AHF 005/010

Installation

Description

The Danfoss harmonic filters AHF 005 and AHF

010 ensure near-sinusoidal line current minimizing

the harmonic current emission into the line supply.

The Danfoss AHF 005 and AHF 010 are advanced

harmonic filters not to be compared with traditional

harmonic trap filters. The Danfoss harmonic filters

have been specially designed to match all the Danfoss

adjustable frequency drives. The filters AHF 010 and

AHF 005 are available in four voltage ratings.

380 - 415 V AC, 50 Hz

440 - 480 V AC, 60 Hz

500 V AC, 50 Hz

690 V AC, 50 Hz

The Danfoss AHF 010 and AHF 005 have the

following characteristics:

Small compact housing that fits into a panel

Easy to use in retrofit applications

AHF 010 reduces the total harmonic current

distortion to 10%*

AHF 005 reduces the total harmonic current

distortion to 5%*

Current rating from 10A - 370A

For higher power, modules can be paralleled

One filter module can be used for several

adjustable frequency drives

High efficiency (> 0.98)

User-friendly commissioning - no adjustment

necessary

No routine maintenance required

* THiD of 10% or 5% will be achieved when the

following conditions are met:

-

THvD of the system without the drive

operating is less than 2%

-

Filter is operating at nominal load

If these conditions are not fulfilled, a significant reduction

of the harmonic components can still be achieved, but

the rated THiD values may not be achieved.
