ENERGY SAVER


ENERGY SAVER

* Programmable range of 25/5, 50/5, 100/5, 150/5,
* Automatic C.T ratio selector so that same unit can be used upto C.T ratio 250 / 5 Amp.
* Smooth and reliable change over to delta, when goes above set current.
* Compact size and easy to instal.
* “ADD ON” unit between existing star delta starter & motor.
* Advance microcontroller based technology, inherently more reliable and accurate.
* Direct digital display of current drawn by load.
* Built-in time totalizer for star running time to know saving
* Delay timer 1-99 second for delta to star change over.
* Star run indication on front.
* Used latest microcontroller based technology.
* Program setting by three soft membrane keys front panel.
* Built-in watch-dog circuit for fail safe operation.
* Delay timer 1-99 second for delta to star change over.
* Star run indication on front.

In any industries electrical motors accounts for 55% to 60% of the electrical energy consumption
Induction motors operate efficiently as long as they are loaded upto 60% to 85% loading. When
these motors are operated below 50% loading the efficiency and power factor is very low. During
lightly loaded condition (less than 50% loading), it is preferable to run motors in star instead of delta
which makes you reduce your electrical bill.

* Voltage across winding reduces to 58% of rated voltage and line current reduces to 1/3rd3
    Thus reduction in iron and copper losses, hence less power consumption, reduce power bills.
* Improvement in power factor and efficiency or no need of power factor correction capacitor.
* Energy saving from 5% to 35% depending on % loading of motor (no load to 50% loading.
  At 50% load minimum saving and at no load maximum saving).
* Decrease in line current which gives additional savings in cable losses and losses in switch
    gears.
* No need of changing motor to lower KW.

* Under loaded equipment like pumps, blowers, agitators, ball and roll mills etc. or In process
   where load varies at different stages (3 phase machines only).
* Machine shop industries: Like lath M/C, power press, drill M/C, Boaring M/C, etc. (3 phase
   machine only).
* I/D fan, F/D fan.
* AHU blower fan etc.
