Люминесцентные аварийные балласты Bodine B70A

Приложение
The B70A emergency ballast works in conjunction with an AC ballast to convert new or existing fluorescent fixtures into emergency lighting. The emergency ballast consists of a high-temperature
nickel-cadmium battery, charger and electronic circuitry in one compact red case. The B70A can be used with most 32 – 215 W (4’ – 8’) T8, T12 fluorescent lamps without integral starters, including U-shaped. It is also compatible with most one, two, three and four-lamp electronic, standard, energy-saving and dimming AC ballasts. If used in an emergency-only fixture, no AC ballast is necessary. The B70A is suitable for indoor and damp locations and for sealed & gasketed fixtures, including fixtures rated for wet locations. It is not suitable for air handling heated air outlets or wet or hazardous locations. For information about specific lamp and ballast compatibility, please contact Technical Support.
Операция
When AC power fails, the B70A immediately switches to the emergency mode, operating one lamp at a reduced lumen output for a minimum of 90 minutes. Two-hour duration may be selected with one 32 W T8 or one 34 – 40 W T12 fluorescent lamp. 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 three seconds to prevent false tripping of the AC ballast end-of-lamp-life shutdown circuits.
