    FAQ

    Q1: Why is the 0ā€“30V model a popular choice for laboratory and development testing?

    0ā€“30V is one of the most commonly used voltage ranges in electronic laboratories, covering most small and medium-powered electronic circuits, power module testing, component characterization, and general bench-top experiments. This adjustable power supply offers precise voltage and current control, making it suitable for research, development, and routine production testing.

    Q2: How does the current rating affect heat management and system stability?

    Higher current ratings generate more heat. The 60A, 100A, 120A and 150A models are designed with enhanced heat dissipation structures. Choosing an appropriately rated current ensures that the power supply operates within a safe temperature range, preventing overheating shutdown and maintaining long-term stability during continuous testing or operation.
