Maintained Central Battery Unit

maintained central battery

The term “maintained” can be a little confusing when referring to Central Battery Units. One would think that since all the units contain batteries that they would all maintain the supply.

These, of course, do provide a supply from the batteries when the mains fails but the term “maintained”, when speaking of CBUs, refers to the output when the mains supply is present and healthy.

The maintained supply is typically an AC voltage of the same voltage level as the DC supply provided by the batteries. Different voltage levels and DC options can be provided if required.

The maintained supply is used to power the luminaries when the mains supply is present.
On interruption of the mains supply, the DC power from the batteries is supplied through the same output terminations.

In this way, the luminaire being supplied can be illuminated all the time and this is where the term “Maintained” comes from. The lighting used is maintained in a lit condition in the presence of the mains supply and in the event of its failure.

Non-maintained Central Battery Unit

non maintained central battery unit

A non-maintained Central Battery Unit has the same features in respect of the battery backed up supply and control gear for emergency lighting as the maintained type unit.

The principle difference is that when the mains supply is present there is no output from the unit.

The luminaire used with such a unit are likely to only be lit during a period where the mains supply has failed.

Standby Central Battery Units

standby central battery units

Standby Central Battery Units are typically provided in a non-switched output format.

The output supply is fed from the batteries at all times and the batteries are charged via a controlled charging circuit when the mains supply is healthy and present.

Typically such units are used with luminaires which have the capability to switch between a mains supply source and the Standby Central Battery Unit provides an instant source of DC power.
