CRITICAL AREA LIGHTING & EQUIPMENT
|

1 |
An input high isolation
ferroresonant transformer provides power to a solid state rectifier, which
in turn, creates a regulated DC supply. This supply provides the power
requirements for the continuously running inverter. |
|
2 |
An input high isolation ferroresonant
transformer provides power to a solid state rectifier/charger, which in
turn, creates a regulated DC supply. This supply charges the battery |
|
3
|
A sealed maintenance free
battery is provided to maintain power to the inverter during a mains
failure. The battery is fitted with a suitably rated fuse to provide
overload and short circuit protection. |
|
4
|
A ferroresonant
transistorized static inverter transforms the DC voltage coming from either
the rectifier or the battery into regulated AC voltage to supply the
critical load. |
|
5
|
An electro/mechanical
automatic bypass switch connects the load normally to the inverter. In the
case of inverter failure or voluntary shutdown, the load is connected to the
utility. |

High Efficiency
Uninterruptable Power Supply
|
| |
Ferroresonant technology
reduces circuit complexity which in turn, doubles the factory warranty. The
inverter utilizes internal transistor redundancy which will allow up to 20%
of the power switching transistors to fail and still provide full load
output power. This combination achieves a reliability record envied within
the industry. Units are floor-mounted, force cooled UPS systems, with front
access for servicing. Cabinets contain air filters and knockouts for
interwiring with BX, Romex, or Conduit. The internal module consists of a
battery charger, AC-DC converter, DC-AC inverter, and batteries. Above
1.5kVA, a separate battery cabinet is supplied. |
