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
Product overview The LC520 is a low-voltage AC variable frequency drive presented for elevator and escalator motor control. It accepts 3-phase 380 V input with a stated tolerance of ±15% and provides an adjustable output from 0 V up to the rated input voltage.
Supported control methods include V/F control, sensorless vector control (SVC) and closed-loop vector control (FVC). The drive offers a 0–500 Hz frequency range and a carrier-frequency range of 2–16 k. Hz. Carrier frequency can be adjusted automatically according to load characteristics.
Linear and S-curve acceleration/deceleration are supported, with four acceleration/deceleration time sets and four S-curve setting sets. Multi-speed operation provides up to eight speed segments. Chinese and English interfaces are listed, along with RS485/Modbus communication and an IP20 protection class.
Listed 3AC 380 V ratings include 7.5 kW with 18 A rated output current, 11 kW with 27 A, 15 kW with 33 A and 18.5 kW with 39 A. The general specification identifies a broader 7.5–22 kW range, so buyers should confirm the exact available rating and current specification for the required model before ordering.
Procurement questions to confirm Ask for the precise LC520 model code, motor-rating match and current rating for the selected unit. Confirm whether the application requires encoder feedback for closed-loop vector control and whether the required encoder interface or accessories are included.
Buyers should also verify braking requirements, overload characteristics, duty cycle, enclosure needs, ambient operating limits, installation clearances, EMC provisions and applicable elevator or escalator safety requirements, since these details are not specified in the supplied product data.
Confirm the terminal arrangement, communication register documentation, included accessories and any requested logo or label customization before purchase.
