Surge Protection Solutions for Positive Train Control

Positive Train Control (PTC) promises a new level of safety and efficiency for U.S. railroads, and to deliver on its promise, reliable data transfer must occur. One component of ensuring the uninterrupted data transfer is surge protection, which has to meet new demands as the components of PTC continue to advance in sensitivity and complexity.

Several new technologies are available to effectively and reliably protect from surges and thus contribute to the PTC goal of preventing collisions, derailments, and consequent injuries and casualties to roadway workers, as well as costly disruptions to traffic flow. The newer, highly sensitive digital equipment used in the PTC systems demand new, advanced surge protection technologies to ensure long-term operation.

PTC-related, highly sensitive electronic equipment requires a more advanced approach to surge protection. Research over the past decade has led to a hybrid design that takes advantage of the best operating characteristics of voltage limiting and voltage switching devices, resulting in state-of-the-art, two-stage protection products.

PolyPhaser Introduces SpikeGuard™ Gas Tube Surge Protector Series

PolyPhaser has released a new line of straight gas tube surge protection products under the SpikeGuard™ brand. SpikeGuard is leading a revolution in the straight gas tube protection market by bringing together a smaller profile, superior RF performance, competitive pricing and immediate availability through TESSCO.

4.9 Public Safety Surge Protection

The construction of the PolyPhaser AL-LSXM series has allowed surge protection to be utilized in mission critical applications such as 4.9 public safety. The AL-LSXM has a high degree of surge immunity, doesn’t have a finite life span like gas tube alternatives, and has excellent RF characteristics throughout the frequency band.

Since the AL-LSXM is fully weatherized and lightweight it can de deployed in locations that have minimum access and do not receive periodic maintenance such as rooftops, outdoor wall mounts, and tower-top sites. These characteristics make the AL-LSXM the prime candidate as a primary lightning protector for customers looking for the ultimate protection of their 4.9 public safety system.

GX Series GPS DC-Pass Protector for Sensitive Equipment

The PolyPhaser GX series is a DC-pass protector in the 800MHz to 2,500MHz range designed to protect sensitive tower-top electronics such as tower-mounted amplifiers, GPS antennas, power boosters and anything else that receives a DC voltage on the center pin of the coax.

SX Series High-Powered UMTS, CDMA, GSM Protector

The PolyPhaser SX series are DC-blocked protectors for high-powered applications from 800MHz to 2,500MHz and low-powered applications between 2GHz and 6GHz. The SX is available in 7/16in DIN, as well as, 'N' connectors and has low return loss and insertion loss in addition to an industry low let through voltage.

AC/DC Surge Arrestors

PolyPhaser manufactures a complete line of surge arrestors for coaxial lines, data lines and AC/DC circuits, as well as single point grounding panels. Our major product lines include the DAS, GX, SX and HF for protecting coaxial lines, the NX and IX for data lines, the IL and PM for protecting AC/DC applications and PEEP products for grounding.

NetGuard High-Speed Data Protection

The NetGuard from PolyPhaser is a RJ45 plug-in data platform protector for backhaul and networking equipment. The NX can be used on DSL, POE, ISDN, Ethernet, and E1/T1 lines and is molded in a housing with integrated mounting lugs, making installation of these devices simple.
