Functions and Advantages

 

One button switch, bidirectional power & Regenerative load

Different from other bidirectional power supplies, IT-M3900B series is a regenerative power system which combines two devices into a 1U unit. It is both a bidirectional DC power supply and also a regenerative DC electronic load. You can switch between Source and Load with one button on the front panel.IT-M3900B not only saves space and equipment purchasing cost for you, but also enables you to connect DUT easily. It can switch seamlessly between source and sink mode fast and continuously, which avoids voltage or current overshoot effectively. IT-M3900B can be well applied to battery test, cell packaging equipment test, battery protection board test, etc.

  

Battery simulation function

IT-M3900B unique bidirectional design and variable output impedence makes it easy for the users  to set voltage/capacity/internal resistance/SOC quickly to define battery matrix quickly from the front panel, to simulate the charge/discharge characteristics of battery and assist with other tests. ITECH provides optional BSS2000 battery simulation software, then users can self-define the battery curve by setting common parameters, also can set battery initial capacity to verify the DUT characteristics under different battery status. Meanwhile, BSS2000 supports importing matlab battery matrix or CSV. file with battery charging and discharging curve, so as to simulate real battery charge and discharge characteristics.

 

With optional ITS5300 battery testing software, it can do the below testing items:

  • Road conditions simulation
  • Charging & discharging characteristics testing
  • Cycle life testing
  • Consistency testing
  • DCIR testing
  • Temperature testing
  • Capacity testing
  • Life testing
  • Reliability testing
  • Overcharge/over discharge endurance testing
