Baldwin Boxall BVSMPLT datasheet
voice alarm
POWER SUPPLIES
Both units in the range employ ‘switch mode’ techniques to improve efficiency and reduce
unwanted heat dissipation and weight. There are currently two models in the range:
BVSMP
•
BVSMPLT
Features:
•
The BVSMP has two individually protected outputs at
24V; the BVSMPLT has one.
•
Each BVSMP will drive either two BV220, two BV120D,
two BV050Q or one BV440M.
•
Each BVSMPLT will drive one BV220, one BV120D or one
BV050Q.
•
Provide independent power converters with current and
over-voltage protection circuits.
•
Continual monitoring of the charger and all DC outputs
ensures reliability.
•
Standby batteries are continually ‘float charged’ by the
unit. Ensuring that, in the event of mains failure, power is
maintained.
•
Built-in deep battery discharge cut off, preventing total
discharge that can destroy the standby batteries in the
event of AC power failure for long periods.
•
A protected output is provided to power a mixer or
auxiliary circuits.
•
In the event of a fault condition an internal relay releases,
providing a changeover contact. A fault will be indicated
on the EVAS router.
•
The constant voltage charger is set for the recommended
float charge. Should the battery fall below this level the
BVSMP will charge at a constant rate of three Amps,
progressively reducing once the battery has achieved its
nominal float level.
•
Outputs, together with a volt-free (fault changeover)
contact, are provided by a nine-way crimp connector plug
and socket.
•
Several chargers may be paralleled when used for larger
systems. (Paralleled BVSMPs must be synchronised).
Front panel indicators:
•
AC supply healthy.
•
Fuse failure.
•
Charger failure.
•
Battery voltage high.
•
Battery voltage low.
•
OK.
(lamp test switch for the above indicators).
BATTERIES:
•
We recommend (and supply) high-quality lead
acid batteries. They are sealed, valve regulated and
maintenance free. As standard our batteries are available
rated at 15, 40, 60, 75, 90, 110 and 125 Ampere hours.
Larger standby systems can be provided and will be
designed and calculated by our engineers. It is important
that all voice alarm batteries comply with BS5839 or
EN60849. The batteries activate when the mains has
failed under emergency conditions.
