Part 11: Particular requirements for electronic inverters and converters for high frequency start tubular discharge lamps (pencil lamps) This part specifies the special requirements for electronic inverters and converters for commercial frequency cold cathode discharge lamps. Such inverters and converters are used in signal equipment using discharge tubes and are directly connected to a power supply voltage of 1000V or 50Hz below 1000V AC or 1000V self-driving. The output voltage is 1V~1CV. The value of 1i is not specified in the input, and the value can be 15cx The following two types of converters and frequency converters are specified, Class A and Class B requirements: A converter or frequency converter: The frequency range is 0-5kHz, the output and peak value of the final return shall not exceed 5000V, the input current is 25mA (effective value) and the output current is 50mA (sample value). The power supply voltage does not exceed 250V or 250V at 0Hz or 60Hz. Due to the limitation of the power supply and power rating, the output power of the A converter or frequency converter shall not cause electric shock hazard. In Japan, the output voltage can reach 5V.
Class B inverter or frequency converter: refers to the inverter or frequency converter that operates with a negative output voltage of no more than 5CV, a negative output voltage of no more than 100V between the terminals within the frequency range of Hz100kHz, and a maximum output current of 200A (effective value) and 400mA (peak value). 1: The output inductor of Class B inverter or frequency converter needs protection. Note: In Japan, the output voltage of Class B inverter should not exceed 5V. The secondary output group should not be grounded. In order to verify the safety of the inverter or frequency converter, their performance must be checked: However, due to the current characteristics of the neon lamp, this part specifies the reference voltage to ensure repeatable test results. The maximum rated operating temperature of the group is not applicable to this part. 2 Normative reference documents
