Import Ac Inverter — Buy in Bulk from Supplier in China

The AC inverter offered by China EM Technology Ltd. is a low-voltage variable-frequency drive in the 0.75 kW to 355 kW power range, built around the ABB Standard Drive ACS550 series architecture. It accepts standard three-phase industrial input and converts fixed-frequency supply into variable-frequency output for precise motor speed control across fan, pump, and conveyor loads. The unit carries ISO and CE marking for compliance with European safety and electromagnetic-compatibility directives, though buyers should request the specific certificate numbers and test reports before finalising an order. Output voltage tracks input voltage with a PWM waveform, and the drive is designed for direct wall or cabinet mounting in standard industrial environments.

The power module uses IGBT switching technology with built-in DC bus capacitance and braking chopper capability as standard across most frame sizes. Control options include basic keypad, panel-mount potentiometer, or remote PLC interfacing via analogue and digital I/O. Protection features cover thermal overload, short-circuit, earth-fault, and overvoltage conditions. The enclosure rating varies by frame size, with IP20 as standard for cabinet installation and optional IP54 kits for harsher conditions. Cooling is forced-air through internal heatsinks with automatic fan-speed control to reduce acoustic noise at partial load. Typical ambient operating range is -10°C to +40°C without derating, with linear derating to 50°C.

This drive suits manufacturing lines, HVAC fan and pump stations, water-treatment blowers, and materials-handling conveyors where energy recovery from variable load profiles justifies the capital outlay. Buyers range from OEMs integrating the drive into packaged equipment to facility engineers retrofitting fixed-speed motor installations. China EM Technology Ltd. lists flexible MOQ terms, though exact quantities and price bands are not stated in the source material and must be confirmed directly. The supplier is located in Shenzhen's Bao'an industrial district, a hub for electronics manufacturing and export logistics.

China EM Technology Ltd. is registered at No. 80, Baomin 2 Road, Xixiang, Bao'an District, Shenzhen, Guangdong Province, postal code 518101. The supplier is classified under the imported tier and holds a harbor trust designation. The response rate is recorded at 0.00 percent with an average response time of zero hours, which indicates that no response data is available rather than zero willingness to respond. Buyers should therefore initiate contact through multiple channels and allow adequate time for reply, or consider engaging a local sourcing agent in Shenzhen to bridge communication.

The company's product focus is industrial automation equipment, specifically variable-frequency drives for motor control. No information is provided about factory size, year of establishment, annual revenue, number of employees, or named client references. The listing does not state whether China EM Technology Ltd. is an authorised ABB distributor, a licensed assembler, or an independent brand using compatible architecture. Buyers should verify the exact supplier relationship to ABB, inspect quality-management certificates, and request reference installations before committing to volume orders.
