JBK Series Control Transformers

Normal operating and installation conditions
1. The altitude does not exceed 2000m.
2. Ambient air temperature:
The upper limit of the ambient air temperature does not exceed +40°C.
The average value of the ambient air temperature over 24 hours does not exceed +35°C.
The lower limit of the ambient air temperature is not lower than -5°C.
3. The relative humidity of the air is not more than 90%.
4. The ambient air does not contain gases or dust that can corrode metals or damage insulation.
5. During use, prevent collisions and severe vibrations, and prevent erosion from water, rain, and snow.
6. The power supply voltage waveform is approximately a sine wave.
