General
DK6-Y distribution automation station terminal is a new generation of microcomputer station terminal based on Blackfin embedded operating system, DSP digital signal processing technology, and network technology, which integrates telemetry, remote signaling, remote control, fault detection, communication management, and other functions. It is suitable for multi-loop centralized monitoring applications such as switching stations, boundary rooms, power distribution rooms, box transformers, and shutters. Through optical fiber, GPRS, and other channels, it can cooperate with the substation and master station of the distribution automation system to realize automatic functions such as operation status monitoring, fault identification and isolation, and automatic power supply recovery of the distribution line.

Main Technical Parameters
1) Power performance
The device power supply can accept AC and battery DC power supply modes at the same time; Under normal conditions, it is the AC power supply mode. Once the AC power supply is interrupted, the device will automatically switch to the battery DC power supply mode when there is no movement; When the AC power supply is restored, the device will automatically switch back to the AC power supply mode. The device works normally during switching. AC input has a status indicator and remote signaling.
2) The vegetable can realize the status monitoring of the power supply. The power module has an obvious indicator light and can upload the power supply status to the superior system in a letter way; It includes the AC state, whether the battery is under voltage, and the battery maintenance state (battery activation).
3) Input voltage range:
220V 20%AC
40V ~ 55V DC / 20V ~ 28V DC.
