NDR-480 480W Industrial DIN-Rail Switching Power Supply

Executive Overview
The NDR-480 is an industrial-grade 480W DIN-rail switching power supply engineered for high-demand automation, process control, and embedded industrial systems. Designed with robust power stages, it delivers reliable DC bus regulation across wide operational conditions, offering selectable nominal outputs including 12V (40A), 24V (20A), and 48V (10A) configurations to match demanding field infrastructure.

Input & Electrical Specifications
Equipped with a universal AC/DC front-end, the NDR-480 supports a broad input span from 85VAC to 264VAC (47–63Hz) and 120VDC to 370VDC. It delivers peak conversion efficiency reaching over 89% with ultra-low leakage current (135% threshold shutdown with auto-recovery), and total short-circuit immunity. High dielectric strength isolation is validated at 3.0kVAC between input/output, 1.5kVAC input to chassis ground, and 0.5kVAC output to ground, with minimum 100MΩ insulation resistance at 500VDC.

Mechanical Packaging & Environmental Standards
The rugged metallic chassis measures 85 x 125 x 128.5 mm, tailored for standard TS-35/7.5 or TS-35/15 DIN-rail mounting. It performs reliably across temperatures ranging from -10°C to +60°C and 20% to 90% RH non-condensing operating conditions, making it an ideal choice for switchboards, industrial edge enclosures, and automation cabinets.
