17、 ANSI_ANSLG C82.14-2006 First Edition 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 semiconductors to control lamp starting and operation. The ballasts
18、 operate from multiple supply sources of 600V maximum at a frequency of 60 hertz. The output frequency of electronic ballasts may be of some frequency other than 60 hertz. This standard only covers lamp operating current frequencies from greater than 60 hertz up to 400 hertz (some exclusionary frequ
19、ency 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 C78.43 lamp standards. 2.

The preferred design center supply voltage ratings for ballasts covered by this standard are: 120, 127, 208, 220, 240, 277, 347, and 480V. 4.2 Supply Voltage Range. The designated supply voltage ra
27、nges 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.

Ballasts are commonly designated to start and operate lamps over one of the following lamp ambient temperature ranges: (1) 10C (50F) and above (2) -15C (5F) and above (3) -30C (-22F) and above (4) -40C (-40F) and

Ballast Performance 5.1 General. All measurements necess
31、ary 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 requirements for the designated position of the appropriate lam
32、p 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 designed to meet the starting parameters of 5.3.1 and 5.3.2. 5.3
33、.1 Starting Voltages. 5.3.1.1 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 for electronic ballasts specifi
34、ed 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 voltage and at rated input frequen
35、cy, 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 rated input frequency, a ballast
36、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 rated input frequency, a ballast
37、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, which meet the starting requirements of section 1.6.1 of the Lamp Dat
38、a sheets of ANSI C78.43, within the requirements of the appropriate electronic ballast section. 5.3.6 Warm-up Time. Ballasts shall warm up lamps, which meet the warm-up requirements of section 1.6.2 of the Lamp Data sheets of ANSI C78.43, within the requirements of the appropriate electronic ballast
39、 section. 2006 American National Standard Lighting Group, in affiliation with NEMA Page 7 of 12 ANSI_ANSLG C82.14-2006 First Edition 5.4 Ballast Input. A power line circuit having a maximum of 450milli-ohms and 100h of impedance shall be used to determine compliance with this section. 5.4.1 Input Cu
40、rrent Harmonic Distortion. Caution, there 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
41、 the root-mean-square of the fundamental and harmonic components. The 3rdharmonic and odd multiples of the 3rdharmonic (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 bal
42、anced 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. 5.4.2 Inrush Currents. There is a need to control inrush current transients caused by
43、capacitor charging. A ballast (circuit) shall limit inrush current transients by meeting one of the following requirements: For any lamp, a ballast must have a maximum allowable input capacitance as specified in Table 1 or incorporate a means of limiting the aggregate peak inrush current amplitude a
44、nd duration for each value of steady state current to less than the values shown in Table 2. Pulse duration must meet the limits for I2t in Table 2 where I is the inrush current measured in rms amps for the pulse duration period and t is the pulse duration period of two milliseconds at 10% of the pe
45、ak current level. Table 1. Bulk Energy Capacitances System (Volts) 120 277 347 Bulk energy capacitance: F per Ampere of steady state current 175 125 TBDTable 2.

47、06 American National Standard Lighting Group, in affiliation with NEMA Page 8 of 12 ANSI_ANSLG C82.14-2006 First Edition For ballasts and lamp systems that do not meet the limits above, the ballast manufacturer must specify in its literature the circuit loading that meets the above guidelines. For t
48、he purpose of this requirement, “input capacitance” and “bulk capacitance“ are defined as the total capacitance ( 20%) charged by the line at ballast turn-on. 5.5 Ballast Output 5.5.1 Lamp Operating Power. When operated at its rated voltage and frequency, a ballast shall deliver to a lamp, with its
49、voltage within the tolerance of the appropriate lamp in the ANSI C78.43 lamp standards, a wattage within 5% of its nominal wattage. Wattage excursions greater than 5% increase the risk of noticeable lamp-color variation. 5.5.2 Power Regulation. When operated at its rated frequency and with any supply voltage within +/- 10% of the rated supply voltage, the ballast shall
