Transient Tracking Technology

Precision Power's filters provide protection against transient voltages, spikes and noise. The design has kept pace with today's technologies through a rigorous Research and Development schedule and an ongoing programme of upgrading product performance.

These refinements allow our protection systems to quickly react to transient voltages and spikes on the powerline at any point in the Sine Wave, unaffected by line or load impedance. Transient voltages and spikes can travel along powerlines at speeds faster than one millionth of a second. But the Precision Power filter's circuitry responds within 10 billionths of a second to any disturbance ensuring reliable equipment operation.
