Description: ELECTRONIC LOAD
Information:
                                    Model PLZ-72W Electronic Load is a highly versatile device
which can be operated either in a constant current mode or
in a constant resistance mode and is capable of handling two
loading levels by electronic switching. The PLZ-72W is
incorporated with automatically-resetting protectors to
guard against the various types of overload. Major features
of the PLZ-72W are as follows:
(1) Provided with a digital voltmeter/ammeter (3-1/2 digits).
(2) Provided with two 10-turn potentiometers to set two
levels of loading current.
(3) Has a built-in oscillator for switching timing (1 mS -
100 mS) between two levels of loading current either in the
constant current mode or in the constant resistance mode,
(4) When in the constant current mode, the loading current
can be remote-controlled with an external voltage or
resistance signal. Remote control can be done with an
external resistance signal also when in the constant
resistance mode.
(5) One-control parallel operation of multiple units can be
done.
That is, two or more unit can be connected in parallel and
all of them can be simultaneously controlled simply by
controlling only one of them.
(6) Provided with automatically resetting protectors to
guard against overvoltage, over current, overpower,
overheat, and reverse- polarity connection of the input.
(7) Rack mount is possible. That is, although the PLZ-72W
normally is supplied as a bench-top instrument, it can be
installed on an EIA Standard rack or a JIS Standard rack by
using a mounting frame and brackets which are available as
options.
