Our 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 aluminium 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 hp motors. These drives are housed in a NEMA 4X / IP65 die-cast aluminium washdown/watertight enclosures for indoor or outdoor use. The exclusive short circuit and timed current limit (TCL) circuitry prevents motor burnout and demagnetisation 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 and it is not auto-reversing.

Options: Signal isolator, ON/OFF AC line switch, run-stop-jog switch, auto/manual switch, forward-brake-reverse switch*, anti-plug reversing module*.

*Not for use with model KBPC-225D.

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 hp, 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 Ω potentiometer is included.

Options: IRC bipolar signal isolator, KBRC forward-stop-reverse switch, On/Off AC line switch, KBRC auto/manual switch.
