Toroidal transformer

NAME:Toroidal transformer

• Product Description
   
• Toroidal transformers are built around a ring-shaped core,which,depending on operating frequency,is made from a long strip of silicon steel or permalloy wound into a coil,powdered iron,or ferrite. Toroidal transformers are more efficient than the cheaper laminated E-I types for a similar power level. Other advantages compared to E-I types,include smaller size (about half),lower weight (about half),less mechanical hum (making them superior in audio amplifiers),lower exterior magnetic field (about one tenth),low off-load losses (making them more efficient in standby circuits),single-bolt mounting,and greater choice of shapes.
• Application:
  This kind of toroidal transformer is widely used in electronic equipment and other electronic equipment of higher technical requirements,such as computer,medical equipment,telecommunications and lighting and so on.
   
• Material
  Core: High quality cold grain silicon sheets inserted by machine,annealed by advanced vacuum annealing furnaces to improve electronic data
  Bobbin: Excellent Anti-combustion
  Wire Materials:
  1. Copper,Aluminum,Aluminum Clad Copper.
  2. The size of transformer total in Aluminum is larger than which total in Copper.
  3. Aluminum instead of Copper Cost Save: 13%-35%/PCg
   
• Advantages of toroidal transformers
  Efficiency
  Smaller in size
  Lower in weight
  Less mechanical hum
  Low exterior magnetic field
  Low off load losses
  Single mounting point
   
• Operating environment
  1)Temp.: The ambient temperature can not over +40degree Celsius
  2)Altitude: Mounting location can not exceed the altitude of 2000m
  3)Relative humidity: Maximum 90%
  4)The site not attack by rain and snow
  5)The medium which no explosion danger,no corroding metal,no electrical breakdown
   
• Testing Items:
  No-load Test(No-load Current,No-load Voltage,No-load Loss)
  Load Test (Load Voltage,Temperature-rise)
  Inductive Voltage Test
  DC Resistance Test
  Safety Test
   
• Warning
  Under no circumstances should both ends of the fixing bolt simultaneously contact the metal chassis or framework as this would create a potentially dangerous “shorted-turn”.
   
• Certificate
  The certificate of our transformer has CE CQC RoHS UL
   
• Note
  The above-mentioned toroidal transformer is frequently-used,we can also manufacture the products by customer design. And the specification is for reference,if has the change further,please take the material object as the standard.
