Power Supply Repair

Switchmode has been providing a specialist repair and refurbishment service, with high quality, high yield repairs, in Sydney since 1984. We have a custom equipped facility backing our years of technical expertise and extensive knowledge of power supply topologies. Our integrated customer support and technical database allows us to repair power supplies with little technical information.

We repair all makes and models of power supplies. We service all industries including Defence, Medical, Telecommunications, Mining, Transportation and Industrial applications. Our repair processes have been developed to provide a cost effective and efficient repair/refurbishment solution. You can achieve an even more cost effective power supply repair by providing us with as much information as possible. We have the technical skills and information to repair your power supply.


At Switchmode we offer preventive maintenance as standard as it reduces the chance of catastrophic failure and extends the lifetime of critical equipment. Catastrophic failure can lead to irreparable damage. We recommend scheduled refurbishment to reduce unexpected downtime of critical equipment.


Switchmode uses purpose-built test equipment to validate repairs against target specifications. All test results are recorded and maintained on our database. Compliance reports are available on request. We provide 12 months warranty on parts and workmanship of all power supplies repaired. Specialised test equipment is designed and manufactured as required.


Switchmode provides a fully traceable calibration service in accordance with ISO17025 and accredited by NATA.

Additional calibration services can be provided outside the Switchmode NATA scope of accreditation.
