KB offers 4 models of NEMA 1 Variable Frequency Drives in two categories. The KBMA models use analog displays and the KBMK models use digital displays. All 4 models are digital drives and use the same logic and power circuits.  The differences between them are:

1. The KBMA models use a potentiometer to set motor speed and trimpots make the most common adjustments - min and max speed, accel, decel, CL and slip comp.
2. The KBMK models use digital keypads with displays to set over two hundred programmable functions.

Both models are enclosed in a sturdy, stamped aluminum enclosure.

KB NEMA 1 AC Drives are available through over 800 distributor’s world wide. Please use our Distributor Search (located on the right menu) to find a supplier near you.
