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.
AS620 High-Performance Variable Frequency Drive for Lifting Applications
Input voltage: (380–460) V (-15% to +10%), three-phase power supply, voltage unbalance < 3% Input frequency: 45–65 Hz Transient voltage dip: When the input voltage drops below AC 300 V during operation with a three-phase AC (380–460) V power supply, undervoltage protection will be activated after 15 ms.
AS600 Series Frequency Converters for Lifting Applications
The AS600 series frequency converters specially designed for lifting applications are developed by Shanghai Xinglinna STEP Motor Co., Ltd. for the industrial crane sector, including such cranes as quay-side container gantry cranes, container portal cranes, pedestal cranes, and bridge cranes.
AS450 High-Performance Vector Inverter
The AS450 series variable frequency drives are the latest VFDs designed by Shanghai Xinglinna STEP Motor Co., Ltd. specifically for the Chinese market. This product is suitable for induction asynchronous motors. It adopts today’s internationally leading sensorless vector control technology, closed-loop vector control, and torque control technology. Not only does it deliver control performance that is just as excellent as those of high-end international VFDs, but it also takes into account China’s unique application characteristics, further enhancing the product’s reliability, environmental adaptability, and customization and industry-specific design capabilities. As a result, it can better meet the demands of various heavy-duty drive applications.
