Mitsubishi RM725 is a drive power circuit board assembly with a screw terminal strip, transformer, capacitors, insulated wire links and signal connectors. The photographed board carries Mitsubishi Electric Corporation identification and is marked Made in Japan.

Additional identification on this assembly includes RM725B and BN638A509G52, with an A marking beside the PCB number. Use the complete identifiers and original drive nameplate when requesting a replacement; the RM725 reference alone does not establish compatibility.

RM725 Product Information

Power Connections and Populated Board Layout

The supplied photographs show the terminal strip along one edge, bolted connection points, shaped insulated wire links and a central transformer. Connector markings include TE1, CON1 and CON2. Compare the terminal positions, connector keying, board outline and mounting points with the original assembly. Visible labels do not establish electrical ratings or pin assignments.

RM725B and BN638A509G52 Identification

Keep RM725 as the primary enquiry reference and provide clear photographs of RM725B, BN638A509G52 and all revision labels. Match the complete PCB number, including G52. Do not assume that a board with a different ending is interchangeable without checking the original drive and assembly configuration.

Supply Scope and Replacement Checks

Confirm whether the quotation includes the transformer, terminal strip, capacitors, wire links and connectors shown. Before installation, have a qualified technician check the original fault and mating connections. The PCB carries a high-voltage caution label; isolate the equipment, follow its discharge procedure and verify absence of voltage before handling the board.
