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.
Process Control ProtectionNovaris SL range provides surge protection for most twisted pair signalling schemes. Ideal for the protection of PLCs, fire and security systems, telecommunications and telemetry systems, railway signalling, SCADA and other industrial monitoring and control equipment.Multistage failsafe designA high energy gas discharge tube (GDT) as primary protection plus series impedance and secondary components provide very robust surge protection with high transient suppression offering low let-through voltages.Two different earthing optionsWith two different base options the SL protectors offer either direct earthing via DIN rail, for the most effective, low impedance earth connection (-G base) or a connection via GDT to the DIN rail, offering isolation under normal conditions and equipotential bonding during a surge (-EC90 base).Slimline pluggable modulesThe plug-in design provides simple and rapid replacement and testing – no rewiring needed. This also provides a convenient method of field equipment isolation if required.1) LED indicates status of instrument loop
