KBMD-240D KB ELECTRONICS 11AMP NEMA1 SCR SPEED CONTROL 115/230VAC 1-WAY 9370

Direct replacement for the BALDOR BC140

NEMA1 Packaged single direction SCR drive in a NEMA-1 enclosure. It utilizes the KBMM™ speed control for its electronics. It handles both 115 and 230VAC line inputs by setting the built-in Dual Voltage Switch.

KB Multi-Drive™ represents the latest in state-of-the-art design for variable speed DC motor controls. It is rugged and compact is size and is able to handle both 115 and 230V AC line inputs by setting the built-in Dual Voltage Switch. In addition, the single model can be used on a wide range of motors by selecting and inserting the appropriate Plug-in Horsepower Resistor®.
The standard model, KBMD-240D, controls all motors through 3⁄4 Hp at 115V and 1.5 Hp at 230V. By installing the KB Auxiliary Heatsink, the horsepower range is increased to 1 Hp at 115V and 2 Hp at 230V. The versatility of the control is enhanced with the optional Forward-Brake-Reverse Switch Kit.
The electronics for the Multi-Drive™ consists of KB’s patented KBMM™ speed control module. Its field-proven reliability is confirmed by over 100,000 controls presently in operation. The KBMM™ module is housed in a rugged metal (not plastic, like other inexpensive drives) enclosure. Keyhole slots facilitate mounting while a readily accessible terminal block simplifies wiring. Included with each control is a detailed instruction and user manual.

OPTIONAL FEATURES

• Auxiliary Heatsink (P/N SC-9861). Extends control rating to 1 Hp at 115V and 2 Hp at 230V
• Forward-Brake-Reverse Switch (P/N SC-9860). Includes switch and prewired dynamic brake resistor.

STANDARD FEATURES:

• Plug-in Horsepower Resistor®s. Allows a single model to be used on a wide range of motors
• Dual Voltage Switch. Used to select AC line voltage operation of 115 or 230V.
• Built-in AC Line Fuse
• MOV Transient Protection (20 JOULE)
• Trimpots: MIN, MAX, IR, CL, ACCEL, DECEL s PHR Supplied Separately
