BC142-6 BALDOR 16 Amp SCR 115/230VAC Chassis Drive 90/180VDC Output 1-Way

BALDOR BC142-6 is an adjustable single voltage speed DC Drive. It will control motors between 1/100-1.5 HP and up to (3HP 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.

• 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)
