1.Aluminum alloy CNC machining, high precision.

The cabient is made of 500 x 500 die-cast aluminum frame.With CNC machining process and
better splicing precision,EI series can achieve seamless splicing.
2.Climbing handle for fast maintenance in site.

3.Ribbonless design. Individual disassembly and easy maintenance.

4.Magnet Module front and back service.

5.High EMC design, low radiation, EMC class A.

6.Metal conductive heat dissipation, fanless silent operation.
7.Flexional design for flat and curve shape.

8.Power box back cover fast disassembly design without tool.
With modular design, the control box can be installed separately and disassembly,  more convenient for maintenance
9. Fast connection lock design.
