Product Code : SC 02
Brand Name : VELSON INSTRUMENTS SERVICES
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.
