1. Use

JBK3 series machine tool control transformer is a new product manufactured by reference to the German Siemens company prototype, and conforms to relevant international and national standards such as VDE0550, IEC204-1, IEC439, GB5226.

JBK3 series machine tool control transformer is suitable for AC 50~60Hz, output rated voltage does not exceed 200V, input rated voltage does not exceed 500V, as the mechanical equipment of all walks of life, general electrical control power supply and work light, signal light power supply.

2. Model and its meaning

3. Scope of application

BKZ series rectifiers are made up of BK transformers and rectifier components. The transformer is suitable for the power supply with the primary side voltage of 220V or 380V AC 50Hz. The output voltage is rectified by the transistor rectifier flow element and output DC, which is used for battery charging and the AC power to DC power supply is used on the equipment.

4. Installation, use and maintenance

1) The use of the rectifier transformer must comply with the conditions specified in Article 2;

2) Before installation, carefully check the parameters on the nameplate and confirm that they are correct before installing and using;

3) Connect the line according to the mark, and after the check is correct, it can be powered on;

4) Avoid collision and storage in a dry and ventilated place during transportation. Do not get wet to ensure the performance and use of the product.

5. Normal working conditions

1) Ambient air temperature:

1 The upper limit of ambient air temperature does not exceed +40 ° C;

2 The average value of ambient air temperature 24h does not exceed +30 ° C;

3 The lower limit of ambient air temperature is not lower than -5 °C.

2) Altitude: the altitude of the installation site does not exceed 2000 meters;

3) Atmospheric conditions: The relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is +40 °C, and the relative humidity can be higher at lower temperatures.
