The 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 a regenerative DC electronic load. You can switch between Source and Load with one button on the front panel.

  • 2-in-1 unit - a bidirectional power supply and a regenerative load
  • One button switch between source and load on front panel
  • Compact design, 1U@6kW, 2U@12kW
  • Voltage range: 10~1500V
  • Current range: -720A~1020A
  • Power range: ±12kW
  • Bidirectional energy flow between the DUT and the grid, seamless current switching
  • Master/slave parallel connection with patented technology
  • Efficient power regeneration - reduces the cost of electricity and cooling
  • CC/CV priority
  • Adjustable output impedance
  • Battery charge and discharge test
  • Battery simulation
  • Partial pre-compliant with LV123, LV148, DIN40839,
  • ISO-16750-2, SAEJ1113-11,LV124 and ISO21848 automotive testing standards (not 10V models)
  • Slope of voltage, current and power is settable
  • Simulation of dynamic driving conditions, up to 10 million points
  • 8 operation modes under Source mode: CC/CV/CW/CR/CC+CV/CV+CR/CR+CC/CC+CV+CW+CR
  • Multiple protection: OVP / ±OCP / ±OPP / OTP
  • Voltage transient drop protection/anti-islanding/power grid detection/pre-charge
  • Built-in USB,CAN and LAN interfaces
  • Optional GPIB, analogue and RS232 interfaces
