Welcome to the Online Shop for Surge and Overvoltage Protection.


Overvoltage, Undervoltage and Surge Protection 

Protection for your mains supply. Wire in between the inlet socket on the side of the Caravan or Motorhome and the vehicles mains consumer unit. That way it can prevent damaging supplies reaching the sensitive electronics within your mains installation and equipment connected to it.

Programmable with no time delay or delays to allow a supply to settle the unit has a built in relay to cut out the supply if the supply voltage coming into the van is to high or to low. Also the surge protection circuit prevents damage to the connected equipment thereby extending its life.

Electronic equipment has its own surge protection built into it however units I have seen so far has a type of device that ultimately is sacrificial failing on higher voltages or doing its job by absorbing the unfortunately quite normal surges an fluctuations in the supply. When the device fails it short circuits often with smoke and tripping of the protective device it is connected to. Of course this also prevents the device operating!!


I have been looking for a long time for a device big enough to supply a mobile installation. Now with a 30Amp device I have one big enough to supply the 16Amp installation the caravan and motorhome is.
