Harmer + Simmons / AEG power solutions / SAFT  PSU repairs and refurbishment.

APS offer skilled repair service for all models of AEG Power Solutions / SAFT / Harmer and Simmons DC power supplies and rectifiers. You can see a list below of those models we have successfully repaired before. Our team can also refurbish obsolete or failed units. DC power supplies are usually found at the heart of many industries; manufacturing, telecommunications, utilities, defence and transport sectors. Unfortunately, a PSU failure can bring your business to its knees, particularly when the supply is obsolete and unavailable.

Harmer + Simmons was a British company that specialised in the telecoms side of the DC power supply business. It played a major role, manufacturing rectifiers for the telecom revolution that Britain experienced in the 1960s and 1970s. These rectifiers powered vast banks of batteries that ran telephone exchanges in the event of a mains power failure. You can see more detail about the BT Approved Harmer and Simmons models, including replacement options at www.160rectifier.com.

The ownership of Harmer + Simmons, like many power supply companies, changed hands over the years by acquisition.
