We are engaged in offering a premium quality array of AVR Control Panel. These panels are appropriate for 60 MW alternator with output instrumentation of AC Voltmeter, PF meter, DC Voltmeter and DC Ammeter with Voltage control and Power Factor control and protect against voltage variations. Our offered range of AVR Control Panel is available in standard sizes and can also be customized as per the need of the clients.
Two independent Channels. Each channel will have One Auto Channel (Close Loop Voltage Control) and one manual channel (close loop excitation current control) and one dedicated manual (having one servo controlled auto transformer, One Current limiting Choke and bridge rectifier).
