■
Overview
Type 3 overvoltage protection adapters for insertion in a
5
socket outlet protect electronic loads against overvoltages from
main power supplies.
However, overvoltages do not just reach loads over power cables.
Telecommunication devices for TAE, ISDN/RDS and RJ12
connection, televisions or radios with aerial connection or satellite
radio connection are all connected to a further power supply
system which may allow overvoltages to reach – and damage –
devices.
■
Benefits
•
All type 3 overvoltage protection adapters are fitted with an
LED as a visual status and fault indication
•
The protection circuit is subject to continuous thermal monitoring.
This ensures constant safe operation for the operator.
