JBK Control Power Transformer are suitable for AC circuits with frequency of 50Hz/60Hz. They are used as control power, local lighting and indicator lights power of general electrical equipment in various types of machine tools and machinery equipment.
Control Power Transformer Meets the standard: Q/ZT 205. We are a professional Control Power Transformer manufacturer.

The Control Power Transformer can work reliably under the following environmental conditions.
1. The altitude is not more than 2000m.
2. The upper limit of ambient air temperature is 40°C, and the lower limit is -5°C (when it needs to be used at higher than 40°C or below -5°C, it is necessary to specify the special order when ordering).
3. When the maximum temperature is 40°C, the relative humidity is not more than 50%, and high relative humidity can be allowed at a lower temperature, such as 90% at 20°C. Special measures should be taken for the occasional condensation due to temperature change.
4. Non-explosive medium, and there is no enough gas to corrode metal and destroy insulation, and conductive dust.
5. There are no significant shaking and shock vibrations.
6. The place that is not eroded by rain and snow.

JBK Control Power Transformer is a updated product of bk control transformers. It is manufactured using imported materials and advanced technology. It has the features of reliable operation, low energy consumption, small size, safe wiring, and wide applicability.
