We received a Mitsubishi FR-F740-06830-E1 driver, 315kW power, to diagnose a fault and quote repair.

As preliminary information, the client indicated that the protections tripped, so we decide not to carry out diagnostic tests with voltage. We proceed to the disassembly of the equipment and to review the equipment by components.

The input rectifier is checked, detecting that it was damaged; the output IGBTs bridge is checked, verifying that it was also crossed; the control plates are tested, verifying that they were also damaged.

Next, we proceed to replace all the damaged components and finally we pass the equipment to the test bench; the corresponding verification tests are carried out to confirm the correct operation of the equipment.

Our standard repair time is 2 weeks. This term may vary depending on the availability of spare parts or components or for any other justified cause beyond Generis Electronics. If you need urgent repair, we can also offer an exchange service. This option is available for a wide variety of equipment. You only have to send us your damaged equipment and we will send you a refurbished item in 24-48 hours.
