Product Description
Function
In most telecommunications applications, the output of the rectifier
system is electrically connected in parallel with the batteries. The
rectifiers provide both the power to the telephone equipment through the
plant distribution and the charging and float current to the batteries. In
the event of commercial power failure, the batteries supply the required
dc power to the telephone equipment. This transition needs no switching
because of the parallel connection of the rectifiers and batteries.
Benefits
The J85503C-3, 400-ampere, 60-Hertz rectifier offers you the following
benefits:
•
Eliminates internal switching transients typically associated with
older technologies.
•
Reduces noise and transients from the commercial ac source. As the
interface between commercial power and telephone equipment, the
ferroresonant rectifier significantly attenuates noise and lightning
surges from commercial lines.
•
Introduces far less noise into closely coupled telephone lines due to
lower harmonic components in the input current waveshape.
•
Provides highly efficient power conversion.
•
Ferroresonant technology and the rectifier's physical design
features combine to provide reliable service, easy maintenance, and
greater cost effectiveness.
•
All components in the rectifier meet Lucent Technologies' strict
specifications and reliability standards. The rectifier uses an
extremely efficient, free-convection cooling system that keeps
components operating at temperatures well below the
recommended maximum, resulting in high reliability.
