924 Emergency Lighting UPS

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.
