Filters clean up nonlinear loads
Harmonic filter modules reduce distortion, RMS and peak currents to acceptable levels.
In today's world of ever-increasing demand for more sophisticated control systems, engineers make use of variable frequency drives, switching power supplies and other nonlinear loads These are creating the increasing problem of harmonic distortion on the power grid

Modules reduce harmonic distortion
Harmonic filter modules designed to reduce harmonic distortion, RMS and peak currents to acceptable levels.
Block's newly developed HFM line of harmonic filter modules is designed to reduce harmonic distortion, RMS and peak currents to acceptable levels.
The current waveform of such nonlinear loads is improved to a near sinusoidal form.
Without such filters, uncontrolled symptoms can lead to system failure and downtime.
Block's HFM filter modules offer an economical solution from 4 to 630kW with various performance levels to meet today's advanced applications.
These filters are designed to meet European and US guidelines EN6100-3-4, EN61000-3-12 and IEEE519.
When compared with conventional methods, Block's HFM filter offers a 40% reduction in cost and sise.
The integration is similar to the well-known Block line reactor prior to the six-pulse bridge and can be supplied for new and existing controls.
To be used in the global marketplace, these filters are designed to meet safety approvals as outlined by UL508, VDE0570 and EN61558.
