3. APPLICATION
OVP-16PD 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 (varistor)
•
Programmable disconnection thresholds and turn-on delay time
•
Nonvolatile memory of programmed settings
•
Multifunctional LCD display to show voltage level in the power supply net-
work, delay time and protection status indication
•
Protective shutters in the output socket
•
Presence of protective, fuse * 15А
5. TECHNICAL DESCRIPTION
OVP-16PD voltage relay presents a device with an electronic circuit with
microprocessor control assembled in a case with a wall plug and socket.
OVP-16PD 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-16PD 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.
* The fuse is replaced in the SC.
