GU621A is a new generation Automatic Mains (Utility) Failure module for single Genset, which adopts bran-new outline configuration, focus on the requirements of customers, and perfectly improves the performance of controller. It fully meets the auto control requirements of different kinds of Genset for user or special assembly

factory.

l True RMS measure of voltage and current.

l Multi-language menu.

l 128 x 64 pixel LCD display.

l 4 analog inputs can be used to measure pressure, temperature, fuel level and so on; optional kinds of internal sensors and parameters are configurable.

l More configurable auxiliary control relay outputs.

l More configurable isolating digital inputs. Buttons on control panel are used for selecting control

l modes, starting and stopping the operating procedure, displaying data, and modifying the parameters. LED indicators are used for indicating the operation mode of controller and the running status of Genset, and LCD displays each measuring parameter and status.

l Flexible equipped with communication interface of RS485, RS232 or USB, realizing remote monitor or communication with PC, fully realizing functions of remote signaling, telemetering and remote control, can read and configure the operating parameters of controller.

l With GPRS-DTU or Ethernet-DTU for remote communication instead of RS485, RS232, or USB port for remote communication.

l Optional CAN bus, reading and controlling the parameters of ECU engine.

l All connections of controller are connected by pin locked up terminals,easier and more convenient to connect, move, maintain and replace the device.
