PLZ-5WH2 Series

Compact High Voltage DC Electronic Load (CC/CR/CV/CP/ARB) : 5 Models



Outline

The PLZ-5WH2 high power DC electronic load series is where durable, reliable ingenuity meets a multifunctional, high-power design. Providing 5 varieties of power range line-ups, from 1 kW a bench top style model to high power model that can sink up to 20 kW of power in a single unit. Possible you can select the optimal capacity according to the load. Load simulation can be achieved faster than ever before thanks to the reliable, high speed design of the PLZ-5WH current control circuits. Accurate current measurements can be made with an extremely high-setting resolution. A color LCD display allows for highly visible, user- friendly front panel operation. RS232C, USB, and LAN digital interfaces are included as standard for simple integration into any system.

Features

  • Operation Modes
    The following five operation modes are available on the PLZ-5WH2. In operating modes other than CV mode, you can also set “UVPL,*” which controls the current, so that the voltage does not drop below the UVP setting value, and “UVPT,” which turns off the load so that the current doesn’t overflow.
    Constant current (CC) mode When a current value is specified, the current is kept at that value even when the voltage changes.
    Constant resistance (CR) mode When a conductance value is specified, the product sinks current proportio-nal to the voltage variation by using the value as a proportionality constant.
    Constant voltage (CV) mode When a voltage value is specified, the product runs the current so that the voltage is kept at that value.
    Constant power (CP) mode When a power value is specified, the product runs the current so that the power is kept at that value.
    Arbitrary I-V charac-teristics (ARB) mode The desired load characteristics can be set by specifying multiple arbitrary voltage values and current values as I-V characteristics.

    * "UVPL" is the "+CV mode" in PLZ-5W series


  • Wide Ranging Operating Voltage up to 1000 V
    Operating voltage ranges from 10 V to 1000 V.
    The minimum operating voltage required to sink current is 1.5 V.
  • Maximum Slew Rate of 20 A/μs
    The PLZ-5WH2 series boasts a 20 μs rise time*, easily satisfying the critical needs of power supply evaluation tests demanding a fast transient response.
    *When using the PLZ20005WH2
  • Parallel Operation
    Up to 100 kW with parallel operation (Max. 5 units)
    Parallel operation (max. 5 units) is available on all models by simply connecting an optional parallel operation cable. This feature is available even among different models for a wide range of high power. (up to 100 kW / 2000 A)
    *A parallel cable is required to connect each unit. It is a standard accessory for 12 kW and 20 kW models, and optional for 1 kW/2 kW/4 kW modes.

    Parallel connection with PLZ-5WH series*
    After updating the 5WH series firmware to the latest version, operation is possible by setting the 5WH as the master and the 5WH2 as the slave.
    *Parallel operation of 5WH and 5WH2 is available only for models of the same capacity.

    Maximum current and power during parallel operation using the same model

    Model Parallel operation number Maximum current Maximum power
    PLZ20005WH2 2 800 A 40 kW
    3 1200 A 60 kW
    4 1600 A 80 kW
    5 2000 A 100 kW
  • Communication Interface
    LAN(LXI), USB and RS232C standard digital interface. *GPIB Option
  • Arbitrary I-V Characteristics (ARB) Mode
    In ARB mode, arbitrary I-V characteristics can be set by registering multiple I-V characteristic points (pairs of voltage and current values). Vales can be registered from 3 to 100, and linear interpolation is performed between the values. Minimum voltage (0.00V), current (0.00A) and the maximum viktage (1010.00V) are fixed.
