintaining superior thermal dissipation through an all-metal chassis.

Comprehensive Electrical Specifications

Designed with a universal AC input range from 85VAC to 264VAC (47-63Hz) and DC input tolerance from 120VDC to 370VDC, the unit outputs a stabilized 24VDC at up to 5A. It maintains a voltage regulation range of ±10%, low ripple and noise under 120mV, and operating efficiency exceeding 88%, fully meeting European Union harmonic current compliance.

Industrial-Grade Safety and Protection

The unit integrates constant current overload protection rated at 105% to 150% with auto-recovery, overvoltage shutdown above 135%, and complete output short-circuit protection. Rugged isolation parameters include 3kVac input-to-output withstand voltage, 1.5kVac input-to-ground, and 500VDC/100MΩ minimum insulation resistance, certified to EMC EN55022 Class B standards.

Ruggedized Environmental Performance

Engineered to operate reliably across demanding temperatures ranging from -10°C to +60°C and 20% to 90% non-condensing relative humidity, the rugged metallic enclosure ensures optimal thermal transfer and electromagnetic interference mitigation without requiring forced-air fan cooling.

Integration and Deployment

Optimized for rapid integration within automation control systems, PLC cabinets, IIoT edge gateways, and industrial field instrumentation, the NDR-120-24 provides seamless snap-on DIN rail assembly backed by heavy-duty screw terminal blocks for secure, high-vibration wiring.
