Designed by Australia’s most experienced power protection team for Australian conditions a 100% owned Australian Company using strict quality control. 32 separate and discrete components working in both series and parallel provide a failsafe barrier against virtually all categories of electrical disturbances, so common with today’s power grids.

When it comes to minimising your equipment risk, we make no wild or glossy promises. Our products do what we say they do. The team at THOR Technologies have individually engineered each product to be the best in its class. Best price. Best performance. Best value.

Thor dynamic active Tracking circuit™ A unique THOR bonus - this (pat. pending) protection strategy encompasses self-diagnostic and corrective circuitry. Traditional power surge protection always relies on simple surge absorbing circuitry at pre-defined points on the wave form. However, THOR Dynamic Active Tracking™ monitors the sine wave, instantaneously sensing and clamping transient spikes and surges to a safe level, regardless of where they appear on the wave form. THOR additionally filters and cleans all incoming power and through its unique 3-Bank isolation, prevents EMI and RFI pollution as well as inter-circuit back EMF - all of which are major contributors to software glitches and hardware damage.

Note: 16 amp model now standard. (10 amp model by request only)
