Selection Guide

Choosing the right KVA of a Servo Stabilizer
a. KVA of Stabilizer = H.P. of lift * 3
b. KVA of Stabilizer = Tonnage of A.C. plant * 2
c. KVA of Stabilizer = H.P. for Resistive loads
d. KVA of Stabilizer = H.P. or K.W./ Power factor for Reactive loads.
Note : While precuring / installing servo stabilizer on mains, care should be taken and ensure that the capacity of servo voltage stabilizer is more than the maximum load
connected / Can be operated through it at any time.
