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.
