Since 1991 DONG-IN ENSIS has designed and built control panels for industrial and marine sites. We build automation panels, PLC control panels and drive panels in our Yangsan Plants 1 and 2 and Gijang Plant, and carry out factory testing and site commissioning ourselves.
We follow your specification or designated brands. We have a design and build system for CE and UL standards.

A selection from 750+ projects. See the Applications page and the company profile for more.
Panel design, building and wiring, PLC programming, factory testing and site commissioning are handled by one company.
We test appearance and nameplate, enclosure and IP rating, clearance and creepage, mechanical operation, protective device settings, insulation resistance, dielectric withstand, protective earth, power and phase sequence, I/O and communication, interlocks and emergency stop, drives and PLC, alarms and protection, check every I/O point separately and ship with a test report.
Hybrid propulsion for green ships, LNG fuel gas supply (FGSS), liquid hydrogen refueling stations and production plant control systems in Korea and abroad.
Automation and PLC panels, drive and motor control panels, control consoles and system panels for marine and plant use, and the Intelligent Control Panel that also collects equipment data.
In our own Yangsan Plants 1 and 2 (completed 2023) in Gyeongsangnam-do and our Gijang Plant in Busan. The head office and R&D center are in Busanjin-gu, Busan.
The factory acceptance test (FAT) covers 13 items including appearance and nameplate, enclosure and IP rating, clearance and creepage, mechanical operation, protective device settings, insulation resistance, dielectric withstand, protective earth, power and phase sequence, I/O and communication, interlocks and emergency stop, drives and PLC, alarms and protection, and every I/O point is checked separately. Results are recorded in a test report, and customers can witness the test.
Yes. We review the existing panel and operating method on site, design and build the replacement, and schedule the changeover around your production plan. You can also start collecting equipment data with the Intelligent Control Panel at the same time.
Yes. Panel building, PLC and drive programming, factory testing and site commissioning are done by one company. Panel and program are tested together before shipment, which shortens commissioning on site.
We are an official Schneider Electric SI partner and have used SIEMENS, ABB, Fuji Electric, Phoenix Contact, Danfoss, Eaton and others. We follow your specification or designated brands.
It depends on the number of panels, ratings and specification. In our standard Intelligent Control Panel schedule, panel building takes about 5 weeks. We quote with a proposed configuration after a site review.
Tell us about your equipment and the panels you need, and an engineer will review it and get back to you. Please mention any drawings or specifications.
