Customer Service

TDK-Lambda provides a comprehensive after sales service to all our customers. Additionally, TDK-Lambda can provide service for products based in Germany, which have been supplied by the world-wide network of the TDK-Lambda Group of companies.

If the warranty is still valid then the cost of the repair is free to our customers, however TDK-Lambda are pleased to offer a service for non-warranty repairs, most of which are on a fixed price basis. Due to unknown external environmental factors, it is recommended that units 10 years from date of manufacture are replaced with new.

Note* this does not include units with a limited lifetime warranty:

For any queries please use the contact section of our website.

TDK-Lambda operates a Returns Material Authorisation (RMA) system for returning product. We cannot accept returned goods without an RMA number. Please register/log-in using the links, below, in order to submit your return details & obtain an RMA number. Upon returning the repaired power supply to you, we provide a report which details the repair action. The repair itself is guaranteed for 6 months, which ensures all product approvals are maintained.

Supplementary Repair Terms
To prevent delays and transport damage during the repair process, we kindly request that you comply with the following terms:

• The device must be accompanied by the applicable RMA number (packing note), preferably clearly marked on the accompanying shipping documents.
• The return shipment must be packaged in the original packaging or in packaging of equivalent protective quality.
• Packaging guidelines are available from your carrier or parcel service provider. It is the sender’s responsibility to ensure adequate packaging.
• Devices weighing more than 50 kg and/or sensitive equipment must be delivered upright on a pallet to avoid transport damage. We recommend that devices from approximately 30 kg upwards also be shipped securely on a pallet.
• We reserve the right to refuse acceptance of shipments that arrive with clearly inadequate packaging.
• Under no circumstances will freight collect (carriage unpaid) shipments be accepted by our incoming goods department.
• We assume no liability for accessories (e.g., wiring harnesses, add-on parts, etc.) sent with the device. All such items must be removed prior to return shipment. Original accessories that were included with the product at the time of delivery, are exempt from this requirement and should be included with the return.
• Additional services, including but not limited to the removal of attachments or disassembly of devices from housings or cabinets, are not covered under warranty and shall be subject to additional charges.
• Debit notes shall only be accepted if submitted no later than the date of receipt of the returned goods. Deductions may be processed subsequently; however, the period for such deduction shall not exceed two (2) weeks.
• In the absence of a response to our cost estimate, including two subsequent reminders, we reserve the right to return the device six (6) weeks after the date of the original quotation.
• In cases where no fault is found, the customer may be charged for inspection, shipping, and related administrative costs.
• In the event of a Beyond Economic Repair (BER) diagnosis outside the warranty period, we reserve the right to charge the customer for the proper disposal of the device or for return shipping costs.
