Servo Stabilizer :

Electrical energy has become a basic necessity for our present living conditions. Electrical & electronics equipment from ordinary bulbs to sophisticated computer stations, from tiny toy motors to huge machinery motors, consume electrical energy. At any given instant a group of such units are being switched on or switched off at various location throughout power distribution lines. Due to such addition or subtraction of loads, the supply terminal voltage fluctuates. The voltage fluctuation can be controlled manually or automatically by various methods. The safest, surest and the most accurate of them all is Servo Controlled Method, which is widely accepted. SAKTHI Servo Controlled Voltage Stabilizer has been developed after immense study of the fluctuation problems and research in the field. The major advantage of having an  SAKTHI Servo Controlled Voltage Stabilizer is that the right from the transformer and variac circuit, all the components are manufactured and assembled in-house with assured quality control at every stage of manufacture. The performance of any electrical equipment is optimum at its rated voltage. Both over-voltage and under voltage produce harmful effects. Under voltage generally reduces efficiency, whereas over voltage shortens life.

Isolation Transformer :

Switching of electrical equipments in industrial & commercial areas generates spikes up to 10000 Volts & high frequency Noises. The spikes can cause the failure of Microprocessors based circuits or other sensitive electronic devices. The high frequency noises can interfere with Digital-Electronic equipment causing data corruption, loss of memory, erratic behavior of memory etc.

Isolation Transformers eliminates such noises & attenuates the spikes to minimal values, providing complete protection against such electrical disturbances. It consists of a double wound transformer with extremely low coupling capacitance to galvanically isolate the voltage spikes and reduce noise from main with extremely high insulation resistance.

Isolation Transformer

Salient Features:

  • Galvanic Isolation between primary and secondary winding.
  • Provides Isolated Neutral.
  • It protects microprocessor/microcontroller based system from dangerous noises and reduces the failure of drive.
  • Where there is a problem of Neutral in three phase connection from power distribution company, Delta/star isolation transformer will take care for the safety operation of load. (In this transformer Input Neutral from power distribution company is not used. Transformer output will provide isolated neutral for safe operation of load.)
  • Better Voltage Regulation (Regulation ≤ ±5% for 100% load current changes at unity power factor)

Optimum design for long life with reliability.

Ultra Isolation Transformer :

This is an advanced version of  Isolation Transformer. Construction of this is very different from the regular isolation transformer. In this secondary coils are split (or primary and secondary coils) as two or more coils according to the capacity of the transformer. The shielding method is also different because of the construction style. There is an inductance created between the coils because it is split. This inductance will give you more noise attenuation. As primary coil is not wound on top of the secondary coil the coupling capacitance is less. This is mainly required for wireless stations and costly life saving medical equipment’s.

Ultra Isolation Transformer

Advantages Of Ultra Isolation Transformer:

  • High noise attenuation level even in the high frequency application
  • Reduced coupling capacitance
  • Core will not saturate even if the applied voltage is high
  • Suitable for higher harmonic area installation
  • Because of the lesser heat dissipation the life of the transformer is very high
