LCA
LOW COST RESISTOR ASSEMBLY

PDF File

 

These economical and powerful components comprise two, three or four high power resistors
housed in partial steel covers at each end.  These rugged, powder coated covers ensure an
excellent seal.  The internal resistors use aluminum plates at each end instead of our
standard cement molding.  This innovation reduces construction time and reduces cost,
at no reduction of performance.  The major application of this exciting new model is high
power inverter braking units.
