Ascent’s AVR200 Series Automatic Voltage Regulator provides a stable output voltage supply for electronic equipment and is widely used in telecom base stations, CNC machines, computerized topography, printing machines, production lines, and other voltage stabilization applications.
• Wide input voltage range
• Wide load power factor range (resistive, capacitive, inductive)
• Continuous operation and short time overload rated
• Long life roller type carbon brush
• Negligible wave distortion to output
• Self-coupling transformer can be connected at the input or at the output of the DBW
• Protection circuit (over/undervoltage and overcurrent with shutdown delays)
• Vacuum pressure impregnation process for F or H class insulation of the magnetic components
• Surge protection option is available on request
• Multiple outputs or other output voltages are available on request
