Servo Stabilizers

 

 

 

The Product of Sun Electrical Industries is Manufacturing of  Servo Stabilizers is the equipment which provides constant output voltage to load.

Generally, it has been observed that there is never a constant supply of voltage (230V in Single Phase or 415V in 3 Phase) in AC Main Supply. Usually, it varies from 150V-300V and 300V to 500 Volt. Hence, due to which the severe conditions can emerge like Over Load Conditions, Heavy Line Losses, Poor Power Factor, Problem of Machinery Damage, and many more. Generally, during daytime the connected load is more to main supply and hence there is dip (low voltage) and in night time the voltage supply is more as the connected load decreases. Due to such fluctuations in AC main supply it results in frequent breakdown, low production and also loss of energy. Nowadays, Power Companies insist the coustumers to install the Servo Stabilizers to improve power factor and the life of the machinery, to get the better results in power saving. But Voltage is also important factor to save the power loss. Technically it has proved that Transformers, Motors and all other machines works very efficiently and with minimum breakdown at constant voltage supply of 415V or 400V. Hence, installing Servo Stabilizer is useful not for minimum breakdown and life of machinery installed but also for the power saving in high time of huge energy crisis all over the world. The entire load can connected to one single Servo Stabilizer or can be installed according to the individual machine's requirement. But the cheaper idea would be to install One Servo Stabilizer for entire load.

“SEI” Servo Stabilizers is the brand name for manufacturing and it covers all problem mentioned above and is effective in power saving. 

Our range includes stabilizers in various specifications that suit the input voltage variations of industries, commercial buildings, residential buildings and small businesses.

Efficiency & Regulation:-The stabilizer have efficiency better than 95% at full load and voltage regulation of +/-1% from specified voltage from no load to full load.

Indications:- LED type indication lamps for the following are provided separately per phase.
1.         Input high & input low
2.         Input on & output on
3.         Output trip
4.         Indication of digital meter.

Specification Of Selection Servo Stabilizers:-

A) Voltage Fluctuation:
Note down hourly reading of your Input Voltage by a voltmeter(digital) for three days. Check the lowest voltage & highest voltage during the 24 hours. Pick the lowest & highest voltage & give some gap of 5% for more fluctuation & select the lowest & highest Input Range.

(B) Load Fluctuation:
Note down the hourly reading of your individual phase to neutral with good Condition ampere meter. If your load is balance in all three phase or within 10% of your load, balance type Servo Stabilizer is applicable. If your load is unbalance more than 10%, we suggest you unbalance type Servo Stabilizer. Unbalance type Servo Stabilizer give you correction of voltage in individual phase & helps you to save your equipments & power.
 
(C) Selection of Rating (KVA):
Check your all power connection (KVA) on which you want to fix the Servo Stabilizer & select it as per your connected load. You can install higher capacity servo stabilizer which is suitable for combine load of your plant. This will be economical and easy to maintain.
