Product Description

Switching of electrical equipments in industrial & commercial areas generates spikes up to 10000 Volts & high frequency Noises, thus distributing the sine-wave output.

The spikes can cause the failure of thyristors, Microprocessors, or other sencitive electronic devices. 

The high frequency noises can interfere with Digital-Electronic equipment causing data corruption, erratic behavior, loss of memory etc. 

Isolation / Ultra 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 isolate the voltage spikes and reduce noise from main with extremely high insulation resistance.

 Special Features
  
 
Symmetrical characteristics allow noise attenuation from both sides.
 
No impedance matching required.
 
No need for extra filter circuits.
 
Can be used where different groung potential exists or the groung of the equipment cannot be earthed. 
 
No Secondary effects like resonance etc., as with filters.
