Zero Voltage Switches

We manufacture Zero Voltage Switches that are used for each phase to receive switching signals from a micro controller of 8051 family. Loads are connected in series with a set of triacs being driven by the opto-isolator. The micro controller is designed to generate output pulses after zero voltage pulse to ensure that the load is getting switched on at zero cross of the supply waveform. The zero crossing feature of the TRIAC driver, (an opto-isolator) ensures low noise generation thus avoiding sudden inrush of current on resistive and inductive loads. Here in this project we are using two push buttons for generating output pulses from the microcontroller randomly, not coinciding with zero voltage supply voltage of the waveform.
