For applications that require faster deceleration rates, or where motor speeds are exceeding the synchronous speed set by the output frequency of the drive (an overhauling load condition) viz. Lifts & Elevators, Cranes, Conveyors, etc., a braking resistor is required. The purpose of a dynamic braking resistor is to slow down or to quickly stop a motor by draining excess voltage and keeping it within safe tolerances.

Lifts & Elevators, Cranes, Conveyors, etc., a braking resistor is required. The purpose of a dynamic braking resistor is to slow down or to quickly stop a motor by draining excess voltage and keeping it within safe tolerances. Braking resistors increase the braking torque capability of a variable frequency drive, producing faster and more controlled braking.

Input reactors are used between variable speed drives and utility. They're used to dampen the harmonic content and rush of the current drawn by the motor drive. Line Chokes are used to protect your drive from harmful line disturbances. Our reactors help prevent equipment failure and down time & can add years to the life of your Drive.

Detuned Filter Reactors are used in series with capacitor banks in power factor correction units. By using these types of detuned reactors it is possible to avoid the following negative effects on the system: Overcurrent during switching on the capacitor banks Incidental resonance of Capacitors along with stray inductance

D.C. Chokes are used at the input end of D.C. Drives to protect Input Rectifiers from harmonics, voltage transients, surges etc. on the power line.
