MCA PLUS II NETWORK ANALYSER
General characteristics
· The MCA Plus II network analyser is an electronic device that allows the reading of the main advanced parameters of a supply network in the
true RMS values.
· It is specially designed for its easy installation and set up, it requires the connection of four voltage terminals and three current transformers.
The capacitive control keypad in the front allows to change the displayed parameters in a few seconds. The MCA Plus II have LCD backlight display for an easy reading in all light conditions.
