About Us

QES Limited was founded in 1990 as a high quality repair and engineering services business specialising in electronic power conversion equipment (Power Supplies). Twenty years later these Quality Electronic Services are very well known across a wide range of customers and markets world wide.

As well as producing and repairing our own products we repair power supplies made by any other manufacturer; companies like Astec, Advance Power, Coutant, Cosel, Lambda, Liteon, Weir and XP Power plus hundreds of others. If thats not enough we also provide replacements for obsolete power supplies, our brochure explains this service and lists the models already available.
