Product Overview


Flatpack2 24V/1800W HE
The combination of innovative design, efficiency and reliability makes the Flatpack2 HE stand out.
Compared to older technologies with even poorer efficiency an investment in a Flatpack2 HE system is repaid in a few years by the reduced operating cost.

Reliable high efficiency rectifier for industrial applications
The Flatpack2 modular concept has a lot of benefits compared to traditional solutions in the industry. It has high efficiency; less power consumption and heat dissipation. The overall Size and footprint of cabinet is 50% of Thyristor Controlled Size. Modular Hot Plug-in Construction allows redundancy, n+1, n+2 configurations.
It's easy to do repairing with MTTR< 5 minutes.Very high MTBF > 350000 hours, wide input AC Voltage and frequency
range.Possibility to build combined systems with rectifiers, DC/DC converters and inverters controlled by one controller.

Key Features :
Digital controllers
Heat management
OR-ing protection on output unique connection
Global approvals
