BODINE LP550 FLUORESCENT EMERGENCY BALLAST 120/277 Illumination Time - 90 Minutes Initial Light Output - 39 - 700 Lumens Dual Input Voltage - 120/277 VAC, 60 Hz AC Input Power Rating - 2.6 Watts Battery - High-Temperature,Maintenance-FreeNickel-Cadmium Battery 7- to 10-Year Life Expectancy Battery Charging Current - 180 mA Charging Indicator Light - LED Temperature Rating (Ambient) - 0°C to +55°C (32°F to 131°F) Dimensions - 18.5†x 1.18†x 1.18†(470 mm x 30 mm x 30 mm) Mounting Center 18.1†(460 mm) lighting commonly used in office, hospitality, health care, retail and educational facilities. When AC power fails, the LP550 immediately switches to the emergency mode, operating one lamp at a reduced lumen output for a minimum of 90 minutes. When AC power is restored, the emergency ballast automatically returns to the charging mode and, using a patented circuit, delays AC ballast operation for approximately 3 seconds to prevent false tripping of the AC ballast end-of-lamp-life shutdown circuits. The LP550 does not affect normal fixture operation and may be used with either a switched or unswitched fixture. If a switched fixture is used, an unswitched hot must be connected to the emergency ballast. The emergency ballast must be fed from the same branch circuit as the AC ballast. The LP550 may be installed inside or on top of the fixture. Installation is not recommended with fixtures where the ambient temperature may fall below 0°C. The LP550 has been tested by Underwriters Laboratories in accordance with the standards set forth in UL 924, “Emergency Lighting and Power Equipment,†and is UL Listed for factory or field installation. Emergency illumination time exceeds the National Electrical Code (NEC), Life Safety Code (NFPA-LSC) and UL 90-minute requirements. (We do not proofread any ads submitted by members) |
