Function and Usage
The JBK3, JBK4 series machine tool control transformers are suitable for AC circuits with a frequency of 50Hz, as control power, lighting power, and signal power for machine tools, industrial automation control systems, power equipment, machinery, and electrical equipment. Conforms to the standard: Q/ZT 205.
Detailed Parameters
| Parameter Category | Parameter Item | Parameter Value |
|---|
| Normal Operating Conditions and Installation Conditions | 3.1 | Altitude does not exceed 2000m. |
| 3.2 | The upper limit of ambient air temperature is 40°C, and the lower limit of ambient air temperature is -5°C. (When users need to use in environments higher than 40°C or lower than -5°C, it needs to be specified at the time of ordering, and special customization is required). |
| 3.3 | At the maximum temperature of 40°C, the relative humidity of the air does not exceed 50%, and at lower temperatures, higher relative humidity is allowed, for example, up to 90% at 20°C. Special measures should be taken for occasional condensation caused by temperature changes. |
| 3.4 | The installation environment should be well-ventilated, free from pollution, corrosive gases, dust, explosive media, flammable substances, and combustible gases; there should be measures against rain, water, and snow, and no water vapor. |
| 3.5 | The installation location has no vibration and impact vibration. |
| 3.6 | The power supply voltage waveform is a sine wave, the total harmonic content of the input power supply voltage does not exceed 5%, the even harmonic content does not exceed 1%, and the total harmonic content of the load current does not exceed 5%. |
