Product Description
µP-based modular universal
utility meter and power ana-
lyzer with built-in program-
ming key-pad.
Particularly recommended for
the analysis of the electtrical
variables, for the multi time
periods (t1, t2, t3, t4) energy
metering and water/gas
metering. Housing for panel
mounting and IP65 (front)
protection degree.
