Features and Strengths
High-frequency switching technology
Adopting high-frequency inverter technology, it is small in size, light in weight, high in efficiency (≥95%), and low in electromagnetic interference.
Modular design
Charging modules, monitoring units, etc. support hot-swap, which is convenient for maintenance and expansion (N+1 redundant configuration).
Intelligent management
Touch screen human-machine interface (HMI), supports parameter setting, fault record query, and battery health analysis.
Wide adaptability
Wide input voltage range (such as AC 380V±30%), adapting to power grid fluctuations; wide operating temperature range (-25℃~+55℃).
High protection level
The cabinet protection level reaches IP54 (some models), dustproof and waterproof, adapting to harsh industrial environments.
Function
1.DC power output
Converts alternating current (AC) into stable direct current (DC) to provide continuous and reliable DC power.
2.Intelligent charging management
High-frequency switching technology achieves efficient charging, supports constant current, constant voltage, and automatic switching between floating charge and equalizing charge, and prolongs battery life.
3.Battery management
Real-time monitoring of battery voltage, temperature, and internal resistance, with capacity prediction, automatic equalizing charge, and over-discharge protection functions.
4.System monitoring and protection
Real-time monitoring of input/output voltage, current, and insulation status, with overvoltage, undervoltage, overcurrent, short circuit, overtemperature and other protection functions.
5.Remote communication and control
Supports communication protocols such as RS485/Modbus, CAN bus, and Ethernet, and can be connected to power automation systems (such as SCADA) for remote monitoring.
Application
| Power Systems | DC power supply for power plants, substations, and converter stations. |
| Industrial | Critical automation and control systems in petrochemical, metallurgical, and mining plants. |
| Renewable Energy | Energy storage integration for PV power plants and wind farms. |
| Smart Buildings | Emergency power systems for high-rises, hospitals, and airport critical infrastructure. |
