Read MoreThe Camtec CPS-EC480 Series is a high-precision, DIN rail-mounted DC power supply and battery charger engineered for high-performance and long-life operation in demanding industrial environments. With a continuous output power of up to 480W and efficiency levels reaching 92%, it is a reliable solution for applications such as DC motor drives, battery-backed control systems, industrial automation, and DC-UPS infrastructure.
A key advantage of the CPS-EC480 Series is its ability to automatically switch between constant voltage (CV) and constant current (CC) modes, enabling the unit to safely manage both steady-state loads and high inrush current devices without performance degradation. This makes it ideal for driving dynamic loads or charging large battery banks under varying conditions.
The CPS-EC480 supports precision adjustment of both output voltage and current via high-resolution potentiometers, and provides real-time output current monitoring for integration into supervisory or diagnostic systems. With output voltage options from 24Vdc to 300Vdc, robust overload and thermal protection features, and optional conformal coating for harsh environments, this German-engineered power supply is built for stability, safety, and flexibility.
It meets international safety and EMC standards including EN61010-1, EN62368-1, and EN55032 Class B, ensuring suitability for installation in critical industrial systems.

Features
- CV/CC Auto Mode: Seamlessly switches between constant voltage and constant current modes, supporting both load operation and battery charging without voltage instability or foldback.
- Real-Time Output Monitoring & DC-OK Relay: Integrated 0–5V current monitor output provides accurate, live feedback of load consumption, while a built-in DC-OK Relay indicates loss of input power, low output voltage, or thermal shutdown - enabling reliable system supervision and fault detection.
- Adjustable Output Ranges: High-precision potentiometers allow fine-tuning of both voltage and current across models ranging from 24Vdc to 300Vdc output.
- Inbuilt Protection: Includes continuous short-circuit protection, over-voltage shutdown, thermal shutdown with auto-recovery, and open-circuit safety.
- DIN-Rail Mount & Natural Cooling: Compact metal housing with tool-free DIN rail mounting and convection cooling ensures fast installation and reliable thermal performance in tight spaces.
- Conformal Coating Option: Available with a durable acrylic coating to protect against moisture, dust, and temperature cycling in harsh or outdoor-exposed environments.
