The SPC smart power conditioner from PQ Tech is an active harmonic filter series suitable for single-phase sub-distribution circuits in commercial buildings, shopping and entertainment centres and small industrial enterprises.
The power conditioner monitors harmonic current injected by nonlinear loads such as SMPS systems, IT equipment and electronic fluorescent lighting ballasts and generates anti-phase current so that incoming power lines only carry the clean current required for the attached load.
Being a single-phase device, it is suitable for phase-to-neutral voltages of 120-400 and is available in line current ratings from 30 to 300 A.
The device can be installed by simply connecting it in parallel with the load. Smaller units can be used for individual loads, whereas the 300 A models are also suitable for connection at sub-distribution board level.
For larger power applications, units can be paralleled. For example, in three-phase, 4-wire systems, three power conditioners can be connected between the individual phases and neutral thereby eliminating the 150 Hz triplen harmonic, which can severely overload the neutral.
