Chassis IP-20

KB standard off-the-shelf DC Drives provide variable speed for DC motors from sub-fractional to 5 horsepower.* They are available in 115 and 208/230 VAC-50/60 Hz with 1Ø input. These NEMA 4X / IP65 drives are housed in a rugged die-cast aluminum enclosure with a hinged cover.

A variety of optional accessories are also available to meet the most demanding applications.

*For OEM applications, custom drives are available.

KBPC SCR Drive – NEMA 4X / IP65

The KBPC Series of DC Drives consist of four models and is rated for 1/100 to 3 horsepower motors. These drives are housed in a NEMA 4X / IP 65 die-cast aluminum washdown/watertight enclosures for indoor or outdoor use. The exclusive Short Circuit and Timed Current Limit (TCL) circuitry prevents motor burnout and demagnetization of PM motors. Features, such as a selectable motor current, eliminates unnecessary calibration the of IR and CL trimpots. Other selectable features are: Input Voltage, Output Voltage, Current Range, Input Signal, Armature or Tachometer Feedback, and Tachometer Voltage. Trimpot adjustments include: MIN, MAX, ACCEL, DECEL, IR, CL and TCL. Standard features include an Armature fuse, Electronic Start-Stop, and diagnostic LED Indicator Array for “power on”, “stop” and “overload.” This drive also contains Auto Inhibit® which provides a smooth, safe start during rapid switching of the AC line.

The KBPC-225D contains all of the features of the KBPC-240D except it does not contain an Armature fuse.

Options: Signal Isolator (P/N 9431), ON/OFF AC Line Switch (P/N 9341), Run-Stop-Jog Switch (P/N 9340), Auto/Manual Switch (P/N 9377), Forward-Brake-Reverse Switch (P/N 9339)*, Anti-Plug Reversing Module (P/N 9379)*.

*Not for use with model KBPC-225D.

KBPW PWM Drive – NEMA 4X / IP65

The KBPW-240D DC Drive is a Pulse-Width Modulated (PWM) control housed in a NEMA 4X / IP 65 washdown/watertight enclosure for indoor or outdoor use. It is designed to operate Permanent Magnet and Shunt Wound motors from 1/100 to 2 horsepower. PWM provides high motor efficiency, whisper quiet operation along with less motor heating. This allows for a smaller, less costly motor to be used in most applications. A unique feature of the KBPW-240D is its active bridge, which substantially reduces the AC line surge current during cycling of the AC line. This allows the control to be turned on and off rapidly without damage to critical components. The active bridge is coupled with a failsafe circuit that will shut down the control if the main power transistor shorts, preventing a dangerous high-speed runaway condition. Motor burnout is prevented with the Timed Current Limit circuit (TCL). This drive also contains Auto Inhibit® which provides a smooth, safe start during rapid switching of the AC line.

Options: Signal Isolator (P/N 9431), ON/OFF AC Line Switch (P/N 9341), Run-Stop-Jog Switch (P/N 9340), Forward-Brake-Reverse Switch (P/N 9339), Anti-Plug Reversing Module (P/N 9379). 

KBRC SCR Drive “Regen Reversing” – NEMA 4X / IP65

The KBRC-240D DC Drive is a Full-Wave Regenerative Drive housed in a NEMA 4X / IP 65 washdown/watertight enclosure for indoor or outdoor use. It is designed to operate Permanent Magnet and Shunt Wound DC motors from 1/100 to 2 horsepower, in a bidirectional mode. It has 4-quadrant operation, which provides forward and reverse torque in both speed directions. An important feature, Timed Current Limit (TCL), provides motor burnout protection. The KBRC-240D can be operated from a two or three wire start/stop circuit or can be started from the AC line. A set of dedicated normally open or normally closed relay contacts are provided, which are activated via the start/stop circuit. Main features of the KBRC-240D include speed or dual torque control modes. In addition, Regenerate-to-Stop (RTS) or Coast-to-Stop (CTS) modes can be selected. This drive also contains Auto Inhibit® which provides a smooth, safe start during rapid switching of the AC line. A 5k ohm potentiometer is included.

Options: IRC Bipolar Signal Isolator (P/N 8842), KBRC Forward-Stop-Reverse Switch (P/N 9485), On/Off AC Line Switch (P/N 9486), KBRC Auto/Manual Switch (P/N 9487).
