Features: SVD series Single-phase High Precision Full-auto AC Voltage Stablizer, is a seriesof our main products which are composed of the contact type self -coupling voltageregulator, servo motor, automatic control circuit system etc. When voltageof network is not steady or the load varies, the automatic sampling control circuitsystem to makes a signal to drive the servo motor to adjust the position ofthe carbon brush in the self-coupling regulator so as to make the output voltagereach to the rate voltage.This series products has protective function of time-delay, over-voltage, under-voltageand over loadSpecifications: 1) Input voltage: 150 - 260V AC 50/60HZ2) Output voltage: 220V+/-3% or 110V+/-6% 3) Ambient temperature: -5 -404) Output over-voltage protection: AC 248V+/-4V 5) efficiency :more than 90%5) products Power: 500VA 1000VA 1500VA producing area:wenzhou china payment:T/T L/C
