21、ITHOUT PERMISSION FROM UL Preface This is the common UL and CSA Standard for Solid-State Dimming Controls. It is the second edition of both CSA-C22.2 No. 184 and UL 1472. This common Standard was prepared by a Task Force comprised of members representing CSA, UL, NEMA (National Electrical Manufactur

22、ers Association) and the EFC (Electro-Federation of Canada). This standard includes all items presently covered in C22.2 No. 184-M1988 except the following: a) Lighting controls without integral switching (disconnecting control). b) Devices used as table mounted unit to which a portable luminaire ca

23、n be temporarily connected. c) Devices installed in lampholders. d) Devices permanently installed in the supply line of a lamp. e) Direct plugin devices. The above will be accommodated either in a new edition of C22.2 No. 184, or in future revisions of this standard. Note: Although the intended prim

24、ary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. Level of Harmonization This Standard is published as an identical standard for UL and CSA. An identi

25、cal standard is a standard that is the same in technical content except for conicts in Codes and Governmental Regulations. Presentation shall be word for word except for editorial changes. Interpretations The interpretation by the SDO of an identical or equivalent standard shall be based on the lite

26、ral text to determine compliance with the standard in accordance with the procedural rules of the SDO. If more than one interpretation of the literal text has been identied, a revision shall be proposed as soon as possible to each of the SDOs to more accurately reect the intent. CSA Group Effective

27、Date The effective date for CSA Group will be announced through a CSA Informs or CSA Group Certication Notice.

30、L NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Solid-State Dimming Controls 1 Scope 1.1 These requirements cover permanently installed devices, hereafter referred to as dimmers, that employ a dimming function intended for control of lighting loads of the magneti

31、c ballast, transformer, electronic ballast, self-ballasted lamp, tungsten-lament type, or light-emitting-diode (LED), and are intended to be installed in a wallbox or are provided with an enclosure for ush or surface mounting in accordance with the Canadian Electric Code, Part 1 (CEC), and the Natio

32、nal Electrical Code (NEC), ANSI/NFPA 70. 1.2 These requirements cover dimmers, other than touch dimmers, rated 600 volts ac or less, for installation on a 20-ampere or less branch circuit. 1.3 These requirements cover touch dimmers rated 120 volts ac or less for installation on a 20-ampere or less b

33、ranch circuit. 1.4 These requirements cover dimmers, including touch dimmers, and electronic switches, having a minimum power rating of 300 watts incandescent or 300 volt-amperes in increments of 50 watts or 50 volt-amperes. 1.5 Devices may have additional current ratings based upon the additional l

34、ighting loads as specied by the manufacturer. 1.6 A device incorporating other functions (for example, speed control) in addition to a dimming function is investigated on the basis of compliance with the applicable requirements for the dimming function in this Standard as well as requirements for th

35、e other functions in the applicable standards. 1.7 These requirements do not cover dimmers that use only a resistor or a transformer to perform the dimming function. 1.8 These requirements do not cover modular, cabinet or console type constructions. 1.9 These requirements do not cover dimmers intend

36、ed primarily for use in theaters. Dimmers for use in theaters are covered by the Standard for Industrial Control Equipment, UL 508/CSA C22.2 No. 14.

37、 UL 2 Denitions 2.1 The following denitions apply in this Standard. Actuating member Part of the operating mechanism that is used for the dimming control functions. This member may also be used to operate the air-gap switch. CFL Compact Fluorescent Lamp. CCFL Cold Cathode Fluorescent Lamp. Dimmer A

38、device intended to change lighting to various intensities. For the purposes of these requirements, the term dimmer refers to all products covered by this Standard. Electronic ballast A ballast, generally involving high-frequency switching that is controlled by active components (transistors, thyrist

39、ors, and the like), and with the lamp ballasting impedance provided by a series capacitive or inductive reactance appropriate for the high switching frequency. “Ballast” also refers to other drivers or supplies that operate lamp technologies other than uorescent. Electronic switch A solid-state devi

40、ce that performs strictly an on-off function and meets the requirements of this standard including the air-gap switch requirement. Grounding/bonding conductor A conductor that is dened in the National Electrical Code (NEC) as an Equipment Grounding Conductor, and a conductor that is dened in the Can

41、adian Electrical Code (CE Code), Part I, as a Bonding Conductor. Lamp, self-ballasted A device such as a CFL, CCFL, LED, etc. that is provided with a lamp base and incorporating a nonreplaceable light source and any additional elements such as an electronic ballast necessary for starting and stabili

42、zing operation of the light source, which cannot be dismantled without being permanently damaged. Off position The air-gap switch is in the open position. Opposite polarity A difference of potential between two points where shorting of these two points would result in a condition involving overload,

43、 rupturing of printed wiring board tracks, components, fuses, or the like. Touch dimmer A device using circuitry for touch actuation in accordance with Clauses 4.9 and 5.13. Examples of such circuitry are non-isolated sensing or conductively connected dead metal. Type I dimmer A dimmer in which the

44、air-gap switch is used to energize preset lighting levels. Type II dimmer UL A dimmer with an air-gap switch that opens and closes the load circuit at the minimum output voltage setting only. Type IIa dimmer A dimmer with an air-gap switch that opens and closes the load circuit at the maximum output

45、 voltage setting only. Type III dimmer A dimmer incorporating solid-state components providing preestablished rectied output settings. Type IV dimmer A dimmer not covered by Types I III.
