Central Battery Systems

Central Battery Systems
(50V and 110V)

A wide range of Central Battery Units and Static Inverter Units are available to suit specific project demands. All units utilise high quality ten year life Valve Regulated Lead Acid batteries or low maintenance twenty five year life Vented Nickel Cadmium batteries and the systems are specifically designed for emergency lighting applications.

Slave versions of the standard luminaire range can be ordered plus standard mains luminaires can be converted for connection to Central Systems by using the 50 volt and 110 volt slave inverters.

LD-CB emergency control gear

LD-CB – Central Battery LED Emergency Control Gear

Conversion of all modern LED luminaires for connection to central battery emergency supplies.

The LD-CB emergency LED module allows maintained operation of high power LED modules or arrays, when utilising the standard mains voltage LED control gear in-line with the central battery powered emergency LED control module.

The LD-CB central battery module allows for maintained, hold-off or slave operation of high power LED modules or arrays.

LM-CB Emergency Control Gear

LM-CB 110 – Central Battery LED Emergency Control Gear

The LM-CB 110 central battery emergency LED control gear allows for hold-off or slave operation of low power LED modules. The emergency gear is designed to operate from either a 50V or 110V AC/DC central battery supply, and for hold off operation an unswitched 230V AC mains supply would be required as well.

SafepowerSafePower - dimensions

Low Power Static Inverter Systems (SafePower)

The SafePower range offers a choice of mini static inverter power supplies for the operation of a wide range of mains voltage lighting equipment (eg mains voltage GLS & compact fluorescent lamps, small HID, LED etc). The SafePower units are supplied with robust enclosures and utilise high quality 5 year life Valve Regulated Lead Acid batteries. The mini static inverters can be supplied with maintained outputs or used solely as standby supplies.

SIM 240 Changeover Module

On medium to large projects it can be advantageous to provide emergency lighting using a static inverter connected to a number of the existing mains luminaires.

In these installations it is necessary for the normal supply and the static inverter supply to be selected by an automatic switching device within or external to the luminaire. Some suppliers offer a standard 230V AC change-over relay for this purpose but this ignores the fact that a free running static inverter is not tied to the grid frequency and will therefore be out of phase or in a worst case situation could be in anti-phase with the normal switched supply.

When a relay tries to switch between these supplies there is a tendency for the relay to suffer from arcing between the normally open and the normally closed contacts resulting in a temporary short circuit between the two out of phase supplies. This will cause external circuit protection to operate (fuses and/or circuit breakers) and will ultimately destroy the relay.

In extreme cases it can also damage the static inverter.

The SIM240 static inverter module is designed to eliminate these switching problems. The SIM240 utilises two interposing relays for the two supplies and introduces a time delay of approximately 500m sec between breaking the normal supply and connecting the static inverter supply. This sequence is reversed upon restoration of the monitored 230 volt supply when the SIM240 immediately breaks the static inverter supply and then after a similar time delay reconnects the normal lighting supply.

A dimming isolation facility is incorporated as standard for use with dimming ballasts to enable full light output to be achieved in the emergency condition.

SPS Static Inverter Central Battery Systems

SPS Static Inverter Central Battery System units provide a 230 VAC supply in the event of loss of the normal mains supply. SPS is designed to operate third party mains luminaires at full output as either maintained, switched maintained or non-maintained luminaires for 3 hours.

SPS features five models with maximum power output ranging from 99W to 574W.

Compact SPS units incorporate an inverter which provides and maintains the voltage of 230 VAC ±3% (50Hz) on all output circuits. These are either from the normal mains supply or, in the effect of a mains failure, the integral 2 x 12 volt 10 year Valve Regulated Lead Acid batteries.

SPS complies with the requirements of BS EN 50171 (central power supply systems) and BS EN 62034 (automatic test systems for battery powered emergency escape lighting).
