A new range of advanced lighting control units has been launched by Polaron Controls. The Lightlink dimmer racks make use of the latest IGBT (insulated gate bipolar transistor) technology. IGBTs provide a single step solution towards dimming lighting loads that require control gear to be either leading or trailing edge controlled.

Polaron's Lightlink Universal Dimmers automatically detect the load type for each connected channel and adapt to leading or trailing edge without any operator intervention. In addition to phase control, each dimmer channel has a switched 1-10V output for controlling HFR ballasts.

Added benefits of IGBT technology are the removal of noisy chokes and dynamic short circuit, overload and thermal protection. If a short circuit occurs, the dimmer will safely shut down until the short is removed. There is also no nuisance tripping of MCBs due to current inrush.

Polaron has incorporated Universal Dimming technology into both standard 4 and 12 channel dimmer racks and also dual plug-in modules that fit into custom racks. Plug-in modules allow hot-swapping of power modules and provide for a cost effective upgrade of previously installed modules in existing projects.

"Polaron's new technology will render the thyristor and triac obsolete for dimming applications. As a leading player in the lighting control market, we continue to show sustainable growth through the use of innovative technology," stated Polaron's chief executive Joe Stelzer.

Designed and manufactured in the UK, Polaron lighting controls can integrate fully with audio-visual, building management, security and HVAC systems.

Notes to editors:

Over the last 30 years, Polaron Controls has undertaken a wide range of high profile lighting projects, including the Hong Kong Convention Centre, The Burj Al Arab in Dubai, London's Royal Opera House and the Hilton's flagship Metropole Hotel.

Parent company Polaron Engineering is a privately held UK engineering group focusing on niche engineering markets. The group is expanding rapidly, with revenue increasing by 50 per cent over the last year.
