  • Prevent Power Surges with Full Spectrum Surge Protection
    are essential components of many modern automation systems; however, they are also particularly susceptible to power surges from voltage and current spikes. In these systems, serial device servers are key communication gateways that connect the broader Ethernet network with specific serial devices
  • Application Note: Combing GDTs and MOVs for Surge Protection of AC Power Lines
    , etc. -- but regardless of the name, an understanding of their characteristics and the operation of the various protection devices available is necessary to design an effective protection circuit.This Application Note will illustrate how to design high performance, cost-effective surge protection
  • Surge Protection Technology Used in Power over Ethernet (PoE) Protection 9.(.pdf)
    and PoE+ in open-air environments are subjected to large surge currents, and protection must be installed to prevent damage. This paper will outline the components, standards and grounding used in PoE protection. The two main standards for PoE are IEEE 802.3af and 802.3at. These standards relate
  • Current Sense Resistors
    Sudden current or voltage changes are often hazardous to electronic products. For example, transients or surges that reach microprocessor or memory components can destroy those expensive parts, and wipe out critical programming and data. Many electronic products now include surge protection
  • Tech Brief: CATV Equipment Protection (.pdf)
    that exceed 6000 V and surge currents up to 5000 A. CATV station protectors should be able to withstand overvoltages that exceed 5000 V and surge currents up to 1000 A. The SIDACtor devices illustrated in Figure 3.47 through Figure 3.50 meet these requirements. The following regulatory requirements may
  • Understaning Ground Resistance Testing
    In today's rapidly changing world of technological advances, good ground is more important than ever to prevent costly damage and downtime due to service interruptions and inoperative surge protection caused by poor grounds. Ground systems offer protection from natural phenomenon such as lightning
  • Windfarms - Grounding with SAN-EARTH
    Wind turbines are located in open spaces often in rocky mountainous areas where soil resistivity is high making them particularly vulnerable to lightning currents that may threaten human life or damage expensive equipment. Partnered with surge protection devices (SPDs), a low resistance path
  • Application Note: Data Line Protectors
    be protected against overvoltages that can exceed 1500 V and surge currents up to 50 A. Data Line Reference Circuit Figure 3.57 shows how a SIDACtor device is used to protect low voltage data line circuits.
