Voltage Monitoring Type SW

Universal voltage monitor SW32V

Over- and undervoltage for DC-, AC- and 3AC voltages

Description

The voltage relay SW32V is a

high-grade voltage monitor with

a wide measuring-range for mo-

nitoring DC-, AC- and 3-phase

voltages for over- and/or under-

voltage.

In3-phasepowernetworksphase-

symmetry and phase-sequence

can also be monitored.

The limits are set in Volts. Thus

nominal voltages.

The digital display shows the measured value as well

as it helps setting the limits, switching-delays and

switching functions.

Application:

As voltage monitor in equipment for generation or

ditribution of electric energy, especially in photovoltaic

plants and block heating stations,

Monitoring of voltage in machines and plants to protect

them from damage caused by failure or deviation of

voltage.
