1. 동작 주파수 코어 손실 변신 로봇 주파수와 밀접한 관계가 있으므로 사용빈도에 따라 설계하여 사용하여야 한다. 이 주파수를 작동 주파수라고 합니다.
2. Rated power Under the specified frequency and voltage, the 변신 로봇 can work for a long time without exceeding the output power of the specified temperature rise. 
3. Rated voltage refers to the voltage allowed to be applied to the coil of the 변신 로봇, which shall not be greater than the specified value during operation. 
4. Voltage ratio refers to the ratio of the primary voltage to the secondary voltage of the 변신 로봇, and there is a difference between the no-load voltage ratio and the load voltage ratio. 
5. No-load current When the secondary of the 변신 로봇 is open, there is still a certain current in the primary, and this part of the current is called the no-load current. The no-load current consists of the magnetizing current (which produces the magnetic flux) and the iron loss current (caused by core losses). For a 50Hz power 변신 로봇, the no-load current is essentially equal to the magnetizing current. 
6. No-load loss refers to the power loss measured at the primary when the secondary of the 변신 로봇 is open. The main loss is the iron core loss, followed by the loss (copper loss) generated by the no-load current on the copper resistance of the primary coil, and this part of the loss is very small. 
7. 효율은 1차 전원 P1에 대한 2차 전원 P2의 비율을 백분율로 나타냅니다. 일반적으로 높을수록 rated power of the 변신 로봇, 더 높은 효율성.
8. Insulation resistance Indicates the insulation performance between the coils of the 변신 로봇 and between the coils and the iron core. The level of insulation resistance is related to the performance, temperature and humidity of the insulating material used.
