Product introduction:

GR-800 intelligent feeder terminal unit, suitable for 10KV feeder section point or demarcation point, can switch between conventional protection and local feeder automation logic function through the function button on the panel, reducing the time and scope of power outage, and achieving line fault detection, isolation and power supply restoration of non-fault area.

It provides 4G/5G wireless communication, fiber optic Ethernet, dedicated line modem, intelligent wireless communication network and other communication modes to achieve fault information reporting and real-time uploading of line equipment information. DLT634.5-101/104 and other communication protocol libraries help to achieve communication connections for various applications. It also equipped with parameter setting function to set or change local or remote control parameters. Its intelligent DC power supply to achieve dual power supply and smart management of backup lithium batteries.

Note: Technical datas and sketches are only for your reference. Such details in our contact prevail.



Features

lThe bell type and all sealed structure, and Aluminum Die Casting material guarantee the protection class to be IP67

lSuper capacitor as the working power source and lithium iron phosphate as the backup power source, such makes its effective service life up to 8 years. The batteries are located inside the bell-type enclosure.

lChinese LCD display and high brightness, even for -40 ℃ low temperature area
