DC Controls PWM Series

Instructionguide M1740008 | Manual M1740009 Adjspeeddrives

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 ¼ 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.

Available ratings:
Enclosure Type Description Output Amps HP Range 115 Volt HP Range 230 Volt
NEMA 1 Non-reversing 3 1/40-1/8 1/40-1/4
