EMC/EMI FILTERS

We supply a wide range of EMC/EMI Filters from Block and Roxburgh.

KMFA – High Performance for Drive Applications

This three phase range offering high performance is designed for all drive applications including servo, inverter and motor drives. The filters are economically priced and lightweight with side mounting and IP rated terminal blocks.

Typical applications  include: Machine tools, UPS, industrial controls,  process  controls,  servo, inverter,  motor  drives  and mechanical handling equipment.

IHF4 – Three Phase & Neutral Mains Filters

Low leakage is offered with medium performance for general purpose filtering with this three phase and neutral range. 
Typical applications include: Industrial equipment, machine tools,  process  automation,  power  supplies  and  high  power office equipment.

MIF3 – Multi-Stage Drive Filters

Providing very high performance, this MIF3 range of three phase industrial multi stage filters are suitable for drives where long cable length is required between drive and motor (above 50m). 
Typical applications include: Motor drive inverters.

MDF3 – Industrial Motor Drive Filters

High performance is offered with this three phase filter range which is designed for inverter/servo drives and high noise environments. Seven product variations are offered with current ratings up to 100 Amps and include stud termination.

Typical applications  include: All applications without a neutral conductor where leakage current is not a limiting factor i.e. permanently wired-in equipment (3 wire systems).

RES Chassis Filters Range

The new chassis filters encompass general purpose and single phase industrial applications and are suitable for machinery, household equipment, building automation and more. They are also well suited to noisy environments where an increased filter performance is required and dependent on selection, have both high common and differential mode attenuation

RES10 – General purpose
RES20 – High differential mode
RES30 – High performance
RES60 – High differential and common mode
RES70 – High differential, common and frequency attenuation
RES80 – Multi-stage, high performance 
RES90 – Very high performance

These are an example of a few product we offer from Roxburgh.

Passive EMI filters from BLOCK are used to suppress the electromagnetic interference between the network and frequency inverter in the frequency range between 150 kHz and 30 MHz. They ensure compliance with the limit values required under residential and industrial standards.
In the line filter design, the passive EMI filter can also be combined with a line reactor, which also reduces low-frequency interference (harmonics).

Overview:

◼︎  Attenuation of radio interference voltages >=150 kHz
◼︎  Compliance with the limit values required under residential and industrial standards
◼︎  Flawless operation of 30 mA/300 mA ground fault circuit breakers through the use of low-leakage current filter solutions
◼︎  Increased interference immunity for the system
