General Information

- Multi-Drive™ represents the latest in state-of-the-art design for variable speed DC motor controls

- The KB Electronics KBMD-240D DC Variable Speed Drive is rugged and compact in size and is able to handle both 115 and 230V AC line inputs by setting the built-in Dual Voltage Switch

- This model controls all motors through 3⁄4 Hp at 115V and 11⁄2 Hp at 230V

- 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
