ANELF(F) Series Dedicated DC Electronic Load

    ANELF(F) series fuel cell dedicated DC electronic load is an energy feedback DC electronic load developed for testing of fuel cell stack, fuel cell engine system, fuel cell backup power supply, etc.

Product Introduction

ANELF(F) series fuel cell dedicated DC electronic load is an energy feedback DC electronic load developed for testing of fuel cell stack, fuel cell engine system, fuel cell backup power supply, etc. It adopts high-frequency PWM rectification and bidirectional DCDC conversion, FPGA digital control, ultra-high control accuracy, fast response, energy feedback to the grid at full power; advanced digital control, it can achieve full range of input from 0V to full scale. Low voltage large current load input characteristics and energy feedback, suitable for testing of fuel cell stacks and fuel cell engine systems etc.

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.
