Automatic Voltage Regulator AVR CF-12A for Generator Alternator

An automatic voltage regulator will stabilise the voltage output on a generator as the load changes on start up and running. The first units used were electromechanical systems but modern units are solid state devices. The AVR is a feed back control system that measures the output voltage of the generator and compares it with a set point. When this varies it generates an error signal that is used to adjust the excitation of the generator. As the excitation current in the field winding of the generator increases the terminal voltage also increases. This allows for a high level of control in the output voltage.

Features of the CF12 AMP UNIVERSAL AVR:
This unit has a 220/440 VAC programmable input with a rugged compact design. It has a soft start voltage ramping to allow gradual and equal increase in power. There is an under frequency roll off protection and EMI suppression. A built in high capacity 10 Amp fuse is easily accessible for quick replacement. The sensing input voltage is 110 / 220 / 400 VAC, single phase 2 wire. The power input voltage is 100 – 260 VAC. single phase 2 wire. Maximum output voltage is 90 VDC at 240VAC input. Current continuous 3 Amps with intermittent 5 Amps for 10 seconds. The minimum resistance is 15 Ohms with a maximum 100 Ohms. The operating temperature is between -40 degrees Celsius up to a maximum of 60 degrees Celsius. The storage temperature is from -65 degrees Celsius up to a maximum of 85 degrees Celsius. The unit power dissipation is a maximum of 8 Watts.
