3.3 Operating area of the PLZ-4W
As shown in Fig. 3-3, the PLZ-4W can be used within the area enclosed by the con-
stant voltage line according to the rated voltage (L1), the constant power line
according to the rated power (L2), the constant current line according to the rated
current (L3), and the constant voltage line according to the minimum operating
voltage (L4) (operating area where speci
fi cations are guaranteed). For PLZ-4Ws
with the minimum operating voltage of 0 V, the speci fi cations are guaranteed at
input voltages at 0 V and greater. For 1.5 V input types, the speci fi cations are guar-
anteed at input voltages of 1.5 V and greater. If the current is decreased, these types
can be used even at voltages lower than 1.5 V. However, the speci
fi cations are not
guaranteed. (Actual operating area)
Minimum voltage at which the current starts
fl owing to the PLZ-4W is approxi-
mately 0.3 V.
The PLZ-4W detects no signal at an input voltage less than or equal to approxi-
mately 0.3 V and an input current less than or equal to approximately 1 % of the
range rating. If the input voltage is gradually increased from 0 V, no current will
fl ow until 0.3 V is exceeded. Once a current greater than or equal to 1 % of the range
rating (When PLZ-4W is set by the M range: greater than or equal to 1 % of H
range) starts
fl owing, the current can fl ow at voltages less than equal to 0.3 V.
If the minimum operating voltage (L5) in the actual operating area is reached, the
operating status on the display indicates C.R using outline characters (see section
4.4, “Display”).
