Product Overview
The PLZ-U Series Electronic Load Unit is a compact, high-performance, multi-
channel electronic load unit that has three operation modes: constant current, con-
stant resistance, and constant voltage.
The PLZ-U consists of a frame and load units. Load units are inserted into the frame
(control section) for operation. The PLZ-30F and PLZ-50F Frames can accommo-
date up to 3 channels and 5 channels of load units, respectively.
The current capacity or power capacity can be increased through a parallel opera-
tion of load units. The load units can be combined to produce a power capacity from
75 W to 750 W (when
fi
ve PLZ150Us are installed into the PLZ-50F).
In addition to high-speed response and highly precise preset resolution, various
functions are provided including the soft start function, variable slew rates, switch-
ing function, ABC preset memories, four setup memories, and sequence function.
Because the PLZ-U comes standard with GPIB and RS-232C communication func-
tions, it can easily be incorporated into various test and inspection systems. The
communication functions are useful for testing batteries, DC/DC converters,
switching power supplies, and multi-output power supplies.
