3-phase or single-phase monitoring relay for phase

3-phase or single-phase monitoring relay for phase
MRG1P
version 1.1
3-phase or single-phase monitoring relay for phase failure and voltage level control
1.
Device description
MRG1P is designed to control phase failure and set minimum and maximum voltage level of all three phases L1, L2,
L3. Relay has one output double-throw contact 8 A.

Function
Monitoring of Umax / Umin voltage levels
Monitoring of phase failure
If the voltage in any phase is under the set level, red
LED is Off and output relay is opened. If voltage in all
three phases goes over set Umax or below the set
Umin, red LED turns On and output relay will be
closed.
When voltage goes in between the Umin and Umax
levels and after the set time T elapses, output relay will
be opened (red LED turns Off).
There is fix hysteresis of 5% from measured value.
If Umax is set on OFF, relay controls only under voltage
If Umin is set on OFF, relay controls only over voltage
If all three phases are present, yellow LED is Off and
output relay is open. If any of phase is missing, red LED
turns On and output relay is closed. As a phase failure
the voltage drop under 165 V, at any phase, is
considered. Detection and reaction of failure is shorter
than 100 ms.
