SFA 400

Product catalog summary

Overview: The document provides technical specifications and details for Sine Filters, specifically the SFB and SFA 400 series. These filters are designed for use with inverters and motors to improve performance and reduce interference.

Specifications:

SFB Series: Includes models like SFB 400/4 to SFB 400/480, with varying terminal sizes, fixing methods, and weights. They are designed for vertical mounting and have specific dimensions and weights ranging from 4.0 kg to 220.0 kg.
SFA Series: Models range from SFA 400/1.3 to SFA 400/60, with rated voltages of 3 x 400 Vac and current ratings from 1.3 A to 60 A. They support motor outputs from 0.55 kW to 30 kW and have a maximum ambient temperature of 45°C.

General Data:

Rated voltage for SFA 400 is 3 x 400 Vac, and for SFA 500 is 3 x 500 Vac.
Switching frequencies are up to 8 kHz for SFA 400 and 4 kHz for SFA 500.
Insulation class is H, with a protection index of IP 20.

Advantages:

Prevents motor overvoltages and allows for long cable lengths.
Reduces motor noise, bearing currents, and leakage currents.
Minimizes line-borne and field-borne interference, reducing the need for shielded cables.
Improves drive system efficiency and extends motor service life.

Applications: These filters are used for suppressing differential and common mode interference in inverter systems, enhancing performance and reliability.

Standards and Approvals: Complies with IEC 61558-2-20, UL 508, CSA 22.2 No. 14-10, UL 5085-1/-2, and CSA 22.2 No.66.

Safety and Protection:

Metal enclosures with insulation class F.
Test voltage of 2500 Vac, 50 Hz.
Safety class I prepared.
