    AX 050 AMP 480 VOLT

    Download instruction manual for Braking Module LG Series - Powerohm

    AC variable frequency drives are commonly used with various types of motors to form reliable variable speed drive systems. Problems with these drive systems can occur when an application requires a deceleration rate faster than what can be managed by the drive alone, or when motor speeds exceed the synchronous speed set by the output frequency of the drive (which is called an overhauling load condition). Both of these conditions create regenerated power which flows from the motor back into the drive, causing its DC Bus to rise. To manage the regenerated power and avoid shutting the drive down due to an over-voltage trip, this power must be dissipated by an external braking resistor.

    PowerOhm Series UBU Braking Modules can be used in conjunction with any AC drive to monitor the DC bus of the drive and activate an external braking resistor as needed not only to avoid over-voltage trips, but to greatly improve the performance of the drive system. The use of Braking Modules and resistors increase the braking torque capability of a variable frequency drive, allowing faster and more co ntrolled deceleration times.
