KB Electronics, Inc. continues to dominate the fractional to 5-horsepower DC Drive Speed Control market. While DC motors and drives offer the user the ultimate in high performance, small size and low cost, small AC motors and drives are challenging that very concept. KB's goal was to develop a line of AC Drives that would and could replace DC controls. Today KB manufactures AC Drives that match the performance of DC drives but fit within the same footprint or are smaller than their DC counterparts.
Many Penta-Power products contain the patented KBMM current limit circuit, other products feature current feedback loops with motor burnout protection. KB Electronics PWM controls are short circuit proof and prevent high speed runaway. Spec-Tech offers KB controls to satisfy your most demanding requirements.

AC Motor Controls - Inverters

KBAC KBAC Data Sheet

The KBAC Series of VFDs consist of 5 inverter models ranging from 1/8 through 5.0 horsepower housed in heavy duty, NEMA-4X (IP-65) die cast aluminum washdown/watertight enclosures for indoor or outdoor use. These analog style AC Drives do not require programming. Jumper selectable functions and simple trimpot adjustments make the KBAC Series quick and easy to use.

KBMA

The KBMA Series of VFDs consist of 2 inverter models rated from 1/8 through 1.0 horsepower housed in a NEMA-1/(IP-40) aluminum enclosure. The KBMA-24DF contains a built-in AC line Class A RFI/EMI filter. Jumper selectable functions and simple trimpot adjustments make the KBMA Series quick and easy to use.

KBDA

The KBDA Series of Digital VFDs consist of 5 inverter models ranging from 1/8 through 5.0 horsepower housed in heavy duty, NEMA-4X (IP-65) die cast aluminum washdown/watertight enclosures for indoor or outdoor use. Digitally programmable, all similar functions are presented in common groups making these Adjustable Frequency Drives easy to install and operate.

KBVF

The KBVF Series of Adjustable Frequency Drives consist of 13 models ranging from 1/10 thru 5.0 horsepower. These chassis/IP-20 style Drives are ideal for OEM applications where digital programming and displays are not required.

DC Motor Speed Controls

KBIC

The KBIC Series of DC Drives consist of 10 OEM & 6 Distributor models ranging from 1/100 thru 3.0 horsepower. These DC motor speed controls were first introduced in 1979 and are still one of the most reliable basic DC drives used in thousands of applications around the world.

KBMM

The KBMM Series of DC Drives consist of 3 OEM & 3 Distributor models ranging from 1/100 thru 3.0 horsepower. These DC motor speed controls were introduced in 1985 as the ultimate in reliability and performance.

KBCC-240D

The KBCC-240D chassis SCR speed control provides the same electrical features as the KBPC enclosed control. These include jumper selectable voltage adjust, current rating and feedback type, along with adjustable jog, speed/torque mode and three wire start stop.

KBCC

The KBCC Series of chassis SCR controls consist of two models rated from 1/100 thru 3 HP. Each model consists of a KBMM chassis speed control mounted to a 7" Heatsink assembly and coupled to the Barrier Terminal Kit.

KBCC-R

The KBCC-R Series of chassis SCR controls are similar to the KBCC Series, but with the addition of an Anti-Plug Reversing Module. They provide variable speed motor control, along with relay reversing, electronic dynamic braking and an anti-plugging circuit.

KBMD

The KBMD, also known as our "Multi-Drive," can be used with motors from 1/100 thru 2 horsepower and is housed in a NEMA-1 Aluminum enclosure. A unique feature of the KBMD allows it to operate a 90 VDC motor from either 115 or 230 VAC making it universally acceptable.

KBWM

The KBWM Series of NEMA-1 aluminum enclosed DC Drives is available in 2 models from 1/100 thru 3/4 horsepower.

KBMG

The KBMG Series of four-quadrant regenerative DC Drives consists of 2 models range from 1/50 thru 2.0 horsepower. These ultra-compact, chassis/IP-20 style drives are ideal for OEMs.

KBPB

The KBPB Series of SCR DC Drives range from 1/100 thru 3.0 horsepower. These compact, chassis style drives are ideal for applications requiring occasional reversing with solid-state dynamic braking.

KBRG

The KBRG Series of four-quadrant regenerative DC Drives range from 1/10 thru 5.0 horsepower. These chassis style drives are ideal for OEM applications requiring repetitive reversing with regenerative braking.

KBPC

The KBPC Series of SCR DC Drives consist of 2 models ranging from 1/50 thru 3.0 horsepower, housed in heavy duty NEMA-4X (IP-65) die cast aluminum, washdown / watertight enclosures.

KBRC

The KBRC Series of four-quadrant regenerative DC Drives consists of 2 models ranging from 1/10 thru 2.0 horsepower, housed in heavy duty NEMA-4X (IP-65) die cast aluminum washdown / watertight enclosures.

KBPW

The KBPW Series of PWM DC Drives consist of 2 models ranging from 1/50 thru 1.5 horsepower, housed in heavy duty NEMA-4X (IP-65) die cast aluminum, washdown / watertight enclosure.

KBPI

The KBPI Series of SCR DC Drives consist of 2 models ranging from 1/6 thru 2.0 horsepower, housed in heavy duty NEMA-4X (IP-65) die cast aluminum washdown / watertight enclosures. These analog style DC Drives are ideal for indexing applications.
