    ANEVT(F)

  ANEVT(F) series dual-channel bidirectional DC power supply adopts high-frequency PWM rectification and bidirectional DCDC conversion, FPGA digital control, seamless switching between forward and reverse, automatic bidirectional operation, energy feedback to the grid at full power; advanced digital control, ultra-high control accuracy, fast response; two channels independently configured and not affect each other, which can be used in parallel to expand the DC output capacity and reduce investment by customer; abundant programming and testing functions, suitable for a variety of applications with different upper computer software.

  Features:

  Independent channel configuration: each channel is independently programmed, voltage, current and power parameters are set independently, and the operating parameters in programming mode are set independently. The channels are independent of each other and do not affect each other.

  Parallel channels: The two channels do not affect each other, and can be used in parallel.

  Grid feedback: both power supply and load characteristics, achieving the function of load for automatic energy feedback to the grid in addition to high-power DC power supply performance; energy saving, green and environment protection.

  High-precision output: accuracy of output voltage: ±0.05% F.S.

  Fast dynamic response: output voltage response time for 10%-90% sudden applied load and 90%-10% sudden shedding load: ≤5ms; +90%~-90% forward/reverse switching time: ≤10ms.

  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.

  Advanced IGBT parallel technology, efficient and reliable.

  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.

  Programmable slow-rise output.
