EV AUTOMATIC POWER FACTOR CORRECTION SYSTEMS Mod. C-PF/EV

Features

This panel enables the experimentation on industrial installations with electronic devices for the control of power factor correction of electric low-voltage uses (voltage of 400 V). Automatic power factor correction circuits with different capacitive steps controlled by an electronic unit can be assembled on the panel. Two power analyzers measure voltages, currents, active, reactive and apparent powers and power factor.

The instruments are confi gured in 3 single-phase, three-phase systems with or without neutral; their use is free in the circuit: e.g.: in the feed line, in users or power consuming facility, in a capacitive battery, etc…

The panel is made of insulating material where components are represented with their international electric symbols; electric connections are easier via cables and jumpers with safety plugs of 4 mm; no tool is used.

The electric user with different values of apparent-active inductive power is easily reproduced in laboratory with the combined help of variable resistive-inductive loads.

A value of active-reactive power ranging between 1300-1900 W + 1300 - 1900 Var, adjustable in 5..7 steps, is recommended for a very good experimentation.

Variable loads mod. RL-2/EV + IL-2/EV, or mod. RL-3/EV +IL-3/EV, or mod. RL-2K/EV, are recommended.

More Information

OPTIONAL ACCESSORY:

Software and programming cable (having to be ordered separately). Adding the programming software, via port RS232 (or USB with a converter) will enable to set and display (simultaneously) all the measures (current power factor, set power factor, average weekly power factor, voltage, current, reactive power of the installation) in the automatic power factor regulator in order to get a general view of power factor correction system. Moreover, the total time and the number of insertions performed from the start of the installation are shown for each step, for the preventive maintenance of contactors.
