About User Manual
This document describes a backup system EBU1, it’s installation and operation. It is very important to read User Manual before
start using the system.
1. General Information
1.1 Function
EBU1 is a power supply backup device used to connect various electronic appliances, such as sensors, adapters, dialers, automation
systems and other electronic devices.
1.2 Operation Description
ELDES EBU1 power supply backup unit has an internal 9V battery which is used to power up a connected device in case of power
supply failure. The DC output voltage is the same as DC input voltage. In case of main power is lost or cut, the system automatically
activates PF (Power Failure) output connector and begins powering up the connected electronic device by internal EBU1 battery.
After the main power source restores, the system charges the internal battery with built-in battery charger. EBU1 system comes
with wires of 15cm length .
This device can be used with any electronic device, which is powered by 9V. EBU1 can be used with the following ELDES devices:
ESIM021, ESIM251, EW1, ELAN1 etc.
