The CP-T 48/20.0 accepts a wide 3x400–500 VAC input range, enabling flexible sourcing across international sites and reducing the need for local transformers. This translates to lower wiring costs and simpler commissioning in multi-site deployments, with reliable 48 V DC output at 20 A (960 W) feeding PLCs, drives, and I/O modules. Hiccup-mode protection minimizes disturbance during transient faults, protecting downstream equipment and easing fault diagnosis with faster recovery. DIN rail mounting on TH35 profiles (TH35-15 and TH35-7.5) delivers rapid installation and standardized cabinet layouts, saving installation time and space in crowded panels. The unit operates from -40 to +70 °C and is rated IP20 for housing and terminals, enabling dependable performance in factory environments while maintaining compliance with EMC and safety standards. EMC immunity and broad standard certifications provide confidence for global deployments across machinery, packaging, and process automation.

FAQs
The unit mounts on TH35 DIN rails (TH35-15 or TH35-7.5) and is designed for standard enclosure spaces. Use a PH2 screwdriver, tighten input and output terminals to 1 N·m and 1.8 N·m respectively, and maintain the recommended 25 mm mounting clearance. It supports flexible wire sizes (0.2–6 mm² input, 0.5–16 mm² output) for reliable, code-compliant installations.
Input is three-phase 3x400–500 VAC (with a flexible range for DC operation 480–820 VDC). Output is 48 V DC at up to 20 A (960 W). The device uses hiccup-mode protection to handle overloads gracefully, ensuring the rest of the system remains powered while fault conditions are cleared.
Yes. The CP-T 48/20.0 supports 480–820 V DC input ranges, making it adaptable to DC-bus powered installations. Its 48 V DC output is ideal for PLCs, servo drives, and peripheral modules, with a robust 960 W rating that accommodates peak load requirements in automation panels.
The unit carries CE and UKCA declarations, UL 508 and cUR certifications, and UL/CSA references for multiple configurations. It also meets IEC/EN 61000 EMC standards for immunity and emission, UL 60950 safety requirements, and IP20 protection. These certifications support global deployments in regulated environments.
With a 960 W output, 3x input capability, and rugged IEC/UL compliance, you gain reliable control power with reduced downtime and fewer faults. Hiccup-mode protection limits stress on connected loads, potentially lowering maintenance costs. The device’s DIN-rail form factor also reduces cabinet space and installation time, contributing to faster commissioning and long-term operational efficiency.
