27、rement, and testing of characteristics relevant to the use and application of lighting controls and electronic drivers, discharge ballasts, and self-ballasted lamps. This standard covers devices rated 120 Vac, 277 Vac, and 347 Vac intended to control electronic drivers, discharge ballasts, and self-
28、ballasted lamp loads up to 16 amps of steady state current. This standard does not cover or require additional testing for 15 A and 20 A general-use ac snap switches tested and listed in accordance with UL 20/CSA C22.2 No. 111, which includes a high-inrush tungsten lamp load endurance test. They hav
29、e been evaluated and determined to be compatible with the electronic drivers, discharge ballasts, and self-ballasted lamps as described in this publication. NEMA 410-2015 Page 2 2015 National Electrical Manufacturers Association Section 2 DEFINITIONS 2.1 BALLAST An auxiliary device used to obtain th
30、e necessary circuit conditions (voltage, current, and waveform) for the proper starting and operation of a particular discharge lamp(s) from a particular line voltage and frequency. 2.2 DRIVER A device composed of a power source and LED control circuitry designed to operate an LED package (component
31、), an LED array (module), or an LED lamp. 2.3 ELECTRONIC DISCHARGE BALLAST A ballast that uses solid-state electronic components to transform current at high frequency to obtain the necessary circuit conditions (voltage, current, and waveform) for the proper starting and operation of a particular di
32、scharge lamp(s) from a particular line voltage and frequency. 2.4 INRUSH CURRENT Input current of short duration during initial start-up that is much greater than the operating or steady state current. 2.5 PULSE WIDTH Pulse width, as defined in the context of this standard, is the time interval betw
33、een the leading edge and trailing edge of a pulse at a point where the amplitude is 10% of the peak value. 2.6 SELF-BALLASTED LAMP A device provided with a lamp base and incorporating a non-replaceable light source and any additional elements necessary for starting and stabilizing operation of the l
34、ight source, which cannot be dismantled without being permanently damaged.

38、ver, discharge ballast, or self-ballasted lamp (herein after collectively referred to as an electronic device) is based on the limits of the electronic device inrush current. The electronic device limits the inrush current by having a maximum allowable input capacitance as specified in Table 1 or by
39、 incorporating a means of simultaneously limiting both the peak current and the I2t to values not greater than those specified in Tables 2 and 3. The I2t values in Tables 2 and 3 are based on a pulse width of approximately 2 ms and 2.35 ms respectively, and the peak currents shown in Tables 2 and 3,
40、 and Figures 3 through 14. The values in Tables 1, 2, and 3 are additionally defined in ANSI C82.11 and ANSI C82.14. A lighting control having a rated current (steady-state current) and rated voltage in accordance with Tables 1, 2 or 3 can be tested as described in Section 5 to determine if the ligh
41、ting control is compatible with an electronic device that operates within the parameters defined by Tables 1, 2, or 3 shown below and ANSI C82.11 or ANSI C82.14. The inrush pulse is shaped by two main parameters: the bulk capacitance of the electronic ballast or LED driver and the system source impe
42、dance. See Figures 16 and 17. As the source impedance increases the peak current decreases. An electronic device connected away from the point of interconnection of the building will produce a lower inrush current because the impedance to the point of interconnection will be higher.

45、dy state current rating of the switch or lighting control being tested. The series coil values shown in Figures 3 through 14 are approximate only. They must be adjusted based on the input line characteristics of the test laboratory to achieve the peak currents listed in Table 2 and 3. The series coi
46、l shall be sized such that it does not saturate during testing and shall be able to handle the resulting power dissipation with less than 10C temperature rise. Peak current and pulse width are illustrated in Figures 2. Typical waveforms based on Tables 2 are illustrated in Figures 3 through 14. Figu
47、res 15 through 17 show the agreement between results from the computer simulation circuit (Figures A-4 and A-4A) and measurements on synthetic loads (Figures 3 through 14).
