Device for supplying voltage to electric fence has clock generator for timing voltage or current pulses, phase coupled to mains voltage as reference voltage in synchronized manner

摘要

The device has a clock generator (14) for timing of voltage or current pulses applied to the fence. The clock generator is phase coupled to the mains voltage as a reference voltage in synchronized manner. The clock for the pulses is generated by summing mains oscillations or by frequency divider from the mains frequency.
