LED DC Electronic Load Simulator

120V, 12A, 300W

●  Voltage can be increased to 600V(option)


  • 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).
  • Not only CC, CR, and CP mode have parallel operation functions, but CV mode also has parallel operation functions.
  • 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 ℃.
  • Must be configured in 3302F〔single channel mainframe〕、3305F〔two channels mainframe〕or 3300F〔four channels mainframe〕and the mainframe with 150 sets Store / Recall memory.
  • Optional Interface:GPIB、RS232、USB、LAN.
  • Voltage can be increased to 600V(option)
  • The power input dimming frequency of 3345G & 33402G is up to 25KHZ that is the fastest and widest of bandwidth electronic load in the market.
  • The dimming control output of 3345G & 33402G is DC-10KHZ
  • New waveform generator plug in model 9923 adds user programmable battery dischargecurrent waveform simulation to Prodigit DC Loads


  • Each 3340G Series module has its own control and display panel, LED/CC/CR/CV/CP/ Dynamic modes, plug in 3300F 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.
  • 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.
