3. APPLICATION
OVP-11F voltage relay is designed to protect household appliances (refri-
gerators, washing-machines, PCs, video and audio equipment, etc.) con-
nected to it against inadmissible supply voltage de
fl
ections and impulse
noises in the power supply network.
4. FEATURES
•
Protection of connected devices against high/low overvoltage in the power
supply network
•
Turn-on delay for protection against repeated failures in the power supply
network
•
Fixed protection parameters for operation simplicity
•
Voltage relay status indication
•
Protective shutters in the output socket
•
Protective grounding contacts
5. TECHNICAL DESCRIPTION
OVP-11F voltage relay presents a device with an electronic circuit with mic-
roprocessor control assembled in the case with a wall plug and socket.
OVP-11F voltage relay has
fi
xed settings and does not need programming.
OVP-11F voltage relay provides the power supply disconnection of
appliances connected to it, if the power supply voltage exceeds speci
fi
ed
values, and automatically recovers the power supply within the speci
fi
ed
time after voltage normalization, in such a manner, it protects the appliances
connected to the power supply network against voltage swings dangerous
for them. At that indicators of OVP-11F display the voltage relay status.
