Hammond Power WAHF1K150A-I Active Harmonic Filter 480V 150A 60Hz ETH/IP type 1

The AHF is designed to reduce total demand distortion (TDD) and total harmonic distortion (THD(V)) to less than 5%, correct linear displacement, and balance incoming three-phase current.

The AHF operates from 480, 240, or 208 VAC (±12%, -15%), 3-phase, 3-wire plus ground, with a voltage frequency of 50 or 60 Hz (±5 Hz).

The AHF efficiency is no less than 98% at full load, with heat losses not exceeding 2% of the unit's KVAR rating.

Additional units can be paralleled to achieve the required harmonic correction if the needed correction exceeds the maximum current rating of a single AHF, with up to six systems connectable in parallel.

The AHF is designed for ambient operation temperatures between 0° C and 40° C.

The AHF can operate in humidity levels from 0 to 95% (non-condensing) and up to an altitude of 1000 M (de-rated at higher altitudes).

The AHF uses two split core type current transformers on phases A and B to monitor line current. A third CT is used on phase C if line-to-neutral loads are present.

Yes, the AHF has an Ethernet communications interface for remote configuration, diagnostics, data collection, and enabling/disabling the system. It also features a remote enable/disable dry contact input.

The LCD touch screen displays power quality information (voltage, current, THD, harmonics, KW, KVA, PF), operating status, diagnostic messages, and historical data like shutdown and reset records.

AHFs rated for 50-200 amps are in NEMA Type 1 gasketed, wall-mountable enclosures. Those rated for 300 amps are in floor-mount (freestanding) enclosures.
