Product Features

• Two-stage circuit of PWM rectification and bidirectional DCDC, achieving load of automatic energy feedback to the grid, energy saving, green and environment protection.
• Mainstream high-frequency PWM rectification control, power factor ≥0.99, THD and injected harmonic current meet the requirements of GB/T14549-93, high-quality energy feedback to the grid.
• Optimized bidirectional DCDC conversion, wider range of DC input voltage, 0V-full scale DC input.
• High-precision output: accuracy of voltage and current: ±0.1% F.S.
• Fast dynamic response: response time for 10%-90% sudden applied load and 90%-10% sudden shedding load: ≤5ms
• For testing of fuel cell industry, advanced IGBT parallel technology, low voltage large current stable control.
• CC, CV, CP modes.
• Multi protection: input over-voltage/under-voltage, lack phase, output over voltage, IGBT overheat, IGBT over current, over temperature protection, short circuit current-limiting protection.
• Built-in EMI filter to filter the interference signal caused by the high-frequency switching process.
• Communication and remote control: standard CAN, RS232/RS485 port and remote control software of the upper computer.
• Strict heat management, stable and reliable.
• Large-screen LCD display, compatible with buttons and touch screen, suitable for operation under various harsh operating conditions.
• Screen (key) lock: After the power supply is not operated for more than 5 minutes, the keyboard and input of touch screen will automatically be locked.
