Description

The AS480 AVR made by Stamford is a half wave phase controlled AVR which forms part of the excitation system of the brushless generator. The design uses SMT (Surface Mount Technology), custom mouldings and heatsinks to create a compact and efficient AVR.
AS480 Stamford Automatic Voltage Regulator technical specifications and description
The AS480 AVR has an input voltage of 100 – 264 VAC (single phase) and operates at a nominal frequency of 50 – 60 Hz. The output voltage is 82 VDC at a power input of 200 VAC, or 45 VDC at a 110 VAC power input. The AVR outputs a continuous current of 5.0 A or a transient current of 7.5 A for 10 seconds. The resistance averages at 15 ohms per minute. Load regulation of the output voltage is +/- 1 percent, inclusive of 4 percent engine governing. The AVR allows for a thermal drift of 0.03 percent per degree Celsius change in ambient AVR temperature. The AVR offers a typical system response of 20ms, taking 80ms for field current to reach 90 percent, and 300ms for machine volts to reach 97 percent. Featuring the latest in safety measures, the AVR’s over-excitation conditions are limited to a safe period by a protection circuit within the AVR. The AS480 AVR has a set point of 67 VDC +/- 3 (fixed) and a time delay of 10 – 15 seconds (fixed) in over excitation protection. A separate overload protection system within the EBS electronic module protects the generator against sustained overloads. The environmental specifications are optimal, with an operating temperature of -40 to +70 °C, a storage temperature of -55 to +80 °C, relative humidity of 95 percent, and vibration of 55 mm/sec at 20 – 100 Hz.
Automatic Voltage Regulators for all your needs
The AS480 AVR made by Stamford has all the features of a precision-made, high quality automatic voltage regulator. The design makes provision for the connection of a remote voltage trimmer, allowing finer control of the generator’s output voltage, and the facility for droop CT connection allows parallel running with other similarly equipped generators.
