UPS Configuration (CY54-04 Model)
UPS Properties
Because the TRTC Series UPS can be used with any battery, the following procedure
enables you to have the best estimate of the battery capacity possible for each site
tested. The estimated battery capacity is based on the battery's DC voltage as it
decreases when the UPS is in battery mode. Battery capacity is a chemical reaction and
is not linearly proportional to battery voltage. Therefore, the actual battery capacity may
differ.
IMPORTANT ITEMS:
1. Use a multimeter can retain a minimum DC voltage reading. It is critical when
measuring the Battery Low Voltage (AC Power Failed) DC voltage.
2. Do not copy the settings from one site to another. The number of times the batteries
were cycled (used), battery age, and different loads affect each site's settings.
3. Actual battery capacity may differ from the estimated battery capacity.
4. It is vital to run additional backup time tests to correlate battery capacities to backup
times.
Battery Full Voltage (AC Power Normal)
is the measured voltage when the UPS is in
online/Normal Mode
When the UPS has been online long enough to charge the batteries fully, and the
battery voltage has stabilized, measure the battery voltage of the entire string of
batteries using the two Battery Voltage Test Points built into the UPS. This voltage level
is considered as a 100% Point.
