Working Principle & Operation
Charging Mode
PWM switching power supply mode enables constant current and constant voltage charging with power conversion efficiency above 85%.
Discharge Mode
PWM boost circuit increases battery voltage, converts to AC power sent to the grid, and recycles discharge power for significant energy savings.
Performance Features
- Stability: Single-point independent constant current/voltage power supply with complete protection functions
- Accuracy: Four-wire principle design eliminates tester internal resistance interference
- Flexibility: Automatic channel closure for low voltage, undercurrent, overvoltage, or overcurrent conditions
- Reliability: Selected materials and fine craftsmanship ensure longer service life than industry peers
