T2, Class C, Class II AC Surge Protection Device SPD for PCB mounting

LSP has developed a series of socket bases as an on-board printed circuit board (PCB) the solution to optimally protect electronic equipment with efficient surge protection while keeping the cost for installation down. With the constant demand for increased reliability of power systems, electronics manufacturers expect comprehensive turnkey solutions
that are ready to be installed but are effectively designed with optimum functionality. The key benefits of the PCB Socket Series are cost and space efficiency, elimination of manufacturing lead times, and maximum equipment protection ensured.

The SLP20P range (Type 2) is designed to protect the AC side of photovoltaic inverters.
The single-pole module must be soldered directly on the PCB, in parallel to the AC network.
The pin-out is the same whatever the Uc voltage.

• For use with maximum continuous operating voltage (UC) up to 850 V modules
• Sensitive and reliable remote signaling contacts
• Fault indicator, green-no green
• Compact profile for printed circuit board (PCB) mounting
• In: 10 kA, Imax: 20 kA
• IEC 61643-11 compliance


In order to reach the relevant specifications, the PCB where the SLP20P or SLP20P-PV SPDs will be used must be carefully designed by the customer.

Q1: Selection of surge protector

Al: The grading of the surge protector (commonly known as lightning protection) Is assessed according to the IEC61024 subdivision lightning protection theory, which is installed at the junction of the partition. Technical requirements and functions differ. The first-stage lightning protection device is installed between the 0-1 zone, high for the flow requirement, the minimum requirement of EN 61643-11 / IEC 61643-11 is 40 ka (8/20), and the second and third levels are installed between the 1-2 and 2-3 zones, mainly to suppress the overvoltage.
