This device is a part of the Woodward Inc.-developed series of products. It is listed as the 2301D-EC Load Sharing and Speed Control module, a unit designed for generators that are powered by either diesel or gas engines. The 2301D-EC models are built with a microprocessor-based design, which runs the base functions of speed control and load sharing.
The 8273-507 is designed with an integrated Modbus module and rated to function in ordinary, temperate locations. The temperature extremes that this unit can withstand while remaining operational range between -40 to 70 degrees Celsius, or -40 to 158 degrees Fahrenheit. While in storage, the range is extended to -40 to 105 C, or -40 to 221 F.
The 8273-507 is designed to operate on a nominal intake of 24 volts of direct current, though the operational range is from 18 to 32 V/DC. The input supply current is nominally at 431 milliamperes, while the overall range is from 589 mA to 319.6 mA. The power consumption of this unit is at max, 20 watts while at optimal operating capacity. The 8273-507 model has a magnetic pickup rating between 100 to 25000 Hertz, at 300 to 3600 rotations per minute. The current transformer burden is less than 0.1 VA per phase.
