ANSI C82.14-2016 Page i 2016 National Electrical Manufacturers Association AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by The American National Standards Institute, Inc. (ANSI) that the requirements for due process, conse

13、nsus, and other criteria for approval have been met by the standards developer. An American National Standard implies a consensus of those substantially concerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreemen

14、t has been reached by directly, and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The existence o

15、f an American National Standard does not in any respect preclude anyone, whether s/he has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. It is intended as a guide to aid the manufacturer, the consu

16、mer, and the general public. The American National Standards Institute, Inc., does not develop standards and will in no circumstances give an interpretation of any American National Standard.

24、l Manufacturers Association ANSI C82.14-2016 Page 1 2016 National Electrical Manufacturers Association 1 Scope This standard provides specifications for and operating characteristics of low-frequency square wave electronic ballasts for metal halide lamps. Electronic ballasts are devices that use sem

25、iconductors to control lamp starting and operation. The ballasts operate from multiple supply sources of 600 V maximum at a frequency of 60 Hz. The output frequency of electronic ballasts may be of some frequency other than 60 Hz. This standard covers only lamp operating current frequencies from gre

26、ater than 60 Hz up to 400 Hz (some exclusionary frequency ranges may apply). An electronic square wave ballast is defined as an electronic ballast whose operating lamp current waveform is essentially a square wave with defined rise/fall times stated in the ANSI C78.43 lamp standards. 2 Normative Ref

34、s of terms that apply specifically to the subject treated in this American National Standard are given in ANSI C82.9. For additional definitions, see ANSI/IEEE 100. 4 Ratings 4.1 Preferred Supply Voltage. The preferred design center supply voltage ratings for ballasts covered by this standard are 12

35、0 V, 127 V, 208 V, 220 V, 240 V, 277 V, 347 V, and 480 V. 4.2 Supply Voltage Range. The designated supply voltage ranges specified in the various parts of this standard shall be made available by the manufacturer in ballast catalogs or other technical literature. 4.3 Load. The rated load of a ballas

36、t shall be specified in terms of wattage and the lamp type characteristic letter and electrical characteristic number (ANSI C78.380) of the lamp it is intended to operate. 4.4 Lamp Starting Temperatures. Ballasts are commonly designated to start and operate lamps over one of the following lamp ambie

37、nt temperature ranges: a. 10C (50F) and above b. 15C (5F) and above c. 30C (22F) and above d. 40C (40F) and above 4.5 Ballast/Starter Capacitive Load Rating. The ballast/starter load rating shall be the maximum value of capacitance with which the ballast/starter may be loaded and still meet all mini

38、mum pulse requirements. The capacitive loading of the ballast/starter/lamp system varies widely with different wiring methods and materials. Recommendations should be sought from the starter or ballast manufacturer, or both. ANSI C82.14-2016 Page 3 2016 National Electrical Manufacturers Association

39、5 Ballast Performance 5.1 General. All measurements necessary to determine compliance with the ballast performance requirements of this standard shall be made in accordance with ANSI C82.6. 5.2 Lamp Operating Position. The ballast shall be tested with a reference lamp that meets the electrical requi

40、rements for the designated position of the appropriate lamp in the ANSI C78.43 lamp standards when operated with a reference ballast specified in that standard. 5.3 Starting Conditions. To obtain reliable starting, a low-frequency square wave electronic ballast for metal halide lamps shall be design

41、ed to meet the starting parameters of 5.3.1 and 5.3.2. 5.3.1 Starting Voltages. When operated at any supply voltage between 90% and 110% of its rated supply voltage and at rated input frequency, a ballast shall provide root-mean-square (RMS) and peak voltages that equal or exceed the minimum values

42、for electronic ballasts specified in the ANSI C78.43 lamp standards. 5.3.2 Pulse Requirements for Lamps Requiring an Auxiliary Starting Circuit (Ignitor). 5.3.2.1 Ignition Pulse Characteristics for Square Wave Ballasts. When operated at any supply voltage between 90% and 110% of its rated supply vol

43、tage and at rated input frequency, a ballast shall provide the ignition characteristics for electronic ballasts specified for the appropriate lamp in the ANSI C78.43 lamp standards. 5.3.3 Starting Current. When operated at any supply voltage between 90% and 110% of its rated supply voltage and at ra

44、ted input frequency, a ballast shall provide the starting current in compliance with the minimum and maximum requirements of the appropriate lamp in the ANSI C78.43 lamp standards. 5.3.4 Hot Restrike Time. When operated at any supply voltage between 90% and 110% of its rated supply voltage and at ra

45、ted input frequency, a ballast operating a bare reference lamp in a 25C ambient shall restart the lamp within 15 minutes after the ballast supply voltage is cycled “off then on,” long enough to drop out the lamp. 5.3.5 Starting Time. Ballasts shall start lamps that meet the starting requirements of

46、section 1.6.1 of the ANSI C78.43 Lamp Data sheets within the requirements of the appropriate electronic ballast section. 5.3.6 Warm-up Time. Ballasts shall warm up lamps that meet the warm-up requirements of section 1.6.2 of the ANSI C78.43 Lamp Data sheets within the requirements of the appropriate

47、 electronic ballast section.ANSI C82.14-2016 Page 4 2016 National Electrical Manufacturers Association 5.4 Ballast Input. A power line circuit having a maximum of 450 m and 100 h of impedance shall be used to determine compliance with this section. 5.4.1 Input Current Harmonic Distortion. Caution, t

48、here is a requirement for the protection of the neutral wire in 3-phase, 4-wire “Y”-connected systems where the neutral wire is the same size as the phase wire. It is also to minimize voltage distortion on the power lines. A non-sinusoidal (distorted) waveform is the RMS of the fundamental and harmo

49、nic components. The 3rd harmonic and odd multiples of the 3rd harmonic (9th, 15th, 21st, etc.) add in the neutral conductor on the 3-phase, 4-wire “Y”-connected system. The fundamental and other harmonics will cancel in the neutral conductor with a balanced system load. The fundamental and other harmonics will cancel in the neutral conductor with a balanced system load. The harmonic distribution of the input current shall comply with the requirements of C82.77-10-2014. 5.4.2 Inrush Currents Refer to NEMA 410-2015. ANSI C82.1
