What does high-frequency mean? In electrical engineering, frequencies above 10 kHz are described as high-frequency. But for power tools this term is commonly used to describe all frequencies above the standard mains frequency of 50/60 Hz.
The High Frequency department specialises in frequencies higher than the standard 50Hz supply. The department has over 40 years experience dealing in the repair and sale of high frequency grinders, motors and rotary frequency changers operating up to 300Hz.
