Increase Reliability of Electronics: Likewise, an “electrical” shock absorber-3-phase Inductor– can increase the reliability of electronics equipment on A.C. 3-phase lines having abnormal “noise”, “line spikes”, “surges”, “hard lines”, “black outs”, “brown outs”, etc.
Simple & Inexpensive Solution: With 3-phase
inductors it is possible in many cases to “shock absorb” many of destructive processes in a simple and inexpensive manner.
Compact & Effective: Inductors are small, light and less expensive than alternate protection methods such as 100% transformer isolation. The destructive pulses are absorbed in the creation of a magnetic field in the device effectively “smoothing out” what would have been a large spike of voltage/current.
Increase Reliability in any Condition: On multi-motion systems it is necessary to protect the input of each variable speed drive separately — a single unit for all motions (unless always running together) is not useful. In certain conditions when large distances between the variable speed drive and the motor are present, an inductor may be used on the drive output (call). Inductors can also b
