BC142 BALDOR 1/50-3HP SCR DRIVE 230VAC 180VDC CHASSIS 1-WAY

BALDOR BC142 is an adjustable single voltage speed DC Drive. It will control motors between 1/100-1.5 HP and up to(3 HP w/aux. Heat-sink optional) by inserting the proper Plug-in Horsepower Resistor®.

APPLICATIONS: Conveyors, mixers, packaging machinery and other applications requiring variable speed and constant torque.

ONE WAY SCR CONTROL

  • Full wave SCR control with free wheeling diode (NEMA type K)
  • Field power supply allows use with shunt wound DC motors as well as permanent magnet motors
  • Adjustable accel, decel, current limit, IR comp, min and max speed
  • Current limit indicating LED
  • 5K speed pot for speed control
  • Anti-demag circuit protects PM motors and helps protect the SCR power bridge against direct shorts
  • Noise rejection circuit eliminates false starts and blown SCR's
  • UL and cUL recognized

FEATURES:

  • Plug-in Horsepower Resistor®5 – Eliminates the need to calibrate control for IR Comp and Current Limit when used on various horsepower motors.
  • Auto Inhibit® – Allows the control to be rapidly switched “on” and “off” using the AC line.
  • Inhibit and Enable – Allows the control to be turned “on” and “off” using electronic switching.
  • Trimpots: MIN & MAX Speed, IR Comp, Current Limit, ACCEL & DECEL
  • Armature or Tach-Generator Feedback
  • MOV Transient Protection
  • SMT Construction
  • Power On and Current Limit LED Indicators
  • Built-in Armature and AC Line Fusing
  • Main Speed Potentiometer (5 kΩ) (included)
Dimensions: 4.30” x 3.60” x 1.30”.
