JBK3 series transformer is applicable to AC 50/60hz, withthe rated output voltage not exceeding 220V and the rated input voltage not exceeding 500V.It is used cas the control power supply of mechanical equipment in all walks of life, general electrical appliances and working lighting and signal lamps.

JBK5 series transformers are a state-of-the-art transformer range our company introduced from Germany in the mid-1990s. Based on the domestic JBK3 series transformers, we have further absorbed the advantages of foreign similar products over the years, and adopted the terminal block structure designed with advanced foreign techniques—integrating terminals with the bobbin. This design has upgraded the protection class to IP2LX, preventing accidental contact with the circuit. We use domestic IT cold-pressed terminal blocks, whose wiring method enables a higher wiring density.

1) Bring in technology of Germany.

2) Maximum protection grade reach IP2LX, can stop touch circuitoccasionally.

3) Adopt cold-pressure connection terminal which can improve conne ction intensity

4)Adopt excellent corrode-proof material, which greatly inmprove the reliability of earth connection

5)Used for machine with input voltage less than 500V, output voltage 220V and frequency 50/60Hz

6) Comply with VDE0550, IEC204-1, IEC439, JB5555, GB5226and certificated by CE.

JBK6 series transformer is the latest transformer serieintroduced by our company from abroad. On the basis of JBK5 transformer, a new generation of transformer jbk6 transformer has been developed. Its shape, installation dimension and applicationoccasion are the same as JBK5 transformer.

1) The terminal screw is bigger than JBK5 which make it moree convenient to connect

2) It has short-circuit and heat protection and is more reliable.

3) Adopts technology of vacuum painting and imported insulation material, which make its

ability more steady.

JBK7 series transformer is a "expensive" family transformer developed by our company on the basis of JBK5 transformer. The overall dimensions and installation dimensions of jbk7 are the same as those of JBK5.In terms of material selection,more materials with excellent current performance are selected, which improves the insulation levelof transformer to level F. its no-load performance and load performance are better than thoseof JBK5 series products. It is a well deserved energy-saving and environmental protection prodluct.

1) The connection terminal adds plug-in quick conne ction function

2) When required by customers, it can be equipped with short circuit and thermal protection devices, which is safer and more reliable;

3) The whole impregnation process is adopted, and the insulation grade is f, which improves the ability of the product to prevent moisture,mold and salt fog.It can be used in dry tropical, humid and hot zones and other harsh environments.
