Feature: 1. STRONG COMPATIBILITY: USB fast charging 18W, new upgrade supports multiple fast charging protocols, fast and convenient. 2. ENCODER ADJUSTMENT: Press the knob to move the adjustment position, adjust the value, and preset the voltage and current. 3. OCP SHORT CIRCUIT ALARM SWITCH: When this function is activated, when the load device experiences a short circuit, the power supply will stop output and a beep will sound to prompt. After the external short circuit is relieved, the power supply will automatically resume output. 4. HIGH ACCURACY DISPLAY: Bench power supply has a LED four digit display of voltage, current, and power, with accurate digital display. 5. LOW RIPPLE AND LOW NOISE: Low voltage fluctuation, low noise, stable output, and low interference effectively contribute to work requirements. 6. FULL LOAD STABILITY: DC power supply can be used at full load without burning the machine, providing convenience for your work. When the internal temperature of the power supply reaches a certain level, the fan automatically turns on for heat dissipation. 7. SMALL AND PORTABLE: Exquisite and compact, easy to control with one hand, small in size and light in weight, saving more space for the workbench.
