Loadstar - Emergency lighting AC/AC static inverter

The Loadstar range of AC/AC static inverter units offer the opportunity to create a discreet emergency lighting system, utilising suitable standard mains luminaires without modification. Small or decorative compact luminaires can also be easily incorporated.

Loadstar AC/AC systems offer many benefits, including higher light levels in emergency mode, as all lamps in the luminaire are usually energised by the emergency supply.

Mains voltage and lower currents enable cables of smaller cross-sectional area to be used with low voltage AC/DC systems, without unacceptable levels of voltage drop. The proven and reliable modular design ensures a cost-effective emergency lighting solution.

Latest news and insights

Loadstar – Energy efficient standby operation

The Loadstar range of AC/AC static inverter systems are designed specifically for long term sustainability, reduced carbon footprint and reduced running cost without compromising on the products performance criteria.

Due to the passive standby operation of the inverter only operating when required, the quiescent running power is minimised while maximising equipment life and reduced running cost.

Loadstar is also 3rd party certified to EN50171, meaning you can rest assured that it can be depended upon if the worst were to happen.

System operation

eaton-ceag-el-cps-service-techniker-anlage-1500.jpg
  • In mains healthy condition, the system charges the batteries and stores power, ready for emergency operation.
  • In mains healthy condition, the power to luminaires designated for emergency use is supplied from the normal mains, via a bypass contactor inside the cubicle. This may be switched, using a “maintained lights” switch (optional extra) or by use of a remote switch connected to terminals provided.
  • In the event of a mains failure, the system provides emergency power to dedicated mains slave or designated standard mains luminaires, until mains power is restored (or for the rated duration of the system in the event of extended mains failure).
  • Sub-circuit monitoring and hold off relays can be added to the system to energise the emergency luminaires in the event of a localised mains circuit failure, if the ACM1 module is not used.
  • Local change-over switching can be achieved using an ACM1 module, controlling single or multiple luminaires (if fed from common switched mains supply - max load 750VA). The system will then supply normal mains power or emergency power via the inverter, dependant on the status of mains supply at the static inverter.
  • Output voltage, from the system via the inverter, is 230V AC nominal.
  • Standard mains luminaires require no modification to operate with the static inverter (unless ACM1 change-over module is fitted integrally). All lamps in multi-lamp luminaires will be lit during mains failure, unless separate control gear is provided for individual lamps.

Standard specification

Cubicles

  • Zinc coated steel panels with powder coat RAL7032 light pebble grey finish

  • 3 standard size cubicles, for combined charger/inverter/battery, charger/inverter only or battery only
  • Small systems require only one cubicle. Larger systems housed in multiple sets (see selection tables)
  • Electrical control gear and battery compartments are segregated, with lockable access door(s)
  • Battery compartments supplied, where appropriate with separate tiered sections, to enable ease of electrolyte level inspection
  • Separate fixed fascia panel for mounting control/display panel
  • Option of open battery racks on larger systems

Battery Charger

  • Solid state, constant voltage charge control module
  • Fully automatic
  • Full recharge within 24 hours of a rated discharge
  • Recharge to 80% capacity within 12 hours, complying with EN50171
  • Manual boost switch on systems with vented battery cells
  • Current limit facility, preventing overcharging or damage to the system in the event of battery failure or fault.
  • Outputs have low AC ripple currents for maximum battery life and in compliance with EN 50171.
  • Input protection by MCB.

Battery
