About the 8440-1029
The 8440-1029 controller is part of the SPM-D21/PSVX series. These units have a microprocessor-based design and are intended for use with three-phase AC generator units, equipped with a compatible set of speed control and automatic voltage regulator modules. The SPM-D21 lineup can provide a compact device with a combination of multiple functionalities. This includes both a generator circuit breaker and a mains circuit breaker, as well as load control and power factor control module, and protection for generator and mains systems. The 8440-1029 unit is categorized as an SPM-D21/PSVX unit.
The standard SPM-D21 frame is given to the 8440-1029, built with the same dimensions and protective rating. The front-facing side of the unit has a rating of IP42, while the back is rated at IP24. The measurements of this model give it a length of 144 millimeters (5.66 inches), a height of 72 mm (2.83 in), and then a depth of 122 mm, or 4.8 in.
The standard weight for this series is approximately around 800 grams or 1.76 pounds. The 8440-1029 synchronizer is designed with up to four different modes of operation, all dealing with different methods of parameter adjustment. This model is installed with different sets of operation features, such as the mains parallel operations, which include both real power control and a true RMS power calculation ability.
