Power supplies. (Market Place).
The BPS series of filtered and regulated DC battery-charging power
supplies from Securitron Magnalock Corporation of Sparks, Nevada, are
rated Class II by Underwriters Laboratories. That classification means
that output wires do not require a conduit, thus saving installation
costs. The power supplies come in 12 models ranging from 1 to 15 amps at
12 volts and 1 to 10 amps at 24 volts. The units are furnished in
wall-mount hinged-steel enclosures with safety warning lamps on the
front. Sealed lead-acid battery packs can be added for automatic backup
power. Units with more than 1-amp capacity feature four or eight
separate circuits, each protected by automatic circuit breakers with
status indicators. A short circuit on one zone is automatically switched
off while other zones operate normally. Power supplies carry a two-year
warranty in addition to safes and technical support.
