Vaisala Surge Protector WSP152 is a compact transient overvoltage suppressor. You can use it with Vaisala WXT transmitters to protect the host computer against surges entering through the USB port. A nearby lightning strike can induce high-voltage surge not tolerable by the protection of the USB cable or the port itself. Additional protection is needed in regions with severe thunderstorms, especially when long line cables (>30 m) are used.

Vaisala recommends using a surge protector in installations on top of high buildings or masts and on open grounds, and in all sites with an elevated risk of a lightning strike. |
The surge protector provides additional filtering for blocking the HF-conducted interference induced into the cables in installations.
The surge protector has four channels: two dedicated for power lines and two for data lines. Each channel uses a 3-stage protection scheme with gas discharge tubes, voltage-dependent resistors, and transient zener diodes. Both differential and common-mode protection is provided for each channel: across the wire pair, against the operating voltage ground, and against earth.
WSP152 has a plastic housing with metal reinforcement. You can mount it on a wall, on a table edge, or to Ø 30 mm … 102 mm (1.18 … 4.02 in) pole masts with the provided adjustable mounting clamp. A cable gland is provided for the optional heating power cable (HTG).
