## Description

AC rail monitor for electrical panels, color display, simultaneously measures 6 essential parameters voltage, current, power, frequency, energy consumed and power factor. Operates in the range 40-300VAC and up to 100A, with fast refresh 2 times per second. Includes integrated current transformer with through-hole for simple and compact installation.
AC voltage monitor, color, with rail mounting, used for monitoring 6 different values:
- Voltage in V
- Current in A
- Power in W
- Frequency in Hz
- Consumption in K Wh
- Power factor in PF
The assembly is of the rail type.
The device also integrates the current transformer ( CT , Current Transformer). and is accessible through a hole present through it.
