HIGH VOLTAGE, AC POWER

WITH DC CONTROL

The LC-4 is a + 160 VDC high voltage control which combines the

power and availability of AC input, with the control and versatility

of DC PWM output, all in one compact unit.  You don’t need a

separate power supply.

The LC-4 family of DC brushless motor controls uses an advanced

design of PWM drive technology to produce surprisingly powerful DC

brushless motor control capability at an afford able price.

Brushless motors offer all of the advantages of DC brush type motors,

and more, such as; higher speed capability, higher efficiency, and

more power for a given frame size than their brush type equivalents.

And best of all there are no brushes to maintain, meaning reduced

maintenance and extended operating life.

This high voltage DC brushless controller is capable of four quadrant1

velocity control of a single DC brushless motor.  It offers many standard

features like remotely selectable start/stop, forward/reverse, dynamic braking,

and open or closed loop speed control via external analog signal or optional

PWM signal in put. The itergrated singe quadrant closed loop speed control

system using Hall sensor feed back is standard.

PROTECTION FEATURES

• Automatic current limiting

• MOV protection circuitry

• Over-temperature trip

• Over/under voltage trip

• Magnetically/optically isolated output stages

• Locked rotor protection

• Fused AC line

MOTOR COMPATIBILITY

The LC-4 family is compatible with any three phase WYE or

DELTA wound brushless DC motor designed to operate with

high voltage DC power and processing a minimum winding elec

trical time constant of 0.5mSec. or greater.

AVAILABLE

CONFIGURATIONS

The LC-4 series is available in two versions.  The packaged ver

sion conforms to NEMA type 1 requirements and features a pro

tective cover, heat sink, quick disconnect wiring terminations,

and diagnostic LEDs. An OEM open flame version comes with

one or more circuit boards mounted to an L-shaped aluminum

mounting base.  Optional safety cover available.  The packaged

unit has its own built-in heat sink, while the open flame unit must

be attached to a suitable heat conductive surface for proper op

eration.
