FEATURES & BENEFITS

AIM Active Harmonic Filters:

• AIM is available from 25A to 400A (over 1000A paralleled) in voltage ratings from 208V to 600V. Ratings given are ‘harmonic cancellation current’. AIM fully complies with ECC Directive 89/336/EEC.
• AIM is available for 3 phase systems and for 3 phase, 4 wire distribution systems (i.e. to mitigate unbalanced non-linear loads with high neutral current returns).
• AIM is available as a fully enclosed unit or as a chassis unit, for fitting into an MCC or switchboard.
• AIM compensates from 2nd to 51st harmonic. Response time ~ 100 micro-seconds, especially suitable for dynamic loads.
• AIM provides 'Global harmonic compensation' in contrast to some active filters where the harmonic compensation has be specified and programmed.
• AIM is simple to connect. Only three phases and two current transformers (3Wire AIM’s) to connect and can be retrofitted with ease to existing loads.
• AIM Filters have reliability, MTBF 10.8 years.
• The AIM filter is not effected by changes in system impedance and is inherently non-resonating.
• The AIM filter can mitigate individual or multiple non-linear loads and can be installed at equipment, motor control centre, or switchboard level.
