Frequently Asked
Questions!
1. What is the ST Series adjustable power supply?
The ST Series is an adjustable AC-DC power supply designed to provide flexible DC output for testing, repair, R&D workbenches, battery testing and industrial equipment applications. It allows users to adjust the output voltage and current according to different project requirements.
2. What output ranges are available for the ST Series?
The ST Series supports multiple adjustable output ranges, including 0–15V, 0–30V, 0–60V and 0–110V. The suitable output range depends on your equipment, testing object, load type and required current.
3. What power ratings are available?
QuntroTech supplies ST Series adjustable AC-DC power supplies in 1000W and 1500W models. These models are suitable for applications that need higher output power and flexible voltage/current adjustment.
4. Where can ST Series adjustable power supplies be used?
ST Series power supplies are commonly used for industrial testing, equipment repair, laboratory workbenches, R&D projects, battery testing, motor testing, electronic product development and equipment debugging.
5. How do I choose the right ST Series model?
To choose the right model, you should confirm the required voltage range, current demand, power rating, input voltage, load type, working environment and continuous operating time. If your application may change in the future, choosing an adjustable power supply can provide more flexibility than a fixed-voltage model.
6. What is the difference between an adjustable power supply and a fixed-voltage power supply?
A fixed-voltage power supply provides one specific output voltage, such as 24V or 48V. An adjustable power supply allows the output voltage and current to be adjusted within a defined range, making it more suitable for testing, repair, R&D and applications where requirements may change.
7. Can the ST Series be used for battery testing?
Yes. ST Series adjustable AC-DC power supplies can be used for some battery testing and power simulation applications, depending on the voltage range, current demand and testing method. For battery charging applications, it is better to confirm the battery type, charging profile and protection requirements before selection.
8. Can the voltage and current be adjusted externally?
Some ST Series models support external voltage and current adjustment depending on the model design and project requirements. Please share your required control method, voltage range and application details so QuntroTech can help confirm the suitable option.
9. Are you a manufacturer or trading company?
