VR-101F
3. APPLICATION
VR-101F voltage relay is designed to protect household appliances (refrige-
rators, washing machines, PCs, video and audio equipment, etc.) connected to
it against inadmissible voltage
fl
uctuations in the power supply network.
4. FEATURES
•
Protection of household appliances against voltage swings
•
Restarting delay for connected equipment protection
•
Fixed protection parameters for operation simplicity

fl
ame-retardant case
5. TECHNICAL DESCRIPTION
VR-101F voltage relay presents a device with an electronic circuit with micro-
processor control assembled in the case with a wall plug and socket. VR-101F
voltage relay has
fi
xed settings and does not need additional programming.
VR-101F voltage relay disconnects the power supply to electrical appliances
connected to it, if the power supply voltage exceeds speci
fi
ed values and it
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, indi-
cators of VR-101F display the voltage relay status.
