NEMA SSL 1-2016 Page 4 2016 National Electrical Manufacturers Association Section 2 LED Driver Ratings 2.1 Common Voltage Ratings (Nominal (Input

37、or Supply) Voltage and Frequency) The preferred design-center supply-voltage ratings for drivers covered by this standard are 120, 127, 208, 220, 230, 240, 277, 347, and 480 VAC at 50 or 60Hz. 2.2 Supply (Input) Ratings The LED driver ratings and markings should include: a. The maximum nominal input

38、 voltage b. The maximum input current c. The maximum input power d. The input frequency (e.g. 50/60 Hz) Note: A LED driver with a dynamic input voltage range (e.g., 120 to 347) should be marked with the input current at the minimum nominal input voltage and at the maximum nominal input voltage Any o

39、ther input current shall be in between these two extreme values. Additional input information may be provided in the driver manufacturer catalogue and data sheets. 2.3 Led Load (Array, Module, or Package) The rated load of a driver shall be specified as noted below. a. Maximum output wattage of the

40、driver b. For drivers that supply a constant voltage, output voltage in volts ac or dc on the product label c. In any collateral publications (instructions, specifications), the output voltage in VDC shall include a tolerance band specified as a percentage (e.g., 24 VDC 5%) d. For drivers that suppl

41、y a constant current, output current shall be specified in amps on the product label e. In any collateral publications (instructions, specifications), the output current in amps shall include a tolerance band specified as a percentage (e.g., 5 amps 5%) f. For drivers designed to operate specific mod

42、ules or arrays, those modules and/or arrays shall be specified on the label and/or in the install instructions Note: The output rating and the maximum output capability are not usually the same. 2.4 Led Driver Operating Temperatures Drivers are designed to start and operate LED loads over a range of

43、 ambient temperatures. Due to variations of thermal transfer capabilities with fixture designs, the ambient temperature is not always an ideal way to specify product capability while the maximum Tcis a better measurement for application determination. The minimum ambient temperature and the maximum

44、Tctemperature and location should be clearly marked on the product label or product specification documents. NEMA SSL 1-2016 Page 5 2016 National Electrical Manufacturers Association Section 3 Driver Performance 3.1 General The LED driver shall maintain the specified performance throughout its lifet

45、ime under the operating conditions specified. The driver should be tested per the requirements in ANSI C82.16 2015. Note: If a driver can operate over a wider range of voltages or currents than specified, this should be identified by the manufacturer. 3.1.1 Operating Conditions For reliable operatio

46、n, a driver for LEDs shall be designed to meet the operating parameters of Section 3 when tested at a temperature of 25 5C. 3.2 Led Driver Input A power line circuit having a maximum impedance as specified by NEMA 410 shall be used to determine compliance with this section. 3.2.1 Operating Supply Vo

47、ltages When operated at any supply voltage between 90 percent and 110 percent of its rated supply voltage and at rated input frequency, a driver shall provide current and/or voltage regulation that equals or exceeds the values specified by the manufacturer. 3.2.2 Input Current Harmonic Distortion Th

48、e harmonic distribution of the input current shall comply with the requirements of ANSI C82.77-10-2015. 3.2.3 Input Inrush Current There is a need to control inrush current transients caused by capacitor charging. Inrush currents shall be limited as specified in NEMA 410. 3.2.4 Input Current The LED

49、 driver input current, expressed in amps, shall be measured at the nominal input voltage of 120, 208, 277, 347, or 480 VAC, be connected to a branch circuit as described above in Clause 3.2, and have connected to the output the maximum load whether it be a LED array, module(s), or package(s). The LED driver input current for a dynamic range LED driver should be measured at the minimum nominal driver input voltage and at the maximum nominal driver input voltage, e.g., at 120 and 277 V for a LED driver rated for a 120 to 277 V range. 3.2.5 Input Pow
