Product specs
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 LC520 Series is presented as a 380 V variable-frequency drive for controlling an AC motor in elevator and lift equipment. The listed electrical arrangement is three-phase 380 V input to three-phase 380 V output. It uses an AC-DC-AC conversion architecture with V/F control and PWM switching.
Listed operating features include a 0–500 Hz frequency range, fan cooling, an IP20 enclosure rating, Chinese and English language options, and RS485/Modbus communication. The stated working-temperature range is -10°C to 40°C.
The product information also identifies the unit as an AC/AC converter and lists motor, pump, compressor, and industrial-equipment control among its functions.
The source material contains conflicting model information: the product identity and category refer to the LC520 elevator VFD, while a later technical section describes the LC640 Series and provides LC640 model tables.
Buyers should therefore not apply the LC640 power, current, torque, voltage-tolerance, or protection data to an LC520 purchase without obtaining model-specific confirmation.
Before procurement, confirm the complete LC520 model code, rated input and output current, motor power, elevator-control mode, braking requirements, encoder or feedback provisions, control-terminal layout, and compatibility with the intended lift controller and motor.
Also verify installation clearances, cabinet protection, applicable safety requirements, supplied documentation, communication register map, customization scope, warranty terms, testing records, and delivery schedule for the exact ordered configuration.
