3-phase UPS

The FirstLine 924 3-phase UPS central emergency lighting system is designed for 8kW to 16kW applications. In addition to providing a continuous 90-min minimum power supply, the UPS protects the connected load from sags, swells, harmonics, noise, and voltage imbalances in the primary AC supply. Input voltage rating is 208VAC or 480VAC with ±20% range for an input range of 166VAC to 250VAC and 384VAC to 576VAC, respectively, at 60Hz. Output voltage is regulated to ±1% of nominal at full load, and THD is less than or equal to 5% for nonlinear loads and less than or equal to 3% for linear loads. A front panel display includes 2 × 24 character display that shows system status and alarms.
