• 100% brand new and high quality.
• This product is a AVR(Automatic Voltage Regulator) for brushless alternator with adjustable voltage.
• The regulator monitors the exciter excitation current as a function of the alternator output voltage.
• Very simple in design, the alternator with shunt excitation has no sustaining short-circuit capacity.
• Made with flame retardant and heat resisting material, stable and reliable to use.
• Input

• Normal AVR supply power:2 auxiliary windings (X1, X2, ans Z, Z2)
• Shunt supply: 150V – 5060Hz Rated overload current:10A, 10s.
• Electronic built- in )overload, short circuit, and loss of sensing) protecting: If excitation current raises over 10 amps for more then 10 seconds, excitation current will drop automatically to about 1A.
• To reset AVR protection, the generator must be stopped )or by cutting supply voltage to the AVR). Protection of power inputs by fuses F1
• Voltage sensing: 5VA insulated transformer with input voltage taps at: Terminals 0 – 110V = 95 to 140V. Terminals 0 – 220V = 170 to 260V. Terminals 0 – 380V = 340 to 520V
