Indirect three-phase meter
EDMk
Electronic three-phase energy meter
with indirect connection for DIN rails or
adaptable to panels
Description
Electronic three-phase meter (active and re-
active energy) with an indirect connection for
DIN rails or adaptable to a panel; 4 quadrants
(measures the active (kW ·h) and reactive
(kvar ·h) energy consumed and generated,
both capacitive and inductive).
Other features include:
} }
Galvanic insulation transformers - ITF
} }
RS-485 Communications, depending on
the type
} }
Two digital outputs with optoinsulated
transistor
} }
Informs about possible connection errors
on the display
Application
} }
Used as a redundant energy meter to
verify the energy charged by the company.
The unit is fully sealable so that it can not
be tampered with
} }
Billing meter: measures energy in the di-
fferent tariff categories (up to 3, depending
on the type). Used to define the different
billing periods or to control the production
shifts.
} }
Cost control to obtain the consumption/
unit ratio in industrial processes, etc. This
type of control facilitates the definition of
more precise cost prices
