Product Description

The LE-CHG-121-80-3P system is the ideal solution designed to meet the growing demand for highly reliable, green, and energy-saving DC power in demanding industrial environments and modern communication networks. Housed in a compact enclosure with dimensions of 1800 × 600 × 600 mm, the system is engineered to operate reliably under extreme environmental conditions ranging from -40°C to +55°C. It runs on a 3-phase AC input (380Vac) equipped with built-in surge protection (SPD) and dedicated circuit breakers for AC input, DC loads, and battery branches. The system utilizes advanced high-frequency power conversion technology to deliver extremely low voltage ripple (< 200mV), ensuring smooth and protected output power for sensitive microwave and control electronics. It also supports Hot-Swap technology for seamless module replacement without powering down system loads, as well as an advanced battery management system that performs automatic self-tests, temperature compensation, and deep discharge protection (LVLD / BLVD).

Features

High Efficiency (≥93%): Advanced switching technology with intelligent module sleep mode to enhance system efficiency during partial load operation.
High Power Factor (PF = 0.99): Reduces reactive power loss on the electrical grid and improves overall power quality.
Modular & Hot-Swappable Design: Allows convenient maintenance and replacement of rectifier modules without interrupting load supply.
* Intelligent Battery Management:
- Automatic, quick, and cyclic battery self-testing.
- Deep discharge protection for battery and load branches (LVLD / BLVD).
- Temperature-compensated voltage regulation based on ambient temperature.
* Remote Monitoring & Control (LE-CHG-C200 Controller):
- Full support for Modbus-RTU and Modbus-TCP/IP industrial protocols.
- Integrated connectivity ports: 2x USB (Mini), 1x LAN, 1x RS232, and 2x RS485.
- Front panel LCD display showing live voltage, current, frequency, and alarm status.
- Historical log storing up to 1,000 alarm events.
Comprehensive Electrical Protection: Protection against input over/under voltage, output over voltage, over current, and output short circuits.

Applications

Telecom Infrastructure & 5G Base Stations: Powering macro/micro cell sites, fiber optic networks, and transmission equipment. Power Sub-Stations & Industrial Plants: Serving as direct-current emergency power units in power utilities and chemical plants. SCADA Networks & Data Rooms: Providing uninterruptible DC power for field controllers and monitoring equipment. Satellite Ground Stations: Delivering stable and clean power for satellite transmission systems. Railway & Metro Systems: Supporting trackside signaling, communications, and traffic control equipment. Energy Storage Systems (ESS): Functioning as central battery charging and DC distribution units.
