Eltek Valere Debuts -48Vdc Battery Distribution Fuse Bay
Eltek Valere debuted its new 48Vdc battery distribution fuse bay (BDFB). According to the company, this versatile, advanced-function distribution bay ensures a continuous power supply for large telecom networks and wireless mobile telephone switching offices (MTSOs).
The 48Vdc BDFB provides a variety of load busses and fuse options; it can be configured as a single bus bay or equipped with up to six separate load busses, depending upon the desired configuration. Both fuses and circuit breakers are accommodated. The BDFB has a capacity of 600A per bus at -48V, delivering a maximum total current capacity of 3600A.
"The growth in mobile broadband applications and cloud computing is driving the need for higher power in networks, and that results in more demand for battery backup for increased reliability," said David Leal, Eltek Valere’s Vice President of North American Sales. "Our new BDFB brings a new level of flexibility, remote management and control to these applications."
Monitoring and control of the BDFB is crucial for high reliability and availability, as well as for performing periodic maintenance operations. At the heart of the BDFB is Eltek Valere’s Smartpack2 controller, which offers remote and local access to system data; programmable settings and alarming; and monitoring. The color display panel shows load voltage and current on each bus. In addition to standard alarms, the Smartpack2 controller’s extensive programming capabilities allow for custom alarm threshold values, alarm grouping and more via both remote and local access.
An 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 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 comes with two, four or six input feeds, each equipped with 800A shunts. It is designed to meet or exceed NEBS, UL and CSA requirements.
