PLZ-4WH
Specifications
Unless specified otherwise, the specifications are for the following settings and conditions.
•
The warm-up time is 30 minutes (with current flowing).
•
TYP:
These are typical values that are representative of situations where the
PLZ-4WH operates in an environment with an ambient temperature of 23
°
C.
These values do not guarantee the performance of the PLZ-4WH.
•
After PLZ-4WH has been warmed up, it must be calibrated correctly in a 23
°
C ± 5
°
C
environment according to the procedures given in the operation manual.
•
% of set: Denotes a percentage of the input voltage, input current, or input power setting.
•
% of f.s:
Denotes a percentage of the rated input voltage, rated input current, or rated input power.
•
% of rdng: Denotes a percentage of the input voltage, input current, or input power reading.
