Datasheet

Application
The digital Weigel Power Meters have been designed to display elec-
trical parameters in low voltage systems.
WPM 600 B - Z is suitable for use in 3 - phase 4 - wire systems 230/400 V.
This panel meter displays the following electrical parameters: voltage,
current, active power, reactive power, power factor, frequency, active
energy and reactive energy. The ratings are displayed one after the
other or can be selected by pressing a button.
Using the front - side buttons, the current transformer ratio can be set
and the energy values can be reset.
Functional Principle
Microprocessor-controlled digital measuring device that measures,
calculates and indicates electrical ratings.
WPM 600 B -Z has 3 voltage inputs and 3 current inputs to enable simul-
taneous evaluation of voltage, current and power for all three phases.
The meter must be connected via current transformers.
