SVS for First Great Western

PRODUCT: SVS75-22, Voltright
HISTORY: 2011

The Sollatek SVS includes the following features:

Boosts low voltage and reduces high voltage.
SVS disconnects the load from the appliance by using an inbuilt Automatic Voltage Switcher, when mains stabilisation within acceptable limits is outside its capability (available as an option in 3 phase models).
Automatically reconnects the load, but only after the mains has remained within acceptable limits for a period of three minutes. This is to allow neutralisation of compressor gases, critical in such applications.
Wide voltage response range of 145V to 290V (-26% to 18%).
Incorporates intelligent delay to reduce off-time when the appliance has been switched off for over three minutes.
Uses a unique zero voltage switching technique to achieve clean pure stabilised power.
Full spike protection.
Frequency compensated measurements.
Frequency and voltage measurement smoothing in software to filter noise.
Fault detection – Senses unreasonable measurements and disconnects output.

The power supply on a train is constantly unstable; any change in speed will cause voltage fluctuation, as will traveling uphill or pulling a heavy load, as a result, this can cause power problems and glitches that may damage the on-board electronics equipment.

First Great Western (FGW) operate The Night Riviera, one of only two remaining sleeper train services on Great Britain’s railway network. The Night Riviera is a unique, luxurious and restful way to travel; the sleeping car provides compartments and beds for all its passengers. However, power stability issues prevented them from offering their customers an appropriate level of service.

FGW offers food and beverages to commuters which will need a combination of microwave energy and convected heat, however the power supply can become unstable and can risk of damage to the equipment. FGW were looking for a way to provide a power supply stable enough to enable them to fit a new combination microwave oven.

Sollatek Voltage Stabiliser (SVS) provided the perfect solution to this problem. The SVS monitors the mains voltage continuously; if the voltage rises and drops, the SVS will regulate the output to ensure the power reaching the equipment remains constant at 230V (±6%). With its wide input voltage range and extremely fast response time, the British designed SVS is the ultimate solid state voltage stabiliser for all domestic and industrial equipment from fridges, air conditioners and televisions right through to medical applications.

The single phase SVS75 amp unit that was supplied to FGW protects the new oven from varying voltage on the vehicle (typically 250V to 280V). This unit was very easy to install and the pre-drilled holes made it very easy to connect the electrical conduits from the vehicle. as the SVS has a very large capacity, the sleeper service is now considering connecting more equipment to it.
