High Power LED DC Electronic Load Simulator

600V, 12A, 1800W

●  New waveform generator plug in model 9923 
    adds user programmable battery
    dischargecurrent waveform simulation to
    Prodigit DC Loads


  • LED mode load for LED Power Driver test.
  • CC, CR, CV, CP, LED and Dynamic mode.
  • Simulate LED Forward Bias Voltage (Vd) and Resistance (Rd).
  • Fast Response for PWM dimming test.
  • Built-in dimming control signal for PWM dimming test.
  • Short circuit test by external relay (built-in short relay driver circuit).
  • 5 digital V / A / W Meter.
  • Protections against V, I, W, and ℃.
  • Optional Interface:GPIB、RS232、USB、LAN.
  • New waveform generator plug in model 9923 adds user programmable battery dischargecurrent waveform simulation to Prodigit DC Loads


  • Each 33430G Series has its own control and display panel, LED/CC/CR/CV/CP/ Dynamic modes, panel with 150 sets Store/Recall memory which provides load set-up more efficiently,also can be controlled intranet via RS232、Ethernet、USB and GPIB interface.
  • Short circuit test by external relay ( there is an optional fixture for short ), Short Time can be set and Short Voltage can be measured.
  • Built-in dimming control signal output is for PWM dimming test of LED driver.
  • Simulate LED forword Bias voltage (Vd) and Resistance (Rd).
  • Programmable Load ON/OFF voltage, GO/NG meter check, Voltage meter display  “ + “ or “ – “ is selectable and 150 sets Store/Recall larger memory is much advance feature for each different application. 
  • 150 sets test parameter and status storage function can call the storage memory real time in accordance with the auto sequence requirement.
