Variable frequency drive
STEP has been focusing on the fields of power electronics and motor control for over two decades. It boasts a fully integrated value chain—from independent R&D platforms and design to manufacturing, sales, and inspection—as well as a fully automated intelligent assembly line for integrated drive and control systems. STEP's high- and low-voltage variable-frequency drive platform covers the entire power range, with an annual production capacity of 500,000 units.
Relying on a multi-brand strategy encompassing"STEP","iAStar"and"SIGRINER",STEP continues to lead the markets for smart water management, HVAC systems, and logistics & warehousing drive-control systems. It has earned deep trust in the field of electrical control systems for open-mill and closed-mill rubber tire machinery, and is also widely applied in industries such as elevators, lifting equipment, marine and offshore engineering, mining, and general energy-saving applications.
