The systems are supported by Eltek Valere's Smartpack Controller for monitoring and control, and can be integrated with the company's solar inverter products in hybrid solar/grid applications. The complete HE product line includes the Flatpack2, Compact and Integrated DC power systems, along with both 24 V and 48 V rectifiers ranging from 1.8 kW to 3 kW, offering carriers the ability to architect a complete HE system of up to 6000 A. The rectifier offers 62.5 A of current per module, giving it a power density of 33 W/in 2, a global operating range of up to 300 VAC and UL-rated AC range extended to cover an input voltage of up to 277 VAC. The new Flatpack2 HE 48/3000 rectifier is the highest wattage rectifier in Eltek Valere's HE family and brings these green solutions to the central, wireless macrocell base stations and the network core.
The announcement marks the last of its flagship Flatpack2 rectifier products to be available in an HE version, a process started in 2008 when the company pioneered green DC power systems.
Eltek Valere (Drammen, Norway) has unveiled the Flatpack2 HE 48/3000, a 48V, 3 kW rectifier that operates at 96 percent efficiency.
