Wireless Network Base Station: AC and DC Power Line Circuit Protection Application Note
■Wireless network base stations need protection from overvoltage and overcurrents. These conditions are due to lightning strikes, power line accidents, and other disturbances. Most base stations are in remote, lightning-prone areas, where quick access and efficient repair is difficult and expensive. Using appropriate protective circuits and devices helps lower damage risk.
●Power Input Line Risks and Protection
■The primary sources of danger to wireless network base stations are lightning and power faults. A strike directly to or nearby the tower can produce high voltages and cause considerable currents to flow through the power input lines. Short circuits can produce similar surges to higher-voltage transmission lines and switching transients. The resulting damage will incur repair time, service downtime, and customer disruptions, service downtime and and disruptions to customers. The most appropriate protection for these power input lines is a combination of fuses and high-power TVS diodes installed in the AC power distribution box. Diodes installed in the AC power distribution box.
●Using appropriate protective devices improves reliability and minimizes field service calls.
■The Littelfuse high-power TVS Diode Series, including the AK, LTKAK, SMTOAK2, and SMTAK3, are specifically designed for applications that require high energy transient voltage protection.
