  • The control, with surface mount construction, offers the user the ultimate in reliability and performance at an affordable price
  • The controls contain a unique patented super-fast DirectFed™ current limit circuit that protects the SCR power bridge against direct shorts1
  • The reliability of the control is further enhanced with the use of high-surge, 25 A SCRs, and AC line and armature fusing2,3
  • The control is designed with exclusive plug-in horsepower Resistor® 3, which eliminates the need for recalibrating IR comp and current limit when the control is used on various horsepower motors
  • In addition, the rating of the control can be extended to 1.5 hp for controls with 90 VDC output and 3 hp for controls with 180 VDC output, by the use of an auxiliary heat sink 4
  • Selectable armature or tach feedback and adjustment trim pots for minimum speed, maximum speed, current limit, IR compensation, and linear acceleration and deceleration
  • The control includes auto-Inhibit®, which eliminates surging during rapid AC line switching
  • Pulse transformer triggering, which provides cogless operation at low speed
  • Superior noise rejection circuitry, which eliminates false starts and blown SCRs
  • Enable (normally closed) and inhibit (normally open) functions provide electronic switching of control output
  • The output voltage of the control is a linear function of the main speed potentiometer setting
  • In addition, the control can be used in a voltage following mode by supplying an isolated analog input signal to terminals P2 (+) and P1 (-)
  • The control is supplied with a factory installed 25 A at AC line fuse, a 5 kOhm main speed potentiometer and QD terminals
  • 12 A (AC), 8 A (DC) maximum line current rating without auxiliary heat sink
  • 3 hp and 1.5 hp power rating without auxiliary heat sink
