[. . . ] www. vaisala. com WSP150 Surge Protector The WSP150 offers three-stage protection against surge currents up to 10 kA entering through the power and signal cables. Powerful technology The WSP150 has four channels, two of which are dedicated to power lines and two for data lines. [. . . ] Also use the WSP150 if your cable length exceeds 30 m or you have unshielded, open-wire lines. Superior protection A lightning strike nearby may induce a high voltage surge, which the integral transient suppressor of the instrument may not tolerate. Therefore, additional protection is needed, especially where frequent and severe thunderstorms are common and where long cables of more than 30 m are used.
