1-4 General Description PLZ-U
■ ABC preset memories
Three presets that are most frequently used can be stored for each operation mode
and range. This allows quick switching of settings even when the load is turned on.
■ Load simulations
In constant current and constant resistance modes, a sequence program can be cre-
ated with up to 255 steps at a minimum interval of 1 ms. Independent settings can
be entered on each channel simultaneously.
■ Outstanding operability
Setup operations have been consolidated on the frame panel. Each channel can be
configured with one hand while viewing the measured voltage and current. Rotary
knobs with an analog feel and simple interface make the operation of the PLZ-U
easy even for first-time users.
■ Load input terminal
The load input terminal is provided on both the front panel and rear panel making
the load unit suitable for embedded applications.
■ Remote sensing terminal
Remote sensing terminals are provided on both the front panel and rear panel allow-
ing more accurate characteristics tests.
■ Extensive protection functions
Equipped with overcurrent protection (OCP), overpower protection (OPP), over-
voltage protection (OVP), undervoltage protection (UVP), overheat protection
(OHP), and reverse connection protection (RVP) functions. Since OCP, OPP, and
UVP can be varied for each channel, protection can be optimized for each equip-
ment under test.
■ External control
External voltage reference can be applied and the load can be turned on/off on each
channel. You can recall channel-linked ABC preset memories, recall setup memo-
ries, and turn on/off the load from the frame control connector.
■ Inter-frame control
By connecting the frame control signal, multiple frames can be controlled from a
single frame. You can collectively turn on/off the load and recall reset values.
■ Setup memories
Four sets of panel settings can be stored. You can easily recall settings according to
the application and perform tests.
■ Standard GPIB, and RS-232C communication functions
GPIB and RS-232C come standard. Since panel settings, input voltage, current, and
power can be read through the interface, the PLZ-U can be embedded easily into
various test systems.
