Note: The pinyin letters in the series code have different meanings even if they are the same letter in different positions. Please pay attention to this when compiling and identifying.
4. The specification code is composed of the characteristic data of the converter: (1) The characteristic data of the rectifier is:
Rated output current (ampere)/rated output voltage (volt) (2) The characteristic data of the inverter is:
Rated output frequency (hertz)/rated output voltage (volt) × rated output current (ampere) (3) The characteristic data of the medium frequency induction heating power supply is: rated output frequency (hertz or kilohertz)/rated output power (kilowatt) (4) The characteristic data of the asynchronous motor excitation speed control device is: speed ratio/rotor voltage (volt) × rotor current (ampere) JB/T1505-1975
Note: For converters with voltages higher than 1000 volts, kilovolts are allowed to be used as the voltage unit. 5. The special environmental condition code is composed of pinyin letters, see Table 3. For products that meet the normal use conditions in JB1500-75 "General Technical Conditions for Semiconductor Power Converters", this code is not included in the model. Table 3
