  • SHORT time setting.
  • Protections against I,W,°C and over-voltage alert.
  • Voltage meter display the polarity positive(”+”)or negative(”-”)is selectable.
  • Optional Interface : GPIB、RS232、USB、LAN.
  • Support MPPT CV test function for solar panel
  • Built-in soft-start circuit function allowing the U.U.T. power supply to be directly connected to the 34300E series load input terminal, no longer need a large relay switch with an external soft-start circuit.
MORE DETAIL CLOSE

 This series is unavailable in Europe and the United States.

 

  • 34300E Series has its own control and display panel, CC / CR / CV / CP / Dynamic modes, 150 sets Store / Recall memory which provides load set-up more efficiently, also can be remote controlled via GPIB、RS232USB and LAN 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 and there is an external signal input for a Arbitrary Waveform to simulate load current.
  • Single key for OCP、OPP test function will be more efficiency and accuracy on OCPOPP 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 feature for each different application.
  • 150 sets test parameter and status storage function, user can recall the storage memory real time in accordance with the auto sequence requirement.
  • Maximum Voltage up to 1250 V provide an idea testing solution for Power Factor Correction test.
  • Master / Slave control units maximum up to 1 MASTER, 7 SLAVE.
