  • Combing GDTs and MOVs for Surge Protection of AC Power Lines (.pdf)
    , 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
  • 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
  • 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
  • Surge-Trap and the Different kA Ratings
    Power surges occur daily and the equipment within your own facility accounts. for roughly 80% of all disturbances. As a result, Surge Protection Devices. (SPD) are being used at more facilities to protect sensitive control equipment. However, there is some confusion when trying to understand
  • 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
  • Secondary Telecom Protection (.pdf)
    premature failure of equipment exposed to environmental hazards (Figure 3.53). Secondary protectors should be able to withstand overvoltages that can exceed 800 V and surge currents up to 100 A. Figure 3.54 illustrates a SIDACtor device selected because the associated peak pulse current (IPP) is sufficient
  • 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
  • Surge Protection Devices and Uninterruptible Power Supplies (.pdf)
    IEEE Standard 1100-2006 (Emerald Book), Section 8.6.5 (p. 302) "Lightning and other transient voltage and current-producing phenomena are harmful to most UPS equipment and to its service electronic load equipment... Therefore, it is recommended practice that both the input circuit to the UPS
