Vaisala WSP152 Surge Protector

Vaisala WSP152 is designed to protect the host PC against surges entering through the USB port. This is common when the USB port is continually used for interface.  For example, a nearby lightning strike may induce a high voltage surge, which is not tolerated by the protection of the USB cable or the port itself. Therefore, additional protection is needed, especially where frequent and severe thunderstorms are common and where cables longer than
30 m are used. Note that the USB connection of a PC is for indoor use only.  Vaisala WSP152 offers three-stage protection against surge currents of up to 10 kA that may enter through the USB cable or the port.


Consider the Vaisala WSP150 for surge protection via communications.
