ANSI C82.4-2017 Page i AMERICAN NATIONAL STANDARD A
12、pproval of an American National Standard requires verification by The American National Standards Institute, Inc. (ANSI) that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. An American National Standard implies a consensus of th
13、ose substantially concerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly, and materially affected interests. Substantial agreement means much more than a simple majority, but no
14、t necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The existence of an American National Standard does not in any respect preclude anyone, whether s/he has approved the standard or not, from manufactur
15、ing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. It is intended as a guide to aid the manufacturer, the consumer, and the general public. The American National Standards Institute, Inc., does not develop standards and will in no circumstances g
16、ive an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute, Inc. Requests for interpretations should be addressed to the secretaria

26、lectrical Manufacturers Association ANSI C82.4-2017 Page 1 2017 National Electrical Manufacturers Association 1 Scope This standard provides specifications for and operating characteristics of magnetic ballasts for metal-halide, mercury, high-pressure sodium, and low-pressure sodium lamps. The balla
27、sts operate from multiple supply sources of 600 volts maximum at a frequency of 60 hertz. They may be designed for operation in either indoor or outdoor conditions. The following types of ballasts are excluded from this standard: a. Ballasts consisting of resistance only. b. All electronic ballasts
28、that use semiconductors to control the lamp power. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard. At the time of publication, the editions indicated were valid. All standards are subje

36、ted in this American National Standard are given in ANSI C82.9. 5 Ratings 5.1 Preferred Supply Voltage The preferred design center supply voltage ratings for ballasts covered by this standard are 120, 208, 240, 277, 347, 480, and 600 volts. 5.2 Supply Voltage Range The designated rated supply voltag
37、e ranges specified in the various parts of Clause 5 shall be made available by the manufacturer in ballast catalogs or other technical literature. 5.3 Load The rated load of a ballast shall be specified in terms of the wattage and lamp designation (in accordance with C78.380), for the lamp it is int
38、ended to operate. 5.4 Lamp Starting Temperature Ballasts are commonly designated to start and operate lamps over one of the following ambient lamp temperature ranges: (1) 10C (50F) and above (2) 15C (5F) and above (3) 30C (22F) and above (4) 40C (40F) and above 5.5 Ballast/External Starting-Aid Capa
39、citive Load Rating The external starting-aid capacitive load rating shall be the maximum value of capacitance with which the external starting-aid may be loaded and still meet all minimum pulse requirements. The capacitive loading of the ballast/external starting-aid/lamp system varies widely with d
40、ifferent wiring methods and ANSI C82.4-2017 Page 3 2017 National Electrical Manufacturers Association materials. Recommendations should be sought from the external starting-aid or ballast manufacturer, or both. 6 Ballast Performance 6.1 General All measurements necessary to determine compliance with
41、 the ballast performance requirements of this standard shall be made in accordance with ANSI C82.6. 6.2 Lamp Operating Position Ballasts may be designed for the operation of lamps in the vertical, horizontal, or other designated position. The ballast shall be tested with a reference lamp in its desi
42、gnated operating position. Lamps labeled as U, HBU, or BUH, should be operated in the base up orientation. 6.3 Starting Voltage When operated within the designated supply-voltage range including 92% to 105%1of its rated supply voltage95% to 105% for high reactance autolag and reactor ballastsa balla
43、st shall provide root-mean-square (rms) and peak voltages that equal or exceed the appropriate minimum values specified in applicable ANSI lamp standard listed in Clause 2. For lamps requiring starting pulses, a ballast shall provide pulse voltage, width, repetition, and position within the limits s
44、pecified in the applicable ANSI lamp standard listed in Clause 2. 6.4 Starting Current When operated within the designated supply voltage range including 92% to 105%1of its rated supply voltage (95% to 105% for high reactance autolag and reactor ballasts), a ballast shall provide starting current in
45、 compliance with the appropriate requirements as specified in the applicable ANSI lamp standard listed in Clause 2. 6.5 Additional Starting and Sustaining Requirements Ballasts for metal-halide and high-pressure sodium lamps shall also meet additional starting and sustaining requirements within the
46、designated supply voltage range, including 92% to 105%1of their rated supply voltage (95% to 105% for high reactance auto lag and reactor ballasts) as specified in the applicable ANSI lamp standard listed in Clause 2. 6.6 Lamp Operating Power When operated at its rated supply voltage, a ballast shal
47、l deliver to a reference lamp a wattage within the specified percentage (given in the following table) of the wattage delivered to the same reference lamp in the identical position by the appropriate reference ballast. Both the reference ballast and the ballast under test shall have the same rated f
48、requency. In this test, both ballasts shall be operated at their rated supply voltage. 1 The voltage limits of 92% to 105% of rated supply voltage closely approximate the range of utilization voltages provided by public utility systems.
