Description

The functions of the 63800 series loads are the same except the variations on input voltage,
load current, and power ratings. They provide simulated loading current for the test unit.
They can be operated independently in AC load simulation and DC load simulation.
There are two groups of keypads on the electronic load front panel shown in Figure 1-1. They
are Function keypad and Entry keypad from left to right.
