About the 8440-1027
Model number 8440-1027 is part of the SPM-D21/PSVX set of synchronizer modules. The SPM-D21/PSVX models are built with a combined amount of features and functions, including generator and mains circuit breaker synchronization, as well as syncing for load control and power factor control, and generator and mains protection. These units are all designed with a microprocessor as the operational base for these units.
The 8440-1027 is outfitted with automatic frequency matching, as well as voltage and phase matching capabilities. This unit is also installed with several modes for parameter adjustment, which are labeled check, run, off, and permissive.
The 8440-1027 model is capable of different operations, such as the mains parallel operations, isolated operations, and dead bus operations. The main parallel functionalities include a true RMS power calculation, a real power control, and then a soft shutdown and power factor control. The isolated functionalities are the voltage and frequency controls. The dead bus functionality handles the closing of both the generator circuit breaker and the main circuit breaker.
One of the many operating features of the 8440-1027 model is the multi-level password protection, this model also allows you to adjust the language, the adjustable languages on the control model are German or English. It is important to note that your controller can be connected via PC, if being connected via PC you operate and configure the controller through your PC connection or directly through the controller. The power supply needed to properly run your controller is 24 Vdc (plus or minus twenty-five percent).
