KONE V3F25 V3F18 Inverter A2 Board KM725800G01 KM725803H01

KONE KM725800G01 with PCB reference KM725803H01 is an inverter A2 board designed for compatible KONE V3F25 and V3F18 drive systems.

The board is installed inside the inverter assembly and forms part of the drive control system. It is commonly identified by the spare part number KM725800G01 together with the PCB marking KM725803H01. Before replacement, both numbers should be checked to ensure the correct board revision is selected.

Confirm the Original A2 Board

Although boards may look similar, different revisions can have different hardware layouts or drive configurations. Selection should always be based on the original board information rather than appearance alone.

Before requesting a quotation, please provide:

• complete KM725800G01 part number

• KM725803H01 PCB marking

• front and rear PCB photos

• inverter nameplate

• connector layout

• installation position

• drive model information

• fault code or maintenance report

• quantity required

Typical replacement requests include damaged PCB components, inverter communication faults, unstable motor control, burnt electronic parts, connector damage, or failures identified during drive maintenance.

If replacing the board does not solve the problem, technicians should also inspect the inverter power supply, encoder connections, motor wiring, brake circuit, cooling system, communication cables, and related drive modules before replacing additional components.

Installation and commissioning should be completed by qualified elevator technicians. After replacement, inverter parameters, motor operation, levelling accuracy, and safety functions should be verified before returning the elevator to service.
