EMM-3
MULTIFUNCTION VOLT/AMMETER

GENERAL

The digital Multifunction Volt/Ammeter series EMM allow monitoring
the main electrical parameters present on a distribution line. The local
display of the electrical parameters is being made through 3 display
with red LED, which grant a good and simultaneous reading of
various measures. The intuitive selection of the measures to visualise,
which are signalled by their corresponding LED, completes a clear
and simple front panel, which offer a lot of useful information.
On top of the instantaneous measuring, these instruments visualise
the maximum peak of the main parameters (maximum peak and
maximum demand or maximum average value).
Multifunction Volt/Ammeter series EMM replace, in an unique device,
all the functions of voltmeters, ammeters and frequency meters,
permitting a great economic saving, due to reducing of dimension and
Wiring, so as optimising the instruments management, since one has
most of all in one, for electrical boards, switch-boards and Gen-Sets.

AVAILABLE MODELS

Several models, with various optional functions and outputs are available, either for flush mounting on front panel and for
DIN rail mounting.

INTRODUCTION

The EMM-3 is only featured for visualising the electrical parameters. The power supply is taken from the measured
voltage or self-supplied.

ACCESSORIES and OPTIONS

Accessories: transparent cover for frontal protection.
Options: power supply and measure voltages different than standard
measuring current inputs with internal CT's
