 2000 50A -48V 364A-3 SR Series Rectifier 

2 - 4  Product Description 

Issue 6  January 1997

SR Series 
Rectifier 
Technology

The Lucent Technologies family of SR series rectifiers 
represents a significant advancement in space utilization, ease of 
installation, and weight reduction over previously available 
products.

The Lineage

®

 2000 364A3 50-ampere, -48-volt SR series 

rectifier uses switchmode technology to convert commercial 
50/60 Hz ac input power into highly regulated and filtered, 
low-noise, -48-volt dc output power for telecommunications 
equipment loads. Since telecommunication systems typically 
obtain their primary power from potentially noisy commercial ac 
lines (and emergency alternators during commercial power 
failures) and since high-quality dc power is required in order for 
the equipment to function correctly, the 364A3 rectifier is an 
excellent choice for a telecommunications power plant. The 
rectifier provides excellent output regulation over a wide range 
of load currents, input voltages, and input frequencies. 
Processing the power at higher frequencies allows for substantial 
reduction in the size and weight of the energy storage elements. 

Benefits

Improved Space Efficiency: A unique Lucent Technologies 
Bell Laboratories design, which incorporates 70 kHz switching 
frequency, has resulted in rectifiers which occupy approximately 
one-third of the space and weigh one-seventh as much as 
comparable ferroresonant rectifiers. The 364A3 rectifier plugs 
into a shelf assembly that can house three rectifiers. In addition, 
several rectifiers can be configured in parallel arrangements to 
provide capacities up to 600 amperes in 48 inches of vertical 
space. 

Reduced Installation and Maintenance: Its unique plug-in 
design, front access capability, and light weight make the 364A3 
rectifier easy to install and simple to maintain.

Continuous Operation: 364A3 rectifiers can easily be added to 
Lineage

®

 2000 battery plants without interrupting power to the 

load.

Increased Cost Effectiveness: Space efficiency, ease of 
installation and maintenance, high reliability, and a near unity 
power factor result in lower operating costs. The 364A3 
rectifier’s modular design allows your plant to begin small and 
to grow as required.
