Staco Introduces Emergency Lighting Inverter For 20 & 30kW Applications

Staco Energy Products Co. introduced the FirstLine® 924 three-phase Uninterruptible Power Supply (UPS) for 20 & 30kW central emergency lighting system. This true on-line, double-conversion central inverter provides computer grade power quality for virtually any lighting system.

In addition to providing a continuous power supply during blackouts, the FirstLine 924 isolates and protects the connected load from damaging sags, swells, harmonics, noise, and voltage imbalances in the primary ac supply. The company claims that isolating the connected load from irregularities in the primary ac supply can significantly increase the life expectancy of lighting systems and reduce the long-term cost of ownership. These features make the new FirstLine 924 suitable for public buildings, commercial and industrial facilities, high security areas, schools and universities, and more.

In the event of an ac power failure, the FirstLine 924 automatically transfers to battery power, providing a continuous power supply for 90-minutes, as required by NFPA 101. When power returns, the FirstLine 924 automatically recharges the batteries in preparation for the next power disturbance. Input voltage rating is 208Y/120 or 480Y/277, Delta connection with optional isolation transformer. Input voltage range is +/- 10% system start up, and +10%/-20% from nominal. Output voltage is regulated to +/-1% of nominal at full load. Total harmonic distortion is < 5% for non-linear loads, and < 2% for linear loads.

A front panel LCD display includes 2 x 24 character display which shows system status and alarms. The user-friendly control panel located on the front of the freestanding NEMA 1 enclosure allows remote monitoring through an RS232 connection.

"The new FirstLine 924 has been tailored to meet the demands of larger emergency lighting applications" said Staco Vice President Dave Kendall. "It meets life safety requirements and provides power conditioning and outage protection at an economical price. Customers will experience a lower cost of operation for both their central inverter and lighting systems. When coupled with the available options cabinet, the 924 is a well coordinated circuit distribution system."
