Accumulator block in explosion-proof enclosure BAVO
Consumed power 28 W maximum 7 variants of climatic version Operation tie at least 1.5 h
The block in explosion-proof enclosure is intended for use within explosion hazard areas with the possibility to connect to lighting fixtures, in which accumulator has not been previously provided ensuring their operation while powering off.
External explosion-proof accumulator block can be connected to lighting fixtures, in which accumulator has not been previously provided ensuring their operation while powering off.
External explosion-proof accumulator is currently intended for the following lighting fixture configuration: VELAN31-SD.L.10, VELAN31-SD.L.20, VELAN35, VELAN37.
In future, this list will be expanded.
Accumulator block BAVO is delivered only complete with lightng fixtures.
Block BAVO consists of accumulator, accumulator charger block and network detector and switching device block, heater and terminal block installed in explosion-proof enclosure. The enclosure cover is screwed into the body by thread. The body has three taps with threaded holes for cable entries and can be marked on plane surface. Accumulator charger block ensures accumulator charging, protection from short circuit, deep discharge, recharging and restriction of maximum discharging current. Network detector and switching device block controls voltage upstream and downstream external circuit breaker. If upstream external circuit breaker there is voltage, and downstream circuit breaker there is no voltage, then this is perceived as standard de-energization and lighting fixture is switched off. If voltage disappears both upstream external circuit breaker and downstream it, then this is perceived as emergency situation and lighting fixture is transferred for operation from accumulator. Heater switches on accumulator heating at low operating temperatures. Currently block BAVO is intended for the following lighting fixture configuration: VELAN31-SD.L10, VELAN31-SD.L20VELAN35-SD.L8, VELAN35-SD.L15VELAN37-SD.L15, VELAN37-SD.L20, VELAN37-SD.L25.
