KNOWLEDGE BASE

The Secure Power knowledge base aims to give you the information you need to navigate the jargon and deliver straightforward advice around the terminology used within uninterruptible power systems.

RECTIFIER

A Rectifier is a component of the UPS electronics that is responsible for converting AC (Alternating current) power into DC (Direct current) power.

The Rectifier is responsible for the process of rectification within the UPS. Rectification is a core function, allowing the conversion of AC power provided by main electricity to be used to charge the DC batteries attached. Without a functioning Rectifier, the UPS would not be unable to function causing it to enter bypass and present a corresponding error code.

AC

Alternating current present in mains power alternates direction at a fixed rate, 50hz in the UK. The alternating current is generated in a sinewave. This sinewave has equal distribution between the positive direction and the negative direction.

DC

In contrast to AC power, DC power has no waveform. Graphed over time the current appears as a solid line. The DC power present in UPS is centred around the batteries present within the electrical system.

Power Secured DC

While a rectifier is not a mechanical device the components that create its electrical system include capacitors that contain an electrolyte. This electrolyte undergoes a chemical reaction during normal use, over time this capacitor will require replacement to continue operating effectively and ensure proper operation.
