Description

INTEGRATED POWER SUPPLIES AI RATED POWER 1 TO 7,5 KVA, 220/240 V PROTECTION DEGREE IP20 The power supply of telephone plants and FM/TV relay stations has always entailed numerous problems and specific needs which are difficult to meet, among them: to assure the safety of operators working on the plants, according to the law; to assure continuity of operation to the plants; to build a compact distribution system for all loads usually present in relay stations; to limit the costs of installation and management; to allow a cheap and effective technical assistance. SAFETY FOR OPERATORS To ensure the safety of operators it is also necessary that: The premises hosting the telecommunications equipment are accessible only to specialized personnel. All equipment has live parts protected by barriers that can only be removed using tools. The electrical systems are built in the Rule of Art. CONTINUITY OF OPERATION The continuity of operation required by an automatic repeater, often installed in practically inaccessible sites, must satisfy a variety of requirements, ranging from the prevalently technical to the economic, limiting the need for intervention on the equipment. The first problem to arise, and probably also the most difficult to tackle, is that of protection against atmospheric discharges, practically omnipresent in repeaters on account of the sites they have to be installed in. Due to the coupling of electromagnetic fields and the conduction in cables, the effect of lightning spreads for several kilometres from the impact point.
