Line Voltage Measurement, Current /Voltage (optional) on Load
RMS line current measurement function
Line voltage read 50-60Hz; voltage in range:
90...530Vac for model with work voltage range 480Vac
90...660Vac for model with work voltage range 600Vac
90...760Vac for model with work voltage range 690Vac
Accuracy RMS voltage measurement
1% f.s. with neutral connected, 2% f.s. without neutral
RMS current measurement function
Load Current Read
Accuracy RMS current measurement
2% f.s. @25°C in start mode ZC e BF; in mode PA 2% f.s. with con-
duction angle >90°, 4% f.s. with conduction angle <90°
Function voltage measurement RMS on
load
Load voltage read
Accuracy RMS voltage measurement
on load
1% f.s. with VLOAD option measurement, (Otherwise, the value is
calculated from the values of line voltage and power delivered; ac-
curacy 2% F.S.)
Thermal drift for measure tension and
current in the load, tension of line
<0,02%/°C
Current and Voltage sampling time
0,25 ms
INDIG1,…,INDIG3 Digital inputs
Function
Configurable (default: disabled)
Only for INDIG3: PWM input (100Hz/0,03Hz) to check the %
value of power which depends on the cycle; this function lets
you to set a power set point by means of a digital signal (ex.
from PLC or controller with PWM output).
Type
