Vaisala - WSP150
Vaisala Surge Protector no Connectors
A compact transient over-voltage suppressor designed for outdoor use. It can provide over-voltage protection for 2 power
supply lines and RS-422, RS-485, RS-232 serial communication or 2 mA loop lines.
It can be used with WXT530 series, WXT520 and WXT510, WMT700 (non-heated), WA15 Wind Set, WM30 Wind Set,
DSC211, and DST111. Also other instruments can be protected if the current consumption is less than 1.5A.
Install WSP150 close to the protected instrument (maximum 3 m). Vaisala recommends using surge protectors if:
• Your weather instruments are installed in areas with an elevated risk of lightning strike, such as on top of high buildings or
masts, or in open areas
• Your cable length exceeds 10 m
• You have unshielded, open-wire lines
