Import Frequency Converter — Buy in Bulk from Supplier in China

The Shenzhen Powtech Co., Ltd. frequency converter uses a DSP-based control unit to deliver high-speed performance with SVC, VC, V/F, and torque control modes. It achieves sensorless vector control down to 0.25Hz and includes automatic motor parameter identification and slip compensation. The unit features a built-in simple PLC function capable of 16 speed segments and 4 acceleration profiles, with a hot-pluggable keyboard that stores and copies up to four parameter sets.

The device employs dual analog inputs with customizable control logic and supports standard RS485 and Modbus communication protocols for remote operation. Its PCBs are fully coated for environmental resilience, and the thermal management system includes a unique duct design and thermostat-controlled heat agencies to maintain stable operation under continuous load. EMC-compliant design minimizes electromagnetic interference, making it suitable for sensitive industrial environments.

This converter is commonly used in metallurgy, chemical processing, water treatment, textile machinery, and conveyor systems where precise speed control is critical. Buyers in manufacturing, mining, and utilities source it for applications like compressors, grinders, centrifuges, and hoists. Packaging is standard industrial carton with foam cushioning. Trade terms are FOB Shenzhen, with lead times typically 15 to 25 days after order confirmation. Minimum order quantities are not stated and must be confirmed directly with the supplier.
