The Application:
This single phase isolation transformers and single phase auto transformers are widely applied to three phase power supply of import-export equipment, safeisolation power supply, step up-down power supply, rectifier equipment power supply, detecting system, power supply,UPS power supply,CNC machine and kinds of machinery power supply.

Feature:
1)  Ventilated openings in the enclosure are coordinated with the cooling ducts in the coils to ensure proper natural circulation of air for long life and minimum losses.
2)  General purpose indoor ventilated steel enclosure suitable for dry locations. After fabrication, the enclosure is finished in ASA61 grey powder paint suitable for most industrial and commercial installations.
3) Most units have lifting lugs, conduit knockouts and removable front and back covers for easy access to terminals.

Operating environment
1)Temp.:The ambient temperature can not over +40℃。
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

Certificate
The certificate of our transformer has CE CQC RoHs UL

Note:
The above-mentioned single phase isolation and auto transformer are 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.
