CR Chassis Regen Reversing, DC Drives, Chassis 6
The KBMG Series of DC Drives consist of two models rated for 1/100 to 2 horsepower motors. This chassis ultra-compact, full-wave regenerative drive is capable of operating DC PM or Shunt motors in a bidirectional mode. Its 4-quadrant operation provides forward and reverse torque in both speed directions. Jumper selections include: Input AC Line Voltage, Armature Current, Motor Armature Voltage, Analog Input Voltage, Control Mode (Speed or Torque) and Coast to Stop (CTS) or Regenerate to Stop (RTS). The Overspeed Protect Circuit prevents failure of the power bridge in extreme overhauling conditions. Reliability of the KBMG is further enhanced with the use of a high speed current limit circuit and MOV Transient Protection. LEDs, which can be used for diagnostics, are provided for power on and motor overload. Power connections are made via quick connect terminals and signal input connections are made via a removable terminal block. A 5K ohm potentiometer is included. This drive also contains Auto Inhibit® which provides a smooth, safe start during rapid switching of the AC line.
Option: Auxiliary Heat Sink (P/N 9861), Bipolar Signal Isolator (P/N 8832), Multi-Speed Board (P/N 8833).
*An Auxiliary Heat Sink is required when operating motors above ¾ HP at 90VDC and 1½ HP at 180VDC.
