Eltek power systems are based on high efficiency modules and advanced controllers.

Eltek expertise lies in power conversion, i.e. the process of converting one type of current, i.e. AC, to another, DC, and in the process adjusting the voltage, making it suitable for specific delicate electronic equipment. This core functionality is combined with battery backup, distribution and advanced monitoring and control in complete power systems for industrial applications where the efficiency and reliability of power supply is business critical.


High efficiency power systems that reduce the cost and environmental footprint of energy usage, and that reduce the cost of ownership of power systems

Flatpack2 SHE rectifier

® Eltek

With an efficiency of 97.8% the Super HE is a premium rectifier particularly suitable for markets and applications where the energy is costly. In grid connected applications the payback time is down to 2 years compared to standard HE rectifiers, and in hybrid applications even faster.


Available voltages – 48, 60 VDC
Power – 2000, 3000 W modules


bidirectional converter

The Rectiverter is a 3-port device capable of charging the 48V battery and simultaneously provide power for AC and DC loads. During mains outage the Rectiverter feeds AC loads using energy stored in the battery.

Available AC Voltage – 230 VAC

Power combined for AC and DC  – 2000 W

® Eltek

Flatpack2 DC/DC HE/SHE converters

® Eltek

The Flatpack2 DC/DC converters add flexibility to the Flatpack2 power systems. Secondary 24V, 48V or 400 VDC outputs can be provided from the main voltage battery.

Available voltages – 380/48, 18-75/24, 18-75/48, 42-75/380 VDC
Power – 1350, 3000 W

Flatpack S DC/DC (HV) converter

The Flatpack S 48/750 HE UI module is designed to power standard 48V telecom equipment from a higher voltage power line.


Available voltage – 200-400/48 VDC

Power – 750 W module
