【英文介绍】

The model is a 5448-89 in the SPM-D synchronizer family. The unit is equipped with standard microprocessor-based design and features. The 5488-894 provides automatic frequency and phase slip for generator control systems, utilizing analog outputs to process bias signals. Models 5488-894 are equipped with standard SPM-D power failure identification and generation protection. This includes three-phase, mains voltage undervoltage monitoring capabilities, and single-phase voltage undervoltage monitoring capabilities. Other features include frequency over/under monitoring, phase shift monitoring, then reverse and overload power monitoring.

The electrical specifications of the 5448-894 model are as follows: The measured voltage is 110v /AC, and the measured current range is 40 to 70 Hz. The operating power supply is nominally 24v /DC, but ranges from 18 to 32v /DC. The maximum power consumption is 10w. When operating, the device needs to operate at ambient temperatures of -20 to 70 degrees Celsius, and it can withstand relative humidity up to 95%. The dimensions of the 5488-894 are 144 mm x 72 mm x 122 mm and weigh at least 800 grams.
