Feature: 1. Continuously Regulated and LCD: The power supply is a regulated DC power supply with continuously adjustable current and voltage, with a large LCD display with backlight for accurate reading of voltage and current values. 2. Cooling Fan: When heat builds up inside the case, the intelligent thermal protection will activate the cooling fan to reduce the temperature when the operating temperature is higher than 122℉ or 50℃. This regulated DC power supply can be used in electronic circuits such as operational amplifiers and digital logic circuits. 3. Accurate Encoder Knob Setting Values: This regulated DC power supply requires only voltage and current settings. You can press the voltage and current encoder knobs to select the number to be adjusted and then turn the knob to set the value from 0 to 9. 4. Efficient and Energy Saving: The encoder switch of this regulated DC power supply replaces the potentiometer switch, making your work easier, more accurate and efficient, efficient, compact, energy saving. 5. Multiple Protection: The DC power supply is reliable and safe with excellent electronic components and many safety measures, leakage protection, thermal protection, overload protection and short circuit protection.
