1、ACCURATE ENCODER ADJUSTMENT KNOB: DC power 0‑ 0‑10A unlike traditional adjustment knobs, encoder knobs for DC power supplies allow you to set voltage or current more accurately. You can simply press the knob to switch numbers and turn the knob to set the value you want in the 0‑9 range. With storage memory function, 3 groups of memory, portable storage, 18W USB and Type C fast charge 2、4 DIGIT LED DISPLAY: Laboratory DC desktop power supply is a professional laboratory power regulation device. The backlit 4 bit LED display provide a more accurate reading of voltage and current values that are clearly visible even in low light conditions 3、MULTIPLE PROTECTING: When a short circuit occurs, the variable DC power supply will stop output and issue an alarm reminder. After the OCP function is turned on, when the load device is short circuited(overcurrent) when the function is turned on, the machine will stop output and issue a buzzer alarm. Desktop power supply also has over voltage, over current, over temperature, overload and other safety protecting functions 4、INTELLIGENT AND FLEXIBLE CONTROL: Stable voltage, steady current automatic switching, with output control switch, more flexible control. A/V adjustment switch, one key press switch to adjust the current and voltage, simple and easy to operate 5、VARIOUS APPLICATIONS: DC power supply is suitable for laboratory, school, maintenance, electrolysis, electroplating, brush plating, lamp test, aging test, battery charging, home and other needs Item Type: DC Power Supply Output Current: 0-10A Output Power: 300W Auxiliary Output: USB A or Type C fast charge, support multiple fast charging protocols Operating Temperature: 0℃~40℃, Relative Humidity: <80%RH Storage Temperature: -10℃~70℃, Relative Humidity: <70%RH Protecting: Current limit protecting, short circuit alarm shutdown Constant Current Mode: Current stability ≤0.1%+3mA; Load stability ≤0.2%+3mA; Ripple noise ≤5mArms(effective value) Display Accuracy: 0.5% ± 3 digits Color: Black 1 x Adjustable DC Regulated Switching Power Supply 2 x Output Cables 10 x Other Connection Cables 1 x Power Cord 1 x User Manual
