Motorola PTP 300 - Manual (Page 28)

PTP SOLUTIONS GUIDE 8
Although Motorola’s PTP 300, 400, 500 and 600 Series radios are designed to withstand extreme
conditions, they are often mounted on high towers, frequently with external antennas, making the radios
prime targets for lightning strikes. The Motorola Fixed Point-to-Point Lightning Protection Unit (PTP-LPU)
is designed to protect a Motorola PTP 300, 400, 500 or 600 Series radio from the harmful effects of power
surges induced in the cables by nearby lightning strikes. By grounding the power surges before they can
harm the units, the Motorola PTP-LPU gives PTP radios the best protection from the harmful effects of
lightning, although 100% protection is neither implied nor possible.
pTp Lightning protection Unit (pTp-LpU)
product Description
The PTP-LPU is a high-speed, high-current, solid-state device that is encased in a rugged metal case
designed to hold up against ice, snow and rain and withstand winds up to 150 mph (242 kph). The projected
operational life of a PTP-LPU is 10 years, even when continually exposed to the elements. Because of its
small form factor and minimum number of components, the cost-effective unit is easy to transport and
install. As a replacement for the Transtector surge arrestor (ALPU-ORT), the PTP-LPU is priced for a fast
return on investment.
Because the units can be installed with new deployments or easily added to existing PTP radios, current
and prospective operators of a Motorola PTP network can reap the benefits of the PTP-LPU’s lightning
protection capabilities.
For more details, refer to the PTP-LPU’s specifications at the end of this document.
