Introduction
The Flatpack Product Range
Eltek Energy's Flatpack product range utilizes the Flatpack rectifier and the MCU controller as
building blocks for implementing effective DC power systems, suitable for a wide range of
applications and power ratings.
MPSU
Modular Power Supply Unit
MPSU systems consist of the power system, which includes rectifiers and controller(s), and the
distribution unit (1U or 4U high). MPSU systems are sold primarily for mounting in existing
cabinets.
In PRS systems, the cabinet contains the power system and the distribution unit. In addition, the
cabinet may also enclose battery banks, additional distribution and other dedicated equipment.
