380V Three-Phase Input 18V 250A Programmable DC Rectifier

This 18V 250A programmable DC rectifier is designed for heavy-duty industrial applications requiring stable and precise DC output. Powered by a 380V three-phase input, it delivers high efficiency, low ripple, and reliable performance even under continuous operation. The programmable control system allows users to set voltage, current, timing, and protection parameters with ease. Ideal for electroplating, electrolysis, hydrogen production, battery charging, and other demanding processes.

Technical Specifications

Input Power: three-phase 380V AC ±10%, 50/60Hz
Output Capability:
- Voltage: DC 0-18V continuously adjustable
- Current: DC 0-250A continuously adjustable
- Power: Max.4.5KW (18V ×250A)
Regulation Accuracy: Voltage ±1%, Current ±1%
Efficiency: ≥85% (IGBT high-frequency soft-switching technology)
Cooling System: Intelligent forced air cooling (temperature-controlled variable-speed fans, low noise)
Protection Features: Over-voltage, over-current, short-circuit, overheating, phase loss, and input surge protection
Control Modes: Auto-switching between CV/CC modes; supports local keypad or remote RS485 communication (Modbus protocol)；local panel control
Display Interface: LED/liquid crystal screen for real-time voltage, current, and status alerts
Operating Temperature: -10℃ to +50℃
Protection Rating: IP21 (dust and drip-proof)

Key Advantages

Flexible Adaptation: CC/CV auto-switching ensures precise control for electroplating processes.
Energy Efficiency: IGBT high-frequency inversion reduces energy loss, saving 10%-15% compared to traditional SCR rectifiers.
Compact Design: Space-saving and lightweight, suitable for workshops or labs.
Smart Thermal Management: Fans adjust speed based on load temperature, balancing cooling and noise.
High Compatibility: Wide input voltage range (±15%) accommodates grid fluctuations.

Applications

Precision Electroplating: Gold/silver plating, PCB electroplating, and other current-sensitive processes.
Small-Scale Electrolysis: Lab-based water electrolysis, precious metal refining.
Surface Treatment: Anodizing, electrophoretic coating, metal polishing.
R & D & Education: Electrochemical experiments in universities and research institutes.
