| Description: |
These stabilizers are mainly to protect the Electrical and Electronic equipments, which are effected by the fluctuation in the input mains supply. In some cases the equipments do not operate when they are not used at the specified voltage. Our Servo voltage stabilizers by giving constant output with tolerance of +/-1% make these equipments operate efficiently and hence enhance their life. They also protect them from being damaged due to high and low voltage. The principle of operation of Servo Stabilizer involves comparing the output voltage with built in stable reference voltage source. The solid-state control circuit operates the motor whenever the output voltage falls or rises beyond a preset voltage.
The secondary winding of the buck boost transformer is in series with the main supply. The primary winding is connected to the motorized control autotransformer (Variac). Output voltage variation due to any reason makes the motor to move in proper direction, so as to feed the primary of the buck boost transformer a proper voltage which in turn produces voltage in the secondary to keep the output to set level with tolerance of +/-1%.
Special Features of servo voltage stabilizers :
1) Fully automatic solid-state glass epoxy plug in control card.
2) Very low internal impedance.
3) High reliability servomotor.
4) Wide frequency range from 45 Hz to 55 Hz.
5) No effect by any transient over voltage surges.
6) Voltage limit indicators.
7) Output Voltage adjustable.
8) Input/Output voltage monitoring.
9) Accuracy ± 0.5% to ± 1% from no load to full load.
10)Fast correction speed (20 volts to 40 volts per sec.)
11)Surge rating 10 times the rated current upto 2 seconds 3 times upto 60 seconds twice upto five minute.
12)Environment: The quoted current rating apply to ambient temperature from – 15° C to 45° C
13)Cooling - Oil / Air cool.
