GE 489-P1-H1-A20-T 489 series generator management relays

GE 489-P1-H1-A20-T 489 series generator management relays

Control power supply: H1 indicates that its control power supply is a high voltage input, the specific range is 90-300 V DC, 70-265 V AC, and the frequency is 48-62 Hz.
Current input: P1 indicates that the relay is suitable for 1 A phase CT secondary power supply to measure and monitor the current situation of the generator.
Analog output: A20 represents an analog output with 4-20 mA, which can output information such as measured electrical parameters in the form of analog signals for interface and data transmission with other devices.
Other features: The relay uses an enhanced display design with a large LCD display, which can clearly display the status information of the generator, diagnostic messages, etc. It has a variety of protection functions, such as over current, over voltage, under voltage, reverse power, loss of magnetism, overheating, ground fault protection, and can also monitor harmonic distortion. In addition, it also has data recording and trend analysis functions, which can record the operating data of the generator for easy analysis and troubleshooting. The measurement function is rich, including the measurement of power factor, frequency, active power, reactive power, apparent power and other parameters. At the same time, it supports a variety of communication protocols, and can communicate with the host computer or other control systems to achieve remote monitoring and management.
