Product description
The 489-P5-LO-A20 is a microprocessor controlled device that monitors the important parameters of the generator, such as voltage, current, frequency, etc., and according to the preset protection logic, sends an alarm or initiates the corresponding protection action in case of failure.

Main function
Protection function: provides over voltage, under voltage, over current, under current, stall, overspeed and other protection functions.
Control function: With multiple output relays, can be used to control the generator start, stop, excitation, etc.
Measurement function: It can measure various parameters of the generator and provide analog output.
Communication function: It can be connected with other devices through various communication interfaces to achieve remote monitoring and control.
