Company Profile

30V 70A High-Precision Battery Charging Rectifier – 120V Single-Phase Input Programmable DC Power Supply

This 30V 70A battery charging rectifier is designed for applications that require stable and safe charging performance. With advanced IGBT high-frequency technology, it delivers efficient and low-ripple output under a 120V single-phase input, helping extend battery service life. It allows precise adjustment of voltage and current and includes multiple protection features. Suitable for charging lead-acid, lithium, and various other battery types, it is a reliable and intelligently controlled professional power solution.

Technical Specifications

Input Power: single-phase 120V AC ±10%, 50/60Hz
Output Capability:
- Voltage: DC 0-30V continuously adjustable
- Current: DC 0-70A continuously adjustable
- Power: Max.2.1KW (30V ×70A)
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.
