Vaisala WSP150 Surge Protector no Connectors for WXT530 Series WXT520 and WXT510

Surge Protector WSP150 is a compact transient overvoltage suppressor designed for outdoor use. It can be used with all Vaisala wind and weather instruments.

Features:

• Superior, three-stage transient surge protection
• Tolerates up to 10 kA surge currents
• Noise filtering against HF and RF interference
• Robust structure
• IP66 housing
• Both differential and common mode protection on each channel
• 2 power and 2 data channels
• Can be used with all Vaisala wind and weather instruments

Key Benefits:

• Versatile - Can be used with all Vaisala wind and weather instruments.
• Superior protection - The WSP150 offers three-stage protection against surge currents up to 10 kA entering through the power and signal cables.
• Robust structure - Reliable investment.

Superior protection

A lightning strike nearby may induce a high voltage surge, which the integral transient suppressor of the instrument may not tolerate. Additional protection is needed, especially where frequent and severe thunderstorms are common and where cables longer than 30 m (98 ft 5 in) are used. Also use WSP150 if you have unshielded, open-wire lines. WSP150 offers 3-stage protection against surge currents up to 10 kA entering through the power and signal cables.

Powerful technology

WSP150 has 4 channels, 2 of which are dedicated to power lines and 2 for data lines. Each channel uses a 3-stage protection scheme: first there are discharge tubes, then voltage dependent resistors (VDR), and finally transient Zener diodes. Between each stage, there are either series inductors or resistors. Both differential and common mode protection is provided for each channel: across the wire pairs, against the operating voltage ground, and against the earth. WSP150 also provides an additional filter for blocking the HF-conducted interference.

Applications

Vaisala recommends using WSP150 when wind and weather instruments are installed on top of high buildings or masts and in open grounds, that is, anywhere with an elevated risk of lightning.
