Hi there! you need a servo voltage stabiliser that uses a dimmer on the phase connection to correct the incoming mains. The DC Motor driving the arm of the dimmer is controlled by the error amplifier that Drives a servo motor to correct the incoming mains. Such SCVS are commonly used in all sensitive installations and based on applications variety of designs are available. Here in India these are mass produced and conform to reasonable quality. ----- Original Message ----- To: Multiple recipients of list CHIPDIR-L <[EMAIL PROTECTED]> Sent: Friday, November 28, 2003 7:39 PM
