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
Options include: custom mounting configurations, custom IP rated enclosures, element size / shape, power, multiple resistors
in a single enclosure, etc.
For custom designs please include: duty cycle, total power and resistance and mounting requirements.

Notes
• The power rating of each bank is directly related to the number of elements in the resistor, this means the length and weight of the resistor
will vary by power rating. Please consult the table above for the relevant length and weight of the grid resistor to be quoted.
• Standard resistor banks are highlighted in bold.

Standard GRE1Jxxxxx 6500 W grid banks are rated with max. design temperature rise of 375 °C over an ambient.
Continuous Duty Application with Constant Voltage Applied to Resistor
Solid line - GRE1J8R000K00N0000 standard 6500 W, 8  resistor bank
Dotted line - GRE1JR1000K00N0000 standard 6500 W, 0.1  resistor bank
Graph shows the peak element temperature is reached between 100 s and 400 s depending on active mass of material used to achieve
the desired resistance. Different rates of heating occur depending on the active mass used in the design.
Pulse Application with Non-Constant Voltage Applied to Resistor
Dashed line - GRE1JR1000K00N0000 standard 6500 W, 0.1  resistor bank
Graph shows the peak element temperature of about 450 °C over ambient is reached with an average continuous duty temperature
of 375 °C over ambient when a continuous voltage 0.5 MJ energy pulse is applied to the resistor for 5 s once every minute, cycled
continuously. Average temperature at continuous cycling is 375 °C (peaks above and below).
