JMB Transformer(JMB-5kVA)

Specifications

Application

  JMB,BJZ,BZ and DM series single - phase and three - phase lighting transformer It is suitable for AC circuit of 50~60Hz, widely applied in electronic industry, industrial and mining enterprise, worked as control power supply for usual circuit of machine tool and mechanical equipment and as power supply for safety lighting and indicator lamp.

Working conditions 

1.Ambient temperature: -15°C~+40°C
2.Altitude: <1000m
3.Relative humidity: <90%
4.Environment exists without gas, steam, chemical deposition, dust or dirt that will affect transformer’s insulation seriously, also explosive or corrosive medium is not allowed.
5.If any special working conditions that are not in line with the above stipulations, user shall negotiate with us.

Main technical characters 

  The primary and secondary windings are winded separately, when the secondary one only has one winding, then it takes on all the rated capacity for transformer. If the seco -ndary one accompanied with control, lighting and indicator lamp windings, it will be winded respectively according to each winding capacity. For simplex winding tra -nsformer with center tap, all the center taps capacity should be lower than rated cap -acity of transformer, only the max voltage output terminal can bear the rated capacity.

Notice:

  1.Before purchasing, please calculate out the total capacity of electrical appliances that you are using and then choose right transformer, make sure that the transformer will not be burnt during instantaneous starting.
  2.This transformer is designed and produced according to national relative standards strictly. When you apply transformers with multi windings ( multi control voltage), please accord to the voltage ratio to add transformer’s capacity proportionally, so that the transformer will not be burnt.
  3.Before installing please check the data that on the nameplate carefully to see if the specification is what you need, only after confirmed that you can install and put it into use.
  4.After switching on, the iron core and coil of transformer will be heated ( but the temperature rise will not exceed 80°C), it’s a normal phenomenon, once the temperature rise exceeds 80°C, even there is smoke, please cut the power supply and check the capacity of electrical appliances again.
  5.During transportation, try to avoid impact, and far away from damp. During operation, pay attention to maintaining to ensure the transformer’s service life.
