Solar Surge Protection Devices
Littelfuse's SPD2 PV Series offers devices for solar string box and inverter applications, available in 1100 and 1500Vdc in the 3+0 configuration. Solar surge protection devices provide equipment protection from transient overvoltage events last micro-seconds within the solar industry.
Solar surge protection devices provide equipment protection from transient overvoltage events lasting micro-seconds, by limiting the overvoltage to the equipment during these events reducing costly damage and downtime.
