RICHARDSON, USA: Eltek, the world leader in high efficiency power systems, today announced it has ramped up its -48VDC battery distribution fuse bay (BDFB)/battery distribution circuit breaker bay (BDCBB) with an industry-leading 800 amps of power per bus and a total current capacity of 4800A. This ensures an uninterrupted power supply for large telecom network central offices and wireless mobile telephone switching offices (MTSOs).
Telecommunications equipment requires power redundancy from the battery plant, and the BDFB/BDCBB provides a variety of load busses and fuse options to meet redundancy requirements. The unit can be configured as a single bus bay or equipped with up to six separate load busses. Both fuses and circuit breakers are accommodated.
“Demand for mobile broadband and cloud computing continues to grow and networks must have reliable power with battery backup to ensure continuous service,” said David Leal, Eltek’s VP of North American sales. “The new version of our BDFB offers the industry’s highest power as well as advanced remote management and control.”
Additional flexibility has been added with flexible support for either fuses and/or circuit breaker distribution that utilizes TPS/TLS-style fuses up to 125 amps and/or plug-in bullet-style breakers up to 250 amps.
The BDFB/BDCBB is equipped with Eltek’s industry-leading Smartpack2 controller, which displays system load voltage and current on each bus and provides extensive programming and monitoring capabilities that enable custom alarm threshold values, alarm grouping and more via both remote and local access.
An optional alarm battery supply (ABS) is included, which provides continued alarm and controller access in the event of power loss. The ABS features redundant alarming, so power is continuously supplied to the alarm circuits until the last bus no longer has power available. An audible alarm is provided with a user-configurable on/off feature.
The BDFB/BDCBB is easy to install and is field upgradable. The entire footprint is 15 inches deep by 7 feet tall, with optional 2 and 4-foot extensions. The cabinet can be configured with either an internal or external ground return bus assembly; optional external ground bars are also available. The BDFB is designed for either top- or bottom-feed cabling.
The BDFB/BDCBB comes with two, four or six input feeds, each equipped with shunts upgraded to 1,000 amps. It is certified to NEBS, UL and CSA requirements.
