DC Controls - PWM
Pulse Width Modulated (PWM) controls are available in NEMA 1 and chassis style units for sub-fractional HP frame motors from 1/40 HP through ΒΌ HP. Due to their improved form factor, these PWM controls result in quieter operation, lower operating motor temperatures, longer brush life and greater motor overload capacity than for the same motor on an SCR type control.
