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
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.

The Multi-Drive™ can be converted to the higher rating by installing KB’s Auxiliary Heatsink.
The Multi-Drive™ must be set for either 115V or 230 VAC line voltage input by setting the Dual Voltage Switch to “115” or “230”.When the control is set
for “115”, use only 90 – 130 VDC rated motors.When the control is set for “230”, use 180 VDC rated motors.
Field Voltage is 100 VDC with 115 AC line input, and 200 VDC with 230 AC line input.
