Product Description
Ordering Key
32-bit µP-based smart power
quality analizer with a built-in
configuration key-pad.
The housing is for panel
mounting and ensures a
degree of protection (front) of
IP 65. The instrument is par-
ticularly indicated for those
application where there is the
need to control the power
supply quality. The variables
being displayed are more
than 400.
