Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Motors And Drives. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The LCGK LC640 is a compact, fan-cooled variable frequency drive designed for AC motors, water pumps, compressors, and industrial equipment. Its stated water-pump capability includes constant-pressure water supply control. The drive uses an AC-DC-AC topology with PWM control and supports V/F operation.
A built-in PID controller and standard RS485 communication are provided;Modbus is listed among the communication capabilities. Two electrical classes are specified. The 2T series accepts 220V single-phase input at ±15% and provides 220V three-phase output, with available motor power from 0.4 to 4 kW.
The 4T series accepts 380V three-phase input at ±15% and provides 380V three-phase output, covering 0.75 to 15 kW. Listed LC640 models have rated output currents from 2.1 to 32 A for the 380V range, while the stated 220V models include 0.75, 1.5, and 2.2 kW versions rated at 4, 7, and 9.6 A respectively.
Published operating details include a 0–500 Hz frequency range, 97%–99% efficiency, IP20 protection, and a working-temperature range of -10°C to 40°C. The interface supports Chinese and English.
Listed protective functions include overcurrent, overvoltage, undervoltage, module fault, electronic thermal relay, overheating, short circuit, and internal memory fault protection. OEM/ODM options are stated for items such as logos, labels, and molds.
Procurement questions to confirm: Buyers should verify the exact LC640 model, input phase and voltage, motor rated power and current, required output frequency, control method, and pump operating profile before ordering. Confirm enclosure suitability because the stated protection class is IP20.
Also confirm the required communication protocol, terminal and wiring arrangement, overload requirements, environmental conditions, accessories, OEM/ODM scope, and whether the selected model supports every function needed by the installation.
