Product type
Voltage transformers are electrical devices used to reduce high voltages to lower levels for measurement and control purposes. They operate on the principle of electromagnetic induction, converting the primary voltage into a proportional secondary voltage that can be safely measured and utilized. Typically constructed from high-quality insulating materials and precision windings, these transformers ensure reliable performance in various applications.
| Voltage Ratio | Typically 1:10 to 1:1000 |
| Frequency | 50 Hz to 60 Hz |
| Insulation Class | Class A to Class F |
| Accuracy Class | 0.1 to 0.5 |
| Temperature Range | -20°C to +40°C |
When selecting a voltage transformer, consider the voltage ratio that matches your measurement needs and the accuracy class required for your application. It's also important to specify the insulation class based on the environmental conditions where the transformer will be installed. Additional factors such as frequency, temperature range, and required certifications should be clarified when requesting a quote. Quantities may vary based on project size, so be prepared to discuss your specific requirements.
