VLT Advanced Active Filters

A flexible and adaptable solution for central or de-central harmonic mitigation. Danfoss advanced active filters can compensate for individual VLT drives as a compact integrated solution or can be installed as a compact standalone solution at a point of common coupling, compensating for multiple loads simultaneously. Danfoss active filters can operate at medium voltage level by means of a step-down transformer.

Voltage range

• 380 – 480 V AC 50 – 60 Hz

Power Range

• 190 A, 250 A, 310 A, 400 A, 500 A.
• IP 21/NEMA Type 1
• IP 54/NEMA Type 12

VLT Advanced Harmonic Filters

The danfoss advanced harmonic filters have been specially designed to match the danfoss frequency converters. The solution is available in two variants, AHF 005 and AHF 010, connected in front of a danfoss frequency converter, the harmonic current distortion generated back to the mains is reduced to 5% and 10% total harmonic current distortion at full load.

Features:

• Electrically matched to the individual VLT® FC-drives >98% efficiency
• Side-by-side mounting with VLT®
• Design based on proven VLT® technology and components
• Optimized for mounting in panels
• Easy to use in retrofit applications
• Easy commissioning
• Robust solution that requires no routine maintenance
• IP 00 and IP 20 (IP 21/NEMA 1 kit optional).
