The Model SL15U Minarik adjustable speed control is a full wave,
solid state device that is designed to control and vary the speed of
Bodine 1/70th and 1/50th HP, 115 VDC shunt wound motors. The
control has choke/capacitor filtering to assure the controlled motor
will be extra quiet, smooth and cool running. In a typical application
2% base speed regulation is provided with the help of temperature,
line voltage, and IR compensation. The control features a speed
range of 25:1, adjustable IR compensation, and a maximum speed
adjustment to limit high speed operation. The Model SL15U Minarik
adjustable speed control is a U.L. (Underwriters Laboratories)
recognized component, File E35603.
