A list of organizations represented on this committee can be obtained on request to its secretary.
5、From1 January1997, all IEC publications have the number60000 added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references
6、Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in th

This standard specifies a class A and class B pulse output device. For special applications seeAnnex E. 1 Scop
27、e This part of IEC62053 is applicable to passive, two-wire, externally powered pulse output devices to be used in electricity meters as defined by the relevant standards of technical committee13 (seenormative references) as well as future standards for static VA-hour meters. Such pulse output device
28、s are used to transmit pulses, representing a finite energy quantity, to a receiver (e.g.a tariff device). 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC62053.

Two types of pulse output devices are defined in this standard: pulse output devices class A for long range transmission; pulse output devices class B for short range and low power consumption. The pulse output shall generate a number of pulses proport

The time between two successive pulses t OFFis defined in Figure B.1 with t OFF $ 30ms. 4.1.3.4 Transition time (t T ) The transition time (rise time or fall ti
40、me) is the time from one state to the other, including transient effects, e.g.contact bounce. The transition time shall be less than5ms (see Figure B.1). 4.2 Mechanical requirements 4.2.1 General The features of the pulse device shall comply with all mechanical requirements stated in the standard ap
