  Product description:

  ANEVT series high-precision bidirectional DC test power supply adopts high-frequency PWM rectification and bidirectional DCDC conversion technology, FPGA digital control technology, seamless switching between forward and reverse, automatic bidirectional operation, and full-power segment energy feedback grid function. Advanced digital control technology, ultra-high control accuracy, fast response, wider output voltage range, compared with the conventional two-way power supply, can achieve 0V~ full range of high-precision output. Rich programming test function, with different PC software can be used in a variety of applications.

  Product features:

  <1> Grid feedback function: It has two characteristics of power supply and load. Besides the performance of high-power dc power supply, it can realize the load function of energy automatic feedback to the power grid. and has outstanding advantages of energy saving, green environmental protection.

  <2>High precision output: Output voltage and current accuracy (+0.1%F.S). Fast dynamic response: 10% - 90% sudden loading and 90% - 10% sudden unloading output voltage response time is less than 5 ms; +90% ~ -90% forward and reverse switching time ≤ 10ms.

  <3>Mainstream high-frequency PWM rectification control technology, power factor ≥ 0.99, THD and injected harmonic current meet the requirements of national standard GB/T14549-93, high-quality energy feedback grid. ptimized bidirectional DCDC conversion technology, wider output voltage range and adjustable 0V-full range.

  <4> The advanced IGBT parallel technology, meeting the peak power and peak current output of 1.5 times and above the rated value.

  <5> CC, CV, CP three working modes.

  <6> Multiple protection functions: input over-voltage, phase loss, output over-voltage, IGBT over-heating, IGBT over-current, over-temperature protection, short-circuit current limiting protection.

  <7> Built-in EMI filter can well filter out interference signals caused by high frequency switching process.

  <8> Communication and remote control functions: standard CAN, RS232/RS485 communication interface and PC remote control software.

  <9> It has a programmable output slow-rising function.

  <10> Large-screen LCD display, compatible with buttons and touch screen operation, suitable for operation under various harsh working conditions.

  <11>Lock screen (key) function: When the customer does not operate the power for more than 5 minutes, the power will automatically lock the keyboard and touch screen input.
