Novaris SDD DINsafe Surge Diverters offer powerful performance at domestic MSB and industrial DBs. The SDD diverters are housed in DIN compliant, failsafe metal enclosures and are fully compliant to AS/NZS1768-2007 and to AS/NZ3000 wiring rules.

HOW it works

The Novaris unit works as a example to protect sensitive electrical equipment by controlling the maximum voltage potential across the positive and Negative terminals of the switch board in a local area or the appliances, this unit protects against EMP voltages produced because of the lighting and also surges from the lighting.
as a example on a normal 24 volt system if the voltage rises to 34 volts then a short is placed across the wires to reduce the voltage and hold it at 30v and dumps this to the earth /ground system on the boat, once the voltage drops below 30v then the short is releases, This short can only be held for a few Nano seconds 8/20us with amperage’s upto 12,000 amps but its enough to protect the equipment in Most cases. after this hit the unit may have to be replaced but there is a fault display included.

This How it works is a basic overview of the devices operation, in Laymans terms that non electrical people will understand.
