Technical Optimization: Through designs incorporating soft-switching technology and line-frequency isolation transformers, the impact of load fluctuations during power-on and power-off on the circuit is minimized, high-frequency interference is suppressed, and system stability is enhanced.
Efficiency Performance: Some products achieve conversion efficiencies of 90–92% under half-load conditions, effectively reducing power loss. Since electricity is billed at single-phase rates, this saves users long-term operating costs.
Designed to meet the demands of complex environments and long-term use, our single- and three-phase amplifiers excel in protection and thermal management:
Protection Rating: IP54 dust- and water-resistant design (select models) enables indoor and outdoor installation, withstands wind and rain, and extends equipment lifespan.
Thermal Management: Intelligent air-cooling architecture ensures stable operation under high-temperature or high-load conditions.
Protection Features: Integrated multiple protections including overcurrent, overload, undervoltage, overvoltage, short circuit, and overheat protection, as well as hard-switch protection for both input and output.
Remote Monitoring: Supports communication protocols such as RS485, Modbus RTU, and CAN, enabling real-time monitoring of DC input/output voltage, current, power status, and more.
Modular Design: Plug-and-play structure reduces maintenance costs.
