Constructed with Littelfuse thermally protected varistors, the LSP05 and LSP10 provide robust surge current handling capability. A built-in thermal disconnect function that provides additional protection from catastrophic failures and fire hazards, even under the extreme circumstances of Varistor end of life or sustained overvoltage conditions.
The LSP05 series is configured with parallel connections, while the LSP10 module is available with either parallel or series connections. The series connected version of the LSP10 is the world's first indicating surge arrestor capable of handling surges of up to 20,000A in outdoor LED applications. With the parallel connected versions, an indicator wire can activate an LED to tell maintenance personnel when to replace the SPD in order to ensure the luminaire remains protected. The LSP10 series connected version cuts luminaire power off to provide a clearly visible indication the SPD should be replaced.
The LSP05 and LSP10 surge protection modules offer these key benefits: • Protecting outdoor LED fixture investments with maximum lightning surge current ratings of 20,000A (LSP10) and 10,000A (LSP05).
- Internal varistors are thermally protected to prevent failure due to end-of-life or continuous overvoltage faults.
- Clear indication of SPD replacement prevents future surge damage to luminaire.
- IP66 waterproof and dust proof design allows for flexibility in outdoor installation locations, inside or outside of luminaire, top or bottom at lighting pole, in transformer box or on distribution panel.
- Indication wire options make it easy to implement an indicating/ monitoring circuit for SPD replacement.
- These devices meet UL1449 Type 4 Component Assembly requirements and are compliant with IEC 61643-11 Class II and EN 61643-11 Type 2, so are suitable for use in LED lighting fixtures around the world.
- Their compact form factor (48 x 48 x 30mm) makes them easy to mount inside a luminaire; mounting tabs simplify installation and replacement.
