The PLZ-3W Series Electronic Loads are featured by
performance reliability and safety. Each Electronic Load
incorporates a current control circuit and renders highly
stable operation and rapid response. It is a
microprocessor-based instrument and provides advanced
functions and ease of operation.
The Electronic Load can be remote-controlled via a GPIB,
RS-232C, or MCB (Multi-channel Bus) interface (optional),
thereby making them applicable to various purposes. Typical
applications are for research systems in laboratories and on
production and inspection lines in manufacturing plants.
As the Electronic Load has a constant-power control
function, it can be used especially efficiently for battery
test. It can be used also to simulate a load of rapid response.
The Electronic Load is incorporated or can be optionally
incorporated with the various advantageous features as follows:
■ Constant power mode
The Electronic Load is incorporated with a constant power
(C.P) mode, in addition to the constant current (C.C),
constant resistance (C.R), and constant voltage (C.V) modes.
The constant power mode is especially advantageous for
battery life tests.
II Rapid response (50 /is)
When in the C.C mode, the current rises up or falls down
rapidly (50 μ$). This feature allows to evaluate accurately
the transient response characteristics of DC power supplies.
With this feature, the Electronic Load serves as an accurate
simulated load which draws the cunrent in an accurate waveform.
M Sequence operation
You can enter sequence operation patterns locally from the
front panel or remotely from a personal computer via GPIB or
oLher interface bus, and store the patterns on the internal
memory or on a memory card. The stored patterns can be
recalled and executed locally at the front panel or remotely
from the computer or with a trigger signal.
Sequence operation can be programmed in either one of the
following two types:
(a) Fast speed sequence : You can program sequences with
minimum 100 /is per step.
(b) Normal speed sequence : You can program sequences with a
ramp waveform per step.
Π Ease of operation
You can select each of the major functions by pressing the
corresponding key (one-key one-function select system). You
can finely adjust the setting value with the JOG/SHUTTLE
dials. You can enter values with the numeric entry keys by
using the RG11 .(optional). You can remote-control the
Electronic Load by using the RC02-PLZ Remote Controller
By using the setup function, you can save the values of
various settings and recall them as you need them. By using
the [A] , [B] and [C] keys, you can save the settings of
each operation mode in memory and recall them as you need
them. This features is very convenient when the same tests
are to be repeated.
■ A backlight LCD
The Electronic Load has a backlighted-type LCD (liquid
crystal display) which displays data, which can be easily
read being less affected by room illumination.
■ Various interface boards (optional)
The Electronic Load can be controlled over a GPIB, RS-232C
orMCB interface bus. This feature, as combined with the
programmed sequence control function, allows you a high
flexibility of system configuration.
The MCB is a unique interface developed by Kikusui. It
allows you to control up-to-fifteen instruments (electronic
load devices and power supplies) in an on-line mode via a
standard interface system (GPIB or RS-232C).
■ Memory card
The Electronic Load has a memoiy card slot as a standard
feature. The slot accepts a memory card (optional) on which
control sequence and setup data can be stored.
