Scientific Research Building

The building covers an area of 33,333 square meters and is divided into five main areas: the Scientific and Research Center, No. 1 Workshop, No. 2 Workshop, Guest Building, and Security Room.

Overhead corridor

The first floor of No. 1 Workshop has three SMT production lines, and the second floor is where we assemble frequency inverters.!


Visitor Corridor

While walking along the corridor, visitors can observe our advanced production equipment acquired from the US, Germany, Singapore, Japan, and Taiwan. In the product exhibit, visitors can see our elevator control cabinet, general use AC drive, elevator inverters (including the elevator door inverter and elevator integrated drive and controller), and AC servo drives.        



Production Workshop

Our frequency inverter assembly lines select and deliver materials automatically. Each line assembles different models of 0.4KW-55KW elevator inverters, servo drives, and vector inverters. Each assembly line allows us to produce 80 units of AC drives every day. All of our assembly lines are equipped with high performance testing equipment and testing software to ensure the reliable performance of our elevator inverters.


Unloading Area

The unloading area has a large canopy so we can unload products in all weather conditions. An overhead corridor connects the No.1 and No. 2 workshops, wide enough for our forklift truck to transport goods safely.

Research and Development Center

The R&D center studies low voltage products, high voltage products, and servo systems.



Testing Area

The testing area tests our elevator door inverters, high voltage inverters, frequency inverters, and servo motors, and tests for thermal impact, abrasion-resistance, and load capabilities.

Stereoscopic Warehouse

The fully automatic stereoscopic warehouse is designed and constructed by OKAMURA Corporation, a Japanese business. It is computer controlled so operators can select products through the computer control system for efficiency. Two stackers accurately pick up or place goods on the conveyer belt smoothly.


Conference Hall

Our conference hall in the Scientific Research Building hosts 350 people for annual meetings and product release conferences.

Guest Building

This buildings hosts industry experts who visit us, provide technical support, or administrative guidance. We have 5 units of fully-furnished guest rooms, one restaurant, a bar, and two meeting rooms.
