Dual DC Electronic Load



  • 5 digital V / A/W Meter.
  • Isolated two loads unit within one module.
  • Large LCD Display、setting values can be adjusted by rotary knob or push button.
  • 2 sets V. A. W. values can be displayed simultaneously.
  • OCP、OPP test function.
  • 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.
  • Power ON status value can be set.
  • Flexible CC. CR, CV, CP, Dynamic and Short operation modes.
  • SHORT time setting and SHORT_VH, SHORT_VL setting function.
  • Protections against V, I, W, and °C.
  • Voltage meter display the polarity positive(” + ”)or negative(” - ”)is selectable.
  • SYNC. Load ON function.
  • Optional  Interface : GPIB、RS232、USB、LAN.


  • 3330F Series Dual DC Electronic Load is a two load unit in one module. Each 3330F Series module has its own control and display panel, 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 remote controlled via RS232、Ethernet、USB and GPIB interface.
  • SHORT time setting and SHORT_VH, SHORT_VL setting function,also can measure Short Voltage and Current.
  • Dynamic can be simulated under CC, CP mode. The current Rise/Fall slew rate can be adjusted individually.
  • The additional OCP 、OPP test function will be more efficiency and accuracy on OCP, OPP testing.
  • 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 features 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.
