Buying Guide & Selection Tips
When selecting an industrial control transformer, consider the following factors:
- Determine Required Capacity – Choose a transformer with at least 125% of your equipment’s rated power to avoid overload.
- Match Input & Output Voltage – Confirm compatibility with your power supply and load requirements.
- Check Insulation & Safety Ratings – Ensure the transformer meets IEC, CE, RoHS, and ISO standards.
- Consider Installation Environment – For high-humidity or high-temperature locations, select higher insulation classes.
- Request Custom Solutions – If you need a specific voltage combination or compact design, we provide OEM & ODM customization.
Q1. What is the difference between a control transformer and a power transformer?
A control transformer is optimized to provide stable, low-voltage power for control circuits, while a power transformer handles large-scale energy transmission. Control transformers are designed for precision and reliability in automation and industrial applications.
Q2. How do I choose the right capacity for my industrial transformer?
Add up the total power rating (VA or kVA) of your connected equipment and select a transformer with 25–30% higher capacity than your calculated load to ensure safe operation and avoid overheating.
Q3. Can this control transformer be customized?
Yes. We offer custom input/output voltages, special mounting designs, and multi-tap configurations to meet your exact project requirements.
