db Broadcast Enables UK DAB Roll Out

dB Broadcast is supplying its Cardinal intelligent Mains Distribution Unit (iMDU) for the UK roll out of DAB transmitter systems, being managed by Arqiva.

The Cardinal iMDU can change over between mains supply and uninterruptable (UPS) supplies in the event of a power outage at remote unmanned sites. It can switch off non-essential devices selectively after a user configurable delay in the event of a mains supply failure.

The DAB roll out is already in progress, having started early in 2014 and planned to run for another year. The Cardinal iMDU has been designed for EMC immunity EN55103 category E5: 'Heavy industrial environment and environments close to broadcast transmitters'.

Other unique features of the Cardinal iMDU that were utilised as part of Arqiva's system design include use of the iMDU as a GPI-to-Ethernet interface for telemetry, and its external temperature and humidity sensing for environmental monitoring of the DAB transmitter equipment rack.

Tom Swan (pictured), Sales & Marketing Director of dB Broadcast, said: "We introduced the Cardinal iMDU in 2010 for just such high reliability applications as the DAB rollout.
"Its robust design is unique, and features include handling inrush currents of up to 200A at switch on combined with sophisticated features such as web user interface, full SNMP control and alarming plus e-mail alert messaging."
