Three-Phase Uninterruptible Power Supply
(UPS) for Emergency Lighting Applications
The TreStar 924 offers three phase uninterruptible power
supply (UPS) central emergency lighting systems for 10 - 75kW applications.
The TreStar 924 is a true, on-line, double-conversion UPS built to
withstand any lighting type with computer-grade power quality.
Through our robust double-conversion technology, the
TreStar 924 isolates and protects the connected load from the AC primary
supply, protecting it from damaging sags, swells, harmonics, noise,
voltage imbalances and interruptions (blackouts). In addition to meeting
life safety requirements, the TreStar 924 also can increase the life
expectancy of the protected lighting and reduce lon-term cost of ownership.
In the event of an AC power failure, the TreStar 924
will automatically transfer to battery power and continue to provide
power without any interruption for a full 90 minutes. When power returns
to normal, the TreStar 924 will automatically recharge the batteries
to be ready for the next power disturbance.
