OEM panel builder
Engineering control systems and building panels is core business for Eltra. Applying local standards and specific user requirements or special conditions regarding to climate and safety devices is standard procedure for Eltra employees. That is why every panel gets full attention and detailed engineering.
Wiring diagrams and detailed schematics are designed with eplan® electric P8. Both graphically and object oriented engineering (2D) is possible.
Engineering and building control panels is performed by skilled employees with high quality standards. Each panel is functionally tested by connecting I/O and safety circuits to live test boards. Frequency and servo drives will be tested using real motor loads.
