3 Phase Servo Voltage Stablizer

3 Phase Servo Voltage Stablizer

Servo Voltage Stabilizer is commonly observed that, AC main supply is never 230 Volt or 415 Volt, but varies from 150 Volt - 300 volt and 300 Volt - 500 Volt. The difficulties caused by them are well known, such as Over Load Condition, Line Losses, Poor Power Factor and several other reasons. The three phase servo voltage stabilizer helps in constant voltage which is required to load is never constant, but in fluctuation manner. It is observed that during the daytime, the voltage is quiet low and during the night the Voltage is high then the normal.

Amf Panel

Amf Panel
An uninterruptible power supply (UPS) system is your bridge between mains power and your backup generators. Automatic mains failure (AMF) panels also referred to as automatic transfer switch (ATS) panels make the power switch to emergency standby generators in the event of a significant loss of mains power or total blackout. Without AMF panels, generators need to be operated manually and that can mean lost data, potential damage to electrical equipment and huge amounts of disruption.

ISOLATION & ULTRA ISOLATION TRANSFORMER

  • Isolation Transformer Specifications Phase
  • Single Phase Input Voltage
  • 220 Volts Input Voltage
  • 220 Volts Transformer Ratio
  • 1:1 Power Factor
  • 0.75 Lag to lead Frequency
  • 50 Hz VI Electric strength

  • 100 db Class Of Insulation
Transformers also provide an extremely useful feature called isolation, which is the ability to couple one circuit to another without the use of direct wire connections. There are applications where electrical isolation is needed between two AC circuit without any transformation of voltage or current levels. In these instances, transformers called isolation transformers having 1:1 transformation ratios are used.
