Phase Failure Relays

Reliable protection for three phase systems

Function:                                                 
These relays sense the negative
sequence voltage components of the
system supply & these are best suitable
for 3 phase loads.
They offer protection against phase
failure, phase unbalance, phase
sequence reversal conditions which are
dangerous to the motor winding and
cause motor burnouts.
Available in DIN rail...

Engine Protection Relay


Function
It protects the engine from
 a) Over Speed,
 b)Low Oil Pressure,
 c) Low Fuel,
 d) Hi-RadiatorTemperature.
It has an electronics protection system that gets input from various sensors of speed, oil pressure, fuel-level and radiator-temp. These inputs are constantly monitored and compared with their respective limiting values.
The moment, any one or more parameter crosses their limit, separate LED indicator glows, hooter actuates and a timer (30-60...

Water Level Controller

WL21P a low cost, reliable, IC based water level controllers. It keep constant watch on the water level and switch on or off the pump motors subject to availability of water at the reservoir and requirement level set at the upper tank.

Working Principle:

Series PWL21P is designed to operate with electrode type to sense the water level. Stainless Steel sensors with connector box are installed both at over head tank and reservoir.

No dry run of motor and No over flow...
