This model is the 5448-89 in the SPM-D Synchronizer series. This unit is outfitted with the standard microprocessor-based design and features. The 5448-894 is able to provide the generator control system with an automatic frequency and phase slip, utilizing the analog output to process the biased signals.The 5448-894 model is outfitted with the standard SPM-D Mains Failure Recognition and Generation Protection. This includes a three phase, mains over and under voltage monitoring capabilities, as well as single phase over/under voltage monitoring capabilities. The other features include over/under frequency monitoring, phase shift monitoring, and then reverse and overload power monitoring.
The 5448-894 model has the following electrical specifications: the measuring voltage is 110 V/AC, and the measuring current ranges from 40 to 70 hertz. The operational power supply is nominally 24 V/DC, though the range is from 18 to 32 V/DC. The power consumption is 10 W at max. When operational, the ambient temperature this unit requires to function in is -20 to 70 degrees C, and the relative humidity it can withstand is up to 95 percent.The 5448-894’s dimensions measure out to 144 mm by 72 mm by 122 mm, and weighs at least 800 grams.
