Outline

The PLZ-5WH2 high power DC electronic load series is where durable, reliable ingenuity meets multifunctional and high power design. Providing 5 variety of power range line-ups, from 1 kW bench top style model to high power model that can sink up to 20 kW of power in a single unit. Possible to easily selects applicable power range depends on 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 measures can be made with 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 addition, available to set in operation modes other than CV mode, the “UVPL*” setting keep the voltage less than UVP setting by controlling the current and the “UVPT” setting loads off by applying a current to reach the target setting voltage.
  

  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 proportional 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 Operation Voltage up to 1000 V
  Operating voltage ranges from 10 V to 1000 V.
  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 needs to have each unit connection. 12 kW and 20 kW models are included in accessory. 1 kW, 2 kW and 4 kW models are option.
  

  Parallel connection with PLZ-5WH series*
  Must be PLZ-5WH as a Master and update the firmware to newest version.
  *When parallel operation between 5WH and 5WH2, only same capacity model is available.

  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). Three up to 100 points can be registered, and the space between two points is linearly interpolated. The minimum voltage (0.00 V) and current (0.00 A) and the maximum voltage (1010.00 V) are fixed.
