CELLWATCH ®
A
state-of-the-art battery monitoring system designed specifically
for large (three-phase) UPSs, Powerware CELLWATCH utilizes the latest
fiber optic technology to provide rapid, noise-free  transmission
of information. The modular system continuously monitors the entire
battery system; including string and cell level voltage, internal
resistance, current and temperature throughout the charge, discharge,
and float periods.
Powerware CELLWATCH provides immediate warnings of deterioration
and imminent failure of batteries, and identifies any individual
battery that exhibits problems—providing a proactive approach
to ensuring UPS reliability. In addition, this monitoring system
allows battery replacement to be based on the battery’s condition,
not simply on how long it’s been in use, helping avoid premature
and unnecessary replacement.
•
Measures Voltage on each cell, either 6 or 24 times per day. The
software records data for graphical presentation during THAT day
as well as average data for historical analysis or trending. Also
compares this data continuously with high and low alarm settings
for alarm activation.
• Measures Internal Resistance on each cell, either 2 or 4
times per day. The software records data for graphical presentation
during THAT day as well as average data for historical analysis
or trending. Also compares this data continuously with high and
low alarm settings for alarm activation.
• Measures the temperature of either the battery room ambient
or a 'pilot' cell. Records this figure for graphing as well as comparison
with high and low alarm setting for alarm activation.
• Measures discharge current from a battery string and compares
the data with a discharge alarm limit set in software. In the event
of a discharge, rapidly records all cell voltage data as the battery
discharges for later identification of weak cells under load.
• Supplied with dedicated computer running Windows 98/ME/2000
software and CELLWATCH proprietary application for reporting, recording
and data analysis.
• The system is modular, so if your needs change, CELLWATCH
can be reconfigured or expanded.
• CELLWATCH is a Global product, with manufacturing both in
the USA and in Europe.
• Low voltage DC components. Measurement components never
see greater than 48v nominal DC so battery connections are all low
voltage. Electrical isolation is achieved by plastic fiber optic
cable.
