Frequently Asked Questions

This page contains answers to the questions most frequently asked by our customers:

What is your connection to Farnell / Advance Power?

We are all ex Farnell / Advance Power PSU design engineers with over 50 years combined experience. After the buy-out of Advance Power by American Power Conversion in 1999 and subsequent closure of the UK design and manufacturing division in 2002, we set out to create a fully independent company called Advance Product Services Ltd., with the sole intention of supporting and servicing the products manufactured by Farnell & Advance Power since 1952. We are a dedicated organisation that specialise in this area, no-one else has our level of expertise and understanding of Farnell / Advance products.

How do I send a power supply for repair (UK customers)?

To ensure that your power supply is repaired and returned as quickly as possible, please use the following procedure:

Read our Terms & Conditions relating to unit repairs.

Obtain a quotation from Advance Product Services Ltd. You can do this by filling in the online quotation request or by contacting us by email, phone or fax. Remember we offer a fixed repair charge for all Farnell / Advance Power items.

If the quotation is acceptable and you are a new customer, fill in and fax back our customer registration form. This will allow us to add your details to our system and (subject to approval) offer payment on 30 day credit terms.

We will then await the unit from yourselves which should be sent by traceable means along with any purchase orders and details of the fault (if known), to our standard business address. Alternatively, we can arrange for the unit to be collected from your premises using our courier.

Once the unit has been received, it will be evaluated, repaired and tested as soon as possible. If there are any problems which will delay the return of your unit we will contact you immediately. When complete, the unit will either be:

  1. Returned using our courier on next day delivery for customers with a credit account.

  2. Be held in our goods out department until payment has cleared for customers without a credit account. We will issue an invoice for the work carried out and release the unit upon clearance of payment.

Alternatively, you may collect the unit from our premises in person or arrange your own transport service.

All repairs are covered by a 12month warranty, and remember we do not charge a penny if we fail to repair a faulty unit.

Are you the original manufacturers of Farnell / Advance power supplies?

No, but in many cases we were the original designers of these products having been employed by Farnell / Advance for many years. Advance Product Services Ltd is a fully independent company dedicated to supporting and servicing the products manufactured by Farnell / Advance Power since 1952. We are an organisation that specialise in the repair and replacement of these items. No-one else has our level of expertise and understanding of Farnell / Advance power supplies.

Do you sell new power supplies?

The vast majority of Farnell / Advance power supplies are now obsolete, however we have a comprehensive database of power supplies from alternative manufacturers which in many cases make suitable replacements in terms of voltage, current and approximate physical size. We can supply these products on request and would be happy to discuss your requirements.

Where an exact fit, form and function replacement is required including signals and fixing points, we have developed our own range of new PSU's which can be fitted with complete transparency to the end user. These PSU's are custom designed to meet or exceed the original Farnell / Advance specification in all areas.

Please see Product Replacements for more details.

Do you charge a survey fee?

No. We adhere to a 'no fix, no fee' policy which means if we fail to repair a faulty unit then we do not make any charges for fault diagnosis or surveys. Should we receive a unit which is not faulty we reserve the right to charge a small fee to cover labour and testing costs.

What if my unit fails again after you have repaired it?

We pride ourselves on providing professional repairs by time-served Farnell / Advance Engineers. Our rate of returns over a 1 year period post-repair is less than 0.2%. Should your unit fail again within it's warranty period, simply send it back to us and we will investigate the failure. If it is as a result of any work we have carried out, directly or indirectly then we will return the unit to a working state free of charge. If the failure is a result of customer or environmental abuse (physically dropped, lightning strike etc) we reserve the right to make a further charge to return the unit to full working order.

What warranty do you give on your repairs?

We are so confident in the quality and effectiveness of our repairs we offer a full 12 month warranty from date of repair. Typically, other repair houses offer only 3 month warranty periods.

What happens if you cannot repair a unit?

In rare cases, a unit may have suffered catastrophic damage which is irreparable. We adhere to a 'no fix, no fee' policy which means that if we cannot repair a faulty unit, we do not make any charges. In these instances we would either return the unit, or dispose of it according to our environmental procedure.

How long do the repairs normally take?

Our typical turnaround time is 10-15 working days, however we often turn items around in less. If you need an item repaired very urgently, we offer an express service whereby, for a small premium, we will make every effort to turn your unit around in 24-48hrs.

Our target turn time for International repairs is 10 days but this is somewhat dependent on the logistics of the customer location.

How can you guarantee the unit is safe post repair?

We have full PAT and flash test facilities at our premises. All units which come in for repair are subject to a pre-repair insulation, isolation & earth bond test to protect our engineers, and a comprehensive post-repair insulation, isolation & earth bond test to provide peace of mind for the customer.

Can you supply diagrams and technical information for my power supply?

Although we have full legal access to documentation & schematics relating to the Farnell / Advance power supplies, the intellectual property owners (American Power Conversion) forbid us to pass this information onto any third parties. As we cannot risk litigation in this matter, we are unfortunately unable to offer any documentation for sale or otherwise.

Exactly what is included in your 'fixed price repair'?

We offer a standard repair price on all Farnell / Advance PSU's The standard price includes all minor parts and labour and includes a full test to the original specification. In the unlikely event that the unit should require major parts (e.g. windings, subassemblies) there may be an extra charge. In this case we would contact you prior to proceeding with any repairs.

Can you repair non-Farnell/Advance power supplies?

Yes, we have a great deal of experience of power supplies in general, both switch mode and linear and have successfully repaired many PSU's from other manufacturers. We are happy to discuss your requirements at any time, but may be unable to offer a fixed price repair on such items prior to an initial investigation.

Can you supply spare parts for my power supply?

Yes, we hold a large inventory of Farnell / Advance PSU spares & components. Please contact us with your requirements.

Do you offer a calibration service?

Yes, we are fully equipped to calibrate your items and can offer this service where required at a very competitive cost.

Do you only repair power supplies?

We specialise in the PSU field, however, our knowledge extends to other associated equipment such as systems & shelves and a variety of other Farnell test equipment and instrumentation such as electronic loads, oscilloscopes and signal generators. We have comprehensive information on many of these items and are certain we can assist you with any queries you might have.
