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.
In 3-phase power networks phase-
symmetry and phase-sequence
can also be monitored.
The limits are set in Volts. Thus
the device can be used at dierent
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.
