9907-028 Technical Specifications

Intro The 9907-028 is a Woodward SPM-A synchronizer designed to help match generator speed and phase prior to paralleling with other devices. This model has a frequency of 50/60Hz, a phase angle of +/-10 degrees, and lacks voltage matching capabilities. Some key features of this unit are its automatic circuit breaker closure and synchronization of generators, selectable match-up time and output impedance, and adjustable dynamics. Additional Features The 9907-028 is compatible with other Woodward units like the 2301 series, 2301A series, EPG series, and 2500 series. The user-installed switch will allow for mode switching between the four possible states of OFF, RUN, CHECK, and PERMISSIVE. RUN mode is useful for operating the 9907-028 in normal conditions for synchronization and breaker closure signals. The unit will synchronize the devices while checking for a breaker closure signal to activate the lockout circuit. CHECK mode is useful if you would like normal synchronization functionality, but do not want to permit breaker closure signals. PERMISSIVE mode restricts synchronization from affecting engine speed. Technical Information The input voltage for the 9907-028 is rated at 115 or 230VAC RMS for bus and generator at the frequency of 50/60Hz. The tolerance of this voltage is +/-10% of these values. The unit itself consumes no more than 5W of power. This unit weighs approximately 2.2kg (5lbs) and is installed in a mount with a switch gear. The maximum tolerable temperature range for operation of this unit is -45°C to 70°C. The optimal range of temperatures for operation is between 10°C and 30°C.
