Automatic Voltage Regulator SX460-A SX460 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator(AVR) and forms part of the excitation system for a brushless alternator. Technical specification input voltage Jumper selectable 95-132V ac or190-264V ac frequency 50-60 Hz nominal phase 1 output voltage Max 90V dc at 207V ac input Current Continuous 4 A dc Intermittent 6A for 10 secs resistance 15 ohms minimum regulation +/- 1.0% (see note) Thermal drift 0.05% per deg.c change in AVR ambient (note 2) Typical system response AVR response 20 ms Filed current to 90% 80 ms Machine volts to 97% 300ms External voltage adjustment +/- 10% with 1 k ohm 1 watt trimmer(see note 3) Under frequency protection Set point 95% Hz(see note 4 ) slope 170% down to 30 Hz Unit power dissipation 10 watts maximum Build up voltage 4 volts @ AVR terminals Environmental Vibration 20-100 Hz 50mm/sec 100 Hz 2kHz 3.3g Operating temperature -40 to + 70c Relative humidity 0-70c 95% (see note 5) Specification Normal AVR supply power: 2 auxiliary windings Shunt supply: 150V - 50/60Hz Rated overload current: 10A,10s Electronic built- in(overload, short circuit, and loss of sensing) protection: If excitation current raises over 10 Amps for more than 10 seconds, excitation current will drops automatically to about 1A. To reset AVR protection, 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 voltages taps at: Terminals 0-110V=95-140V Terminals 0-220V=170-260V Terminals 0-380V=340-520V We still supply AVR: 1.
