Acim Nidec KBWM & KBMD

<p><a href="/en/drives/control-techniques/Contact-Information">Request for Product Quote</a> </p> <p>Our off-the-shelf DC Drives provide variable speed for DC motors from sub-fractional to 2 horsepower.* They are available in 115 and 208/230 Vac - 50/60 Hz with 1Ø input and are housed in a NEMA 1 enclosure. A variety of optional accessories are also available to meet the most demanding applications.</p> <p><span>*For OEM applications, custom drives are available.</span></p> <p> </p> <h2>KBWM SCR Drive – NEMA 1</h2> <p>The KBWM series of DC drives are rated for 1/100 to 3/4 horsepower motors and are housed in a NEMA 1 enclosure. These drives are the compact version of the Multi-Drive (KBMD). This unidirectional SCR drive utilises the KBMM speed control module, which prevents motor failure due to demagnetisation. It requires a plug-in horsepower resistor to operate and includes an AC line fuse and an armature fuse holder.* This drive also contains auto inhibit which provides a smooth, safe start during rapid switching of the AC line and a terminal block to facilitate wiring. </p> <p><span>*Plug-in horsepower resistor and armature fuse supplied separately.</span></p> <p> </p> <h2>KBMD SCR Drive – NEMA 1</h2> <p>The Model KBMD-240D, also called Multi-Drive, is rated for 1/100 to 2 horsepower motors* and is an SCR drive housed in a NEMA 1 enclosure. It utilises the KBMM speed control for its electronics. It handles both 115 and 208/230 Vac line inputs by setting the built-in dual voltage switch. The single model can be used on a wide range of motor horsepower by inserting the appropriate plug-in horsepower resistor, which is required to operate this drive. It includes an AC line fuse and an armature fuse holder.** This drive also contains auto inhibit which provides a smooth, safe start during rapid switching of the AC line.</p> <p> Options: Auxiliary heat sink, forward-brake-reverse switch kit**.</p> <p><span>*An auxiliary heatsink is required when operating motors above ¾ hp at 90 Vdc and 1½ hp at 180 Vdc. <br> **Plug-in horsepower resistor, AC line fuse and armature fuse supplied separately.</span></p>
