5-26 Application Operation PLZ-U
Precaution when operating under high-speed load simulations
When using an external control, do not connect the common terminal of the external device
and the terminal of the EUT which connects to the negative polarity of load input terminal of
the electronic load.
Attach the ferrite core on the connecting wire between the external device and the electronic
load.

External voltage reference
By applying an external voltage reference in the range of 0 to 10 V, you can vary the
setting proportionally in the range of 0 % to 100 % of the rated value.
• The maximum voltage that can be applied across pins 1 and 3 of the CH
CONT connector is +12 V. Applying a voltage exceeding this value can
damage the PLZ-U.
• Accuracy is not guaranteed for voltages below 0 V or above 10 V.
• Pin 1 of the CH CONT connector is connected to the negative load input
terminal. Do not allow pin 1 to touch other pins.
