Voltage Relay
3. APPLICATION
OVP-17P 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 deflections and impulse
noises in the power supply network.
4. FEATURES
•
Protection of connected devices against high/low voltage in the power
supply network
•
Protection of connected devices against impulse noises in the power
supply network
•
Programmable disconnection thresholds and turn-on delay time
•
Nonvolatile memory of programmed settings
•
Multifunctional LED display to show voltage level in the power supply net-
work, delay time and protection status indication
•
Protective shutters in the output socket
•
Protective grounding connection
5. TECHNICAL DESCRIPTION
OVP-17P voltage relay presents a device with an electronic circuit with
mic
ro
processor control assembled in a case with a wall plug and socket.
OVP-17P voltage relay provides the power supply disconnection of appliances
connected
to it, if the power supply voltage exceeds specified values, and
automatically recovers the power supply within the specified time after
voltage normalization. An indicator on the front panel displays the active
voltage value in the power supply network and signals about its operation
mode. OVP-17P voltage relay is a programmable device. Buttons on the
front panel are used to set its parameters.
Set parameters of the voltage relay are saved in its nonvolatile memory.
