Neuron Battery Backup

The Neuron Ethernet Gateway Battery Backup is a power solution designed specifically for use with the Neuron Ethernet Gateway in an industrial environment. It contains a LiFePO4 cell that provides an uninterruptable power supply for the gateway in the case of a mains power loss or otherwise unreliable power.

Experience how easy it is to get started and the huge benefits of our simple and practical IoT solutions.

General Description

The Neuron Ethernet Gateway Battery Backup is a reliable and robust power solution designed for use in industrial environments. The system is specifically tailored for use with the Neuron Ethernet gateways and is ideal for providing backup power in situations where the main power source is lost or unreliable.

The LiFePO4 battery chemistry offers several advantages over traditional lead-acid batteries, including a longer service life and a lower self-discharge rate. The battery backup system contains several safety features shutting down power if an overcurrent, undervoltage or overtemperature event occurs.

The system is DIN-rail mountable, making it easy to install in industrial control panels. It also features a communication interface*, allowing the Ethernet Gateway to manage and monitor the battery backup.

Principle of Operation

When the main power source is present, the LiFePO4 battery is charged by an on-board charger. In the event of a power loss, the Ethernet Gateway will automatically switch over to the battery backup. The onboard charger monitors the battery’s state of charge*, temperature and current, and will prevent overcharging, overdischarging and short-circuiting.

Before installing make sure the power to the Neuron Ethernet Gateway is turned off.

The device has a DIN-mounting capability which means it can be easily installed in a control panel or enclosure by sliding it onto a 35mm standard DIN rail and connecting it to the Neuron Ethernet Gateway’s back bus connector.

You can now apply power to the Neuron Ethernet Gateway and press the button on the front side to enable the battery backup.

The Battery Backup can be connected to the Ethernet Gateway on both left and right side.
