Precise Adjustment & Safe Output Control
Features an encoder adjustment knob for precise regulation of voltage and current: press the knob to select the digit you want to adjust, then rotate it to set the desired value. An independent output switch controls the power supply’s output, preventing accidental damage to connected loads. -
Anti-Misoperation & Extra Charging Convenience
Includes a lock button to avoid accidental touches on other buttons during work—this prevents unintended changes to voltage/current settings, avoiding device damage or overload, and keeps your operation smooth. The lab power supply also has a built-in 5V/2A USB port, allowing you to quickly charge mobile phones, tablets, or other devices anytime. -
Safety Protection & Clear Display
Comes with multiple protection functions (current overload protection, overheating protection, overvoltage protection, etc.) to ensure safe and durable use. A color screen clearly shows voltage, current, and power parameters, making it easy to monitor the power supply’s working status at a glance.
