About the 9905-009
The 9905-009 is part of the WoodWard SPM-A Synchronizer series and comes outfitted with a standard set of WoodWard SPM-A specifications. The frequency range for this unit is a standard 50 to 60 hertz. This unit is capable of voltage matching, and has up to a 10% capacity for it, the most in the series. The phase angle that this unit is able to provide includes an amount of leeway, given a plus or minus factor of 10 degrees. In order to check the generator’s phase angle and frequency, the voltage inputs are first applied to separate signal conditioner circuits.
Each of the signal conditioners are able to change the voltage input signals’ shape so that it can be accurately measured. The 9905-009 is able to be outfitted with a user-installed switch that can control the relay driver. This switch is required to be wired to the synchronizer contact points 10 through 13. AX Control INC can and will buy, sell, repair, and resell these machines as well as all of its other products.
