Frequently Asked Questions
Q: What input voltage does this switching power supply module require?
A: This module is designed for a standard AC 220V mains input, making it suitable for use in Europe, Asia, and other regions where 220V is the standard mains voltage. It is not suitable for direct use with 110V mains without a step-up transformer.
Q: Can I adjust both the voltage and current output on this power supply module?
A: Yes. This module supports both Constant Voltage (CV) mode, where you set a fixed output voltage between 0V and 30V, and Constant Current (CC) mode, where you set a maximum current limit. Both are adjustable via front-panel controls, making it versatile for battery charging, LED driving, microcontroller testing, and more.
Q: Is this power supply module suitable for continuous use in a lab or workshop?
A: Absolutely. The module is designed for long-term, continuous operation, delivering a stable 350W output. It is well-suited for electronics labs, product development benches, repair stations, and educational environments where sustained, reliable power is essential.
Q: What kinds of electronic devices or projects can I power with this module?
A: The wide 0–30V adjustable output makes this module compatible with a broad range of applications, including microcontroller development boards (Arduino, ESP32, etc.), LED strips, DC motors, radio equipment, sensors, and custom DIY electronics projects. The built-in current-limiting feature also makes it safe for powering more sensitive or current-critical loads.
