We offer servo controlled voltage stabilizer that is manufactured using high grade raw material. Our SEI AC voltage stabilizer confirms to IS - 9815. These servo controlled voltage stabilizer are used for providing steady output from fluctuating mains supply as input. We make use of modern precision and sophisticated Electrical and Electronic equipment, like computer & NC/CNC machine tools to design and manufacture these voltage stabilizers. Our stabilizers deliver excellent performance in most of the uneven conditions and can be used in equipment like induction Motors and heaters, deteriorates with fluctuating supply voltage. The "SEI" servo-controlled voltage stabilizer puts is an effective & economic solution to put an end to chronic voltage problem.  We offer varied types of stabilizer to meet the requirement of various industries. Additionally, we can customize these stabilizers as per the requirement of our valued clients. The customization can be done on the parameters such as input voltage range, output voltage, frequency and capacity.

Recommendations:

• 3 Phase models with single voltage-sensing relay and single drive motor are suitable for fairly balanced supply voltage and load.
• To overcome unbalanced voltage and load conditions, 3 Nos. 1 Phase units mounted in a single cabinet and connected in star are recommended.

Salient features:

• TO indicate input/output voltages a voltmeter with switch is provided
• Long term stability 1%
• Output Setting - 5 Volts by a lockable potentiometer
• High efficiency above 95%
• Indication for "Power ON", "Input too low" & "Input too high"
• A drive motor of special construction having high torque, low speed output with instant start, stop and reverse characteristic
• Short circuit proof

Construction:

The lower capacity units of the stabilizer, up to 50 KVA are in air cooled single unit construction. For the convenience of transportation & installation, the other higher capacity unit has two piece constructions. The inter-connecting cables and bus bars are provided with equipment. Further, both sections are floor mounting type and one among the two is oil cooled depending on requirement of the clients.

Operation:

The work of the voltage stabilizer is to add or subtract the incoming voltage so as to obtain steady voltage as output. The amount of voltage that is to be added or subtracted is obtained from the main itself. The subtraction and addition is done using a VARIPaC - a continuously variable voltage auto Transformer which is driven by a servo motor under the control of voltage sensing relay. The relay used in VARIPaC senses the output voltage continuously with a highly stable reference. These servo controlled voltage stabilizer relay is also responsible for directing the drive motor to correct the output voltage to the set level.
