LSPD devices are designed to protect FlashGuard medium intensity strobe lighting systems. The LSPD provides both a grounding solution and surge suppression for these installations.
LSPDs minimize exposure to lightning damage through tower light wiring, a lightning path that is commonly overlooked at communications sites. Without the use of a LSPD, the interconnecting cable between the strobe's flashhead and the power supply provides a direct path that can allow damaging surges and transients to enter the shelter.
Sites with the LSPD installed have proven reliability. Sites with previous lightning problems have recorded hundreds of lightning strikes after LSPD installation, with no damage to the power supply or communication equipment.
Response Time: Less than 5 µs.
Current Withstand: 40 kA per mode. IEEE C62.41 8x20 µs short circuit waveform.
Circuitry: LSPDs are series wired with parallel protection. Robust MOVs protect all circuits. A large ground plane bonded to a #2 copper ground lug provides a strong electrical/mechanical discharge point.
LSPD units are installed between the flashhead and the power supply, providing protection for both the lighting power supply and the telecommunications equipment installed at the site.
The LSPD units are supplied in a NEMA 4X outdoor enclosure. The protectors should be mounted on the tower above the ice bridge, before the cable turns to enter the shelter. The first level of protection forces any induced voltage on the cable's shield to tower ground. All lines then pass through a surge suppression device before continuing to the power supply.
Detailed installation instructions are included with each unit and should be adhered to for optimum protection. If requested, we will provide installation instructions for the model you are considering in advance.
