Home > Servo Voltage Manufacturers Suppliers

Voltsafe has designed various type of voltage stabilizers to overcome the problem of voltage effectively. Servo Stabilizers are one of the best of stabilizers and are used for delicate electrical and electronic equipment, where the load needs a substantially constant voltage with close tolerance without introducing harmonic distortion
 


 
Voltsafe Engineering corporation is one of the leading manufacturers and exporters in India of Stabilizers and Transformer, Our brand name Voltsafe which is very well known for its quality and standard. We make all kinds of Stabilizers and Transformers like Three Phase Servo Stabilizers, Single Phase Servo Stabilizer, AC Stabilizer, Variac Transformers, and Manual Transformers. We make all type of custom built as well as special Transformer and Stabilizers in India as per customer's requirements.

 

Unbalanced Type 3 Phase Stabilizer

This type of stabilizer is more versatile and is the most commonly used type or use with three phase machines/loads. This basically consist of 3 single phase units of 1/3rd capacity each connected in STAR, as per IS 9815 in this type. The output voltage on all three phase are equal even if the input voltage and the loads connected on the Three Phase are entirely different (unbalanced). This uses motorsalong with 3 variacs and 3 sotid state control circuits.
 

Balanced Type 3 Phase Stabilizer

This employs a single control circuit. The three various are mechanically coupled and driven by a single motor. Sensing is done in one phase and other two phase get corrected correspondingly. This is suitable for use with equal (Balance). Supply on 3 phases and balanced load. Some unbalance in load can be tolerated but at a loss of accuracy in output voltage.

Salient Features
 - Fully Solid State Control Circuit
 - No Waveform Distortion
 - No effect of load power Factor

 - High Efficiancy

 - Auto/Manual Operation Facility
 

Controls Indications on Front Panel
 - Out put Adjustable by +- of Rated Output Voltage
 - In this case correction range will shift proportionately if the output voltage is set at any other voltage than Rated output voltage.
 

Upper and Lower Voltage Limit Indicator for Input Main:

 - When the input voltage goes above the specified input range, a red light glows. In case the input voltage goes below a green light glows.

Optional Accessories
 - Over Load / Short Circuit Trip:
 - Provided as standard feature by means of MCB in lower capacity for higher capacity this feature can be provided on request.
 - Single Phasing Protection: Protection against single phasing or reverse phasing can be provided in 3 phase stabilizers.
 - High / Low Voltage Frequency trip:
 - Automatic high and or low voltage cut off protection in case mains fluctuations go beyond the range of the stabilizer or failure of control circuit. This can be with or without time delay circuit facility stabilizer also can be made to trip when frequency goes beyond limit.
