PLZ-U
Specifications 8-5
Protection function
Overvoltage protection (OVP)
Turns off the load at 110 % of the rated voltage
Overcurrent protection (OCP)
Set the value in the range of 0 % to 110 % of the rated current of
H range. Trips at the value or 110% of the rated current of the
range, whichever is less.
The action taken when the OCP trips can be set to load off or limit.
Overpower protection (OPP)
Set the value in the range of 0 % to 110 % of the rated power of H
range. Trips at the value or 110% of the rated power of the range,
whichever is less.
The action taken when the OPP trips can be set to load off or limit.
Overheat protection (OHP)
Trips when the heat sink temperature reaches 95
°
C. The action
taken when the OHP trips is to turn the load off.
Reverse connection protection (RVP)
Short-term protection provided by a short-circuit system using a
protection diode. The action taken when the OHP trips is to turn
the load off.
Undervoltage protection (UVP)
Set the value to off or in the range of 0 % to 100 % of the rated
voltage.
The action taken when the OHP trips is to turn the load off.
Remote sensing
Sensing voltage that can be compensated
2 V for a single line
Miscellaneous
ABC preset memories
Saves settings (A, B, and C) for each operation mode of each
range
Setup memories
Saves four sets of setup parameters
Elapsed time display
Measures the time from when the load is turned on to when the
load is turned off (0.1 s to 99999 s)
Auto load off timer
Turns off the load after the speci
fi
ed time elapses (off or 1 s to
99999 s)
Delayed load-on
Turns on the load after the speci
fi
ed time elapses (0 ms to 1 s, 10
ms steps)
Parallel operation
Possible between adjacent load units (same model) in the frame.
Inter-frame control and external control
Inter-frame control
Controls up to four slave frames from the master frame.
Enables you to turn on/off the load, recall presets ABC on all
channels simultaneously, and recall setup memories 0 to 3.
External control
Recall input of preset mem-
ories A, B, and C
Recalls preset memories A, B, and C on all channels simulta-
neously
Setup memory recall input
Recalls the setup memory 0 to 3
Enable input
Enables the turning on/off of the load, recalling of presets ABC on
all channels simultaneously, and recalling of setup memories 0 to 3.
Load-on input.
Turns on the load on all channels simultaneously.
Load on status output
On when the load is on (open collector output)
Alarm status output
On when the alarm is on (open collector output)
Internal power output
5 V and maximum output current of 100 mA
Input signal
Low active, pull up to 5 V using 10 k
Ω
.
Low level input voltage: 0 V to 1 V, high level input voltage: 4 V
to 5 V
Output signal
Open drain, output withstand voltage of 30 VDC, output satura-
tion voltage of approximately 0.7 V, and maximum output current
of 100 mA.
