VOLTAGE MONITOR & SINGLE PHASING PREVENTOR

The line voltage fluctuations, single phasing and frequent disappearance and performance of the mains supply causes a lot of head ache to a former. Whenever the supply voltage reappears after remaining OFF for a certain duration, the farmer has to abandon al his other jobs to reach the starter for starting the pump motor. Sometimes he has to walk through his fields covering a long distance to start the motor.

Considering the above problems the voltage sensing type Single Phasing Preventor of the SAVE series has been specially developed by PRINTRONIX ENGINEERS PVT. LTD.

SAVE is carefully designed to monitor the occurrence of any abnormality in the 3-phase supply and accordingly stop the motor. SAVE can be connected in such a way so that when the normal supply is resumed the motor starts automatically. 

SAVE is designed to work on the principle of voltage sensing without any requirement of NEUTRAL or EARTH connection. Because of this design, it can be used with a motor of any rating. It also ensures total protection by supplementing a current sensing protection already provided by modern overload relays.

  

FEATURES  :

  • Can be connected for MANUAL as well as AUTOMATIC operation of the pumps.

  • Inbuilt delay takes care of sudden fluctuations.

  • Designed to take care of large fluctuation in the supply voltage.

  • Sleek and simple design of the cabinet facilitates easy mounting and easy connection.
