|High Voltage Relay
|Number Of Poles
This relay is designed using micro-controller technology. It is
very simple to use and at the same time very accurate and
reliable. It is guaranteed for the performance as per design
for the lifetime of the components, best available in market.
This relay is used for controlling the D.C. supply for under
voltage condition. The relay gets de-energised when the
supply voltage goes below the setting. Two changeover
contacts are provided for customer usage for indication and
Characteristics and features :-
Ÿ Micro-controller based design.
Ÿ Voltage monitoring for under voltage condition.
Ÿ Wide setting range through a knob over linearly calibrated
Ÿ Independently adjustable ON and OFF delay timers for
Ÿ ON/OFF differential is adjustable for accommodating
supply voltage change due to loading and unloading.

Working Principle :-
Two different supply input are provided for accurate setting of
the relay in the factory during testing and setting at the final
stage of production. One +ve supply is for operation of the
relay which changes due to energisation and de-energisation
of the electromagnetic relay used for outputs contacts. Second
+ve supply is for sensing the voltage supply which is provided
through a variable source for doing testing and setting of the
unit at the final stage of production in the factory.
During actual operation both the +ve supply inputs are
shorted as we use same supply for operation and sensing. The
relay has a stabilized reference voltage adjustable through
the under voltage setting potentiometer knob which is
compared with the supply voltage and accordingly the output
electromagnetic relay is energised / de-energised through
independently adjustable ON and OFF delay timers. The
reference voltage is further adjusted depending on the
ON/OFF state of the output relay according to the ON/OFF
differential setting to accommodate change in the supply
voltage due to loading / unloading
5 LED''s are provided or on the top of the unit with the details on the label.
This unit is auto reset. When the correct voltage is restored the relay gets energised
