Eltek Valere announced the Industrial Building Block (IBB) high-efficiency (HE) DC power systems designed for high-reliability 24-VDC to 220-VDC industrial applications.

The IBB systems replace industrial battery chargers with a modular system that brings higher reliability and enhanced monitoring and control in a form factor that is compact, lighter and easier to install. The core of the IBB is the Eltek Valere Flatpack2 HE wide output range (WOR) switch mode rectifier. The rectifier features 94% power-conversion efficiency for greener operation and lower power costs, compared to the 85% to 90% efficiency offered by typical battery chargers.

The Flatpack2 HE WOR achieves a mean time between failure (MTBF) of more than 300,000 hours. Additionally, the IBB has N+1 redundancy through the use of multiple, plug-in rectifier modules that operate in parallel and share the load. The failure of any single rectifier has no effect on the overall load and mean-time-to repair can be less than five minutes.

The rectifiers also can be configured as DC-DC power converters to adapt 85-V to 300-V DC power to 48-V or 24-V DC power in order to power communications equipment without a separate power infrastructure.

The Smartpack2 controller is a key component of the system and delivers a wide range of remote battery monitoring and testing functionality that can simplify maintenance and ensure maximum battery life. The controller also has the processing capability to support existing interfaces to SCADA systems and the ability to be upgraded as new protocols emerge.

The IBB product line includes the IBB 250 and the IBB 500, systems that provide capacities up to 250 A or 500 A respectively. Both IBB models can be configured in cabinets that also can accommodate batteries, inverters, converters or load breakers into a complete system managed by the controller.
