How do I know if my UPS has a bypass switch?
If your system comes with a static UPS switch it will be clearly labelled on the product description, it generally comes as standard with an on-line UPS but it’s worth making sure.
A maintenance bypass switch of the external variety will need to be bought separately in most instances and fitted by one of our technicians. If your electrical systems are mission-critical, for example in manufacturing or healthcare, we will likely advise fitting an external switch when you first purchase your UPS system and which product is the best fit for your needs.

UPS Bypass Frequently Asked Questions (FAQ)
What is static bypass?
Static Bypass is the line which effectively joins the input supply to the output and continues to support the load without going through the UPS system.
How does a UPS Bypass Switch work?
UPS Static Bypass switches allow the normal UPS normal operation to be circumvented, in cases of an overload or fault situation. A properly designed system should enable this to be performed without loss of power to the load.
What is UPS Bypass Mode?
UPS Bypass mode is when you switch the circuit from going through the UPS to going around or bypassing it. A manual bypass switch is used to remove the UPS system from the circuit for servicing or maintenance or if it is no longer working correctly. An automatic transfer switch functions in the same way as a manual, but will also switch the UPSs load to mains electric automatically if the UPS experiences an internal failure.
What is bypass switch in inverter?
As a static inverter is a more specialised version of a UPS system it works the same way, the Bypass switch allows a static inverter system to be bypassed if there is an issue or maintenance is required.
What is UPS THDi?
Total Harmonic Distortion (THDi) is a measurement of the harmonic distortion and is the ratio of the sum of the power of all harmonic components to the power of the fundamental frequency. THDi is also used to characterise the power quality of electric power systems and the linearity of audio systems.
