Import Frequency Inverter — Buy in Bulk from Supplier in China

The frequency inverter offered by Cnc Makers Ltd. is designed for variable‑speed drive applications and incorporates an internal PID controller with sixteen speed‑step settings. It accepts an input voltage of 380 V or 220 V with a tolerance of ±15 % and operates on an input frequency between 47 Hz and 63 Hz. Output frequency is adjustable from 0 Hz up to 650 Hz, while the output voltage can be set from zero to the rated input voltage. Control can be performed through a PC or PLC via an RS485 interface that supports Modbus RTU and ASCII protocols.

The unit provides six open‑collector digital inputs and a single digital output, together with two analog output channels for monitoring. Analog signals are available as a 0‑4 mA/0‑20 mA or 0‑10 V FM terminal and a 0‑10 V AM terminal, the latter limited to models of 7.5 kW and below. A programmable PWM channel ranges from 0 kHz to 50 kHz, allowing fine tuning of motor drive characteristics. The inverter’s construction follows standard industrial enclosure practices, delivering typical IP20 protection.

This inverter is suited for manufacturers of conveyor systems, packaging machinery and other equipment that require precise speed regulation. Buyers should confirm the available communication protocol settings, the exact power rating and any required certifications before placing an order. Trade terms are not disclosed in the listing, so request FOB or CIF conditions and payment options directly from Cnc Makers Ltd. A clear inspection plan and test report should be arranged to verify functional performance.

Cnc Makers Ltd. is located at No.168 Xiadu Road, Haizhu District, Guangzhou, Guangdong, China. The supplier is listed as an imported tier with a harbour trust tier, indicating that it sources products for international buyers. Platform data shows a response rate of 0 % and an average response time of 0 hours, so prospective buyers should verify communication responsiveness early in the dialogue.

The company advertises frequency inverters equipped with PID control, multiple I/O options and RS485 communication. No additional corporate history, production capacity or client list is provided in the listing, therefore all claims are limited to the technical description supplied.
