Name: BK control transformer model: BK BK (DK) control transformers series and machine tool control transformer is our company introduced foreign latest transformers series, by structure divided into shell, installation method can be divided into vertical. This series was on the basis of domestic JBK3 machine tool control transformer, developing a new generation of transformers. Control transformer is applicable to 50-60HZ, the output voltage is 220V, in the input circuit of rated voltage up to 660V, as industry machinery and equipment, general control of electrical power and lighting, signal power, to replace foreign 4AM, 4AT-type transformers. Detailing product features: a wiring screws, wiring easier and stronger, also have plug quick connect dual function; B, with short circuit and thermal protection device, using more reliable; C, transformers with consolidated dipping process, insulating materials made of imported material, insulation performance is more stable; D, 100~400VA can be installed with standard Rails method. JBK series machine tool control transformer is reference and prototype manufacturing of new products in foreign countries, VDE0550, IEC204-1, IEC439, GB5226, and other relevant international and national standards; JBK5 machine control transformer is applicable to 50~60Hz, the output voltage is 220V, enter the rated voltages up to 500V, as all sectors of the mechanical equipment, general control of electrical power and lighting, light power use. Use environment: 1 ambient air temperature-5 ° c to + 40 ° c, the highest monthly average temperature up to + 30 ° c; 2, the installation location is not more than 1000m above sea level; 3, air relative humidity in the ambient air temperature of +40 is no more than 50%, at lower temperatures can be compared with the relative humidity, most wet month average maximum humidity of 90%, at the same time of the month is the average monthly minimum temperature of + 25 ℃, and taking into account surface condensation due to temperature changes occur. Use: apply 50-60Hz in the circuit voltages up to 500V, usually used as a machine tool control or partial lighting lamps and LEDs of electrical power used, widely used in post and telecommunications, shopping malls, elevators, hospitals, schools, printing, securities, and so all need voltage normal occasions and large and medium industrial enterprises and mines workshop, part of the power supply and important equipment and stand-alone facilities. Structural characteristics: series machine tool control transformer can be divided into the shell of the structure, installation method can be divided into two types of vertical and horizontal. Note: the above parameters for reference purposes only, are subject to change, subject to the actual product; if you need special products, you can contact our customer service to build.
