Mitsubishi GPS-3 drive and cabinet boards:
Potensi supplies the Mitsubishi GPS-3 high-voltage power board KCN-755A, the Mitsubishi drive power board P203724B000G01 and other Mitsubishi elevator spare parts. The models above are only a part of what we can supply. We stock and source a much wider range of related and alternative models. If your model number is not listed here, please send us the model number or a photo of the original part, and we will confirm availability and the correct match for you.
Q1: What does the KCN-755A do?
A: It is the high-voltage power board of the GPS-3 drive, mounted in the drive section of the control cabinet. It works on the high-voltage side of the inverter and absorbs the overvoltage produced by switching. Some suppliers describe it as an overvoltage absorption board or a module board rather than as a complete power board.
Q2: Which part number should I quote?
A: The board is supplied under P203724B000G01. It is also written KCN-755 or KCN755A in some catalogues, and KCN-755A is the marking most often printed on the board itself. Please send a photo of the label, because the part number and the model marking appear together on this board.
Q3: Is the KCN-756A the same board?
A: The two models are often listed together under the same part number P203724B000G01. They belong to one family but are not confirmed as interchangeable, and the rating may differ. Please tell us the drive rating and send the old board photo before you choose between them.
Q4: Which Mitsubishi systems use this board?
A: It is used on GPS-3 (GPS-III) drives, including HOPE-2 lifts. The same cabinet generation also uses the KCN-710A power supply board and the KCR series drive boards. Please send the drive nameplate and the cabinet photo, and we will confirm the correct version.
Q5: What should be checked before replacing this board?
A: This is a high-voltage board, so the DC bus capacitors must be discharged before the board is removed. Check the DC bus capacitors, the IGBT module and the incoming supply as well, because a fault outside the board can damage a new one. Loose terminals and burnt connectors should be repaired before the replacement board is fitted.
Q6: How can I confirm this board matches my drive?
A: Send us the label photo, the connector positions and the drive nameplate. The model marking, the part number and the plug layout together identify the version. If the label is damaged, the drive model and the cabinet type are usually enough for us to confirm it.
