OVERVIEW

Vishay Milwaukee resistor offers a complete line of custom and standard grid resistors (GRE1 and GRE2), also know as steel

grid, punched grid and plate resistors. With a robust all welded construction, Milwaukee resistor grid resistors are designed

using stainless steel resistance elements to absorb high energy pulses, repeatedly.

APPLICATIONS OF GRID RESISTORS

Dynamic Braking

Harmonic Filters

When an electric motor driven load is being decelerated, the

motor acts as a generator, converting kinetic energy of the

load to electrical energy. The dynamic braking circuit

converts this electrical energy into heat to slow the load,

through the use of dynamic braking resistors. Braking

resistors ensure proper motor operation, allow heavy loads

to stop quickly and protect the drive from damage.

Furthermore, dynamic braking resistors that are improperly

cooled, incorrectly sized, physically damaged or electrically

failed can cause costly unwanted down time.

Within a harmonic filter installation the filter resistors are

used to dissipate unwanted harmonic frequencies as heat.

Load Banks

Custom designed resistive load banks allow for load

simulation of many electrical applications for testing

purposes.

CONTACT THE FACTORY FOR CUSTOM DESIGN AND OPTIONS FOR STANDARD DESIGN
