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.
AS720S Liquid-Cooled Series Inverter
Airborne installation, wide temperature range, flexible and reliable.
AS800 High-Voltage Frequency Converter
The AS800 high-voltage variable frequency drive meets the stringent IEEE 519-2014 requirements for current harmonic distortion; it features a standard protection rating of IP31, with an optional IP42 rating; and is suitable for use with asynchronous high-voltage motors, permanent-magnet synchronous high-voltage motors, and more.
AS-M210 Small High-Performance Inverter
Lightweight and compact design with consistent dimensions Achieves optimal product miniaturization in a rational and effective manner Combines light and heavy-load capabilities, enhancing product versatility All-aluminum base, 2g vibration resistance rating; fanless design for light loads up to 2.2kW
ET6/EP6/EH6/ES6/EM6 Intelligent Flexible Variable Frequency Drive
Automatically matches motor types; no derating required at ambient temperatures up to 50°C; built-in industry application macros; CE-certified.
The AS180N(-B) builds upon the previous model with iterative upgrades, featuring a smaller footprint and increased power density. This unit comes standard with an LED operator; the B model comes standard with an LCD operator, both of which support external operator connections. The design boasts a more industrial aesthetic. Leveraging GVC vector control technology, this product further enhances its reliability, environmental adaptability, and customizable and industry-specific design capabilities, making it well-suited to meet a wide range of drive requirements.
