Exeltech BBS Cat. No. ELX-BBS Weight 15 lbs

The Exeltech BBS is an integrated inverter/charger system with transfer switch. Several key features allow the Exeltech BBS to stand out among other battery backup systems. It is designed to provide backup power for critical LED traffic light intersections. With 1,000 watts of true sinewave power available, the Exeltech BBS will drive most large LED systems. Its pure sinewave output is cleaner than utility power, making it ideal for all loads. Total distortion is typically less than 1.5%. Manufactured in the USA to the highest standards possible, Exeltech's BBS system is the best choice for critical load protection. Overall system features: * Inverter/charger designed for seamless operation together * Certified temperature range -37C to 74C * 3 alarm relays for external monitoring On battery; energized when running on battery Low battery; energized when 40% of battery capacity remains On time; energized after two hours on battery * Low battery shutdown protection at 1.75 Volts per cell * LED display allowing several counters and status monitoring BBS status: BBS mode, charge state 1, 2, or 3 Event counter Event timer Accumulated Event time Battery Voltage * Maintenance bypass switch * Testing and certifications Manufactured in accordance with ISO 9000/TL 9000 quality systems Computerized calibration and testing of each system CALTRANS compliant TX DOT compliant ANSI-C62.41 Level B2 FCC compliant to Part 15 Class A Totally integrated system with a 20 year MTBF BBS charger features: * Power factor corrected * Standard 3 state charger; bulk, absorption, & float * Battery temperature sensor for temperature compensated charging * Charging in excess of 150 watts.
