Before you start… 

 
Please take a moment and read this manual before you install the OPENUPS. 
 
Often times, rushing into installing the unit can result in serious damage  to your OPENUPS 
board, computer. 

Always

 

double check the polarity

 of your wires with a voltmeter. 

 
Introduction 

 
Thank you for purchasing the OPENUPS Uninterruptible power supply. 
 
The OPENUPS was designed to provide user specified regulated power output from a wide 
input voltage, battery backup, multi-chemistry charging and cell balancing in a single PCBA.  
 
OpenUPS features include: 
 
-USB interface, works with Windows devices (Linux API planned) 
-SMBUS slave and I2C master 
-Input between 6-30V 
-Programmable voltage thresholds, 
-Generate any output voltage between 6-24V, 
-Supports multiple battery chemistry 
-Balances up to 6 series batteries. 
-Charge voltage between 6-30V, charge current up to 3A, battery balancing up to 6 cells, 
-Coulomb counting (fuel gauge) 
-Motherboard ON/OFF pulse control*
