Buying Guides
Generally speaking, a transformer can be chosen on the basis of just a few elements. Once this info has been established, any other optional requests can be considered separately.
Power Rating: You can provide either load capacity in KW or the voltage transformer power in KVA.
Input & Output Voltage: Input voltage is the mains supply voltage, and output voltage is the voltage that load needs.
Winding Material: Both Al and Cu are available for choice, the default material is Aluminum.
Insulation Class: Both F and H insulation class are available for choice, the default insulation level is F.
Vector Group: Please specify vector group (Dyn11, Yyn0, etc), Delta or Wye (star) connection.
Tapping Range: ±2.5%, ±5%, etc.
IP Rating: IP00, IP20, IP21 for indoor use, IP44 and above for outdoor use.
Installation Conditions: In order to provide with the most suitable indoor and outdoor transformer, it is recommended to provide with the installation conditions. It is necessary to know: IP protection degree; Indoor or outdoor installation; Installation site altitude and climatic characteristics; Ambient temperature.
Applications
A small size isolation transformer is used for isolation in pulse circuits.
An isolation transformer with a ratio of 1:1 is used under load conditions (as a power transformer) for safety purposes.
Electrical isolation is necessary for medical equipment and some special standard equipment. In that case, an isolation transformer is connected with equipment.
An isolation transformer is used to reduce harmonics and transient in electrical circuits.
It is also used to provide electrical isolation between the power source and equipment.
It is also used to safely troubleshoot and test electrical and electronics components without touching the live part of the circuit which protects from the electric shock and hazardous voltage.
