18、lecommunications Standard (ETS) defines the product-specific specific performance criteria and operating conditions for power supply equipment intended to be used within a public telecommunication network. Such equipment includes: - central power plant; - end of suite power supplies: - uninterruptib

19、le power supply (UPS); - stabilized AC power supply; - and other dedicated telecommunication network power supplies. This ETS specifies the operating conditions and the minimum compliance criteria for such equipment. The applicable EMC tests, the method of measurements and the limits are specified i

20、n ETS 300 386-1 l, from which the EMC requirements are selected taking into account the priority of service provided by the equipment under consideration. The environmental classification used in this ETC refers to ETS 300 386-1 I. The requirements of this ETS do not cover those cases where a potent

21、ial source of interference which produces individually repeated transient phenomena or continuous phenomena is permanently present, e.g., a radar or broadcast site in the near vicinity. In such cases it may be necessary to use special protection applied to either the source of interference or the eq

22、uipment interfered with, or both. Power supply equipment which is uniquely associated with or integrated in other equipment is outside the scope of this ETS. Equipment for cabled distribution systems for television and sound signals as defined in EN50083-2 26 is outside the scope of this ETS. 2 Norm

23、ative references This ETS incorporates by dated and undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these

24、 publications apply to this ETS only when incorporated in it by amendment or revision.

The AC secondary voltage may be either: - - a stabilized AC supply derived from a DC primary supply (e.g. where the power supply is an inverter); or derived

38、 from the AC primary supply (e.g. a stabilized power supply used where the quality of the primary supply is not sufficient to feed telecommunication equipment.

42、e EUT operates as intended without degradation of performance below the minimum level defined in the relevant subclause of the present ETS, and without loss of function.
