Features

• 

Up to four load boosters can be connected in parallel.

• 

The combination of PLZ2004WBs and a PLZ1004W master unit 
can create an electronic load of up to 9 kW and 1 800 A.
The combination of PLZ2004WHBs and a PLZ1004WH master unit 
can create an electronic load of up to 9 kW and 450 A.
The master unit displays the total current and total wattage. The 
units connected in parallel can be used as a single electronic load.

• 

The connection of the control cables is easy. The control cable 
used to connect between the master unit and the load booster and
