DC Power Supply (0 120V, 0 3A) Adjustable, Switching Power Supply

  
High Precision and Small Size : The power supply adopts 4 - digit LED display, voltage display 0. Voltage, current, power three windows display (0 - 120V / 0 - 3A adjustable). 47 pounds, the size 7. 9 inches is easy to carry. Digital Adjustment : This power supply is encoder adjustment, it can be pre - set to the parameters you need and through the OUTPUT button to turn on or off the output of the power supply (when you trigger the OCP protection can press the OUTPUT button to lift the protection state). USB Fast Charging Interface : the power supply is configured with 18W fast charging interface, supporting a variety of fast charging protocols. Automatically adapted to the fast charging protocol of the device being charged. The USB can save your workbench space and power your electronics. CC / CV Automatic Switching : constant voltage and constant current values can be preset by coding knob, and automatically switch CC / CV state according to the load state. The product has OVP, OCP, SCP, temperature - controlled heat dissipation and other perfect protection mechanisms to effectively extend the service life of the product.

OCP Short Circuit Protection Function : press the CURRENT code switch for 3 seconds (can turn on or off the short circuit protection alarm function). Ocp enabled, when the external load short circuit or overcurrent power supply will stop output and sound an alarm (can effectively protect the tested products) you can get (power supply x 1, British standard AC power supply x 1, output crocodile clip load cable x 1, product User' s Manual x1). Series laboratory switching power supply is a full - featured, simple and beautiful design of easy to operate power supply.

The small body is made of high - quality components, the power supply itself has short - circuit protection, over - voltage protection, over - current protection, over - temperature protection and other perfect protection mechanisms, ideal for the majority of electronic enthusiasts and beginners to use. Voltage, current, power three - line LED high - definition display. The display has a protective film (you need to check it yourself because of the tight fit with the screen).

Unlike the analog regulation of ordinary DC power supply, this power supply is regulated by encoder. It will make it easier and faster for you to set the power supply parameters. Power supply size and weight.

The size of the product is only : 5. The small size and mass of this power supply will not take up too much space on your workbench.

Output on / off switch. The power supply is configured with an output on / off switch. The setting of this button turns the output of the power supply on or off. And in case of short - circuit alarm, pressing can release the alarm and enter the off output state. This model supports an independent USB fast charging port with a built - in fast charging protocol chip and a maximum output power of up to 18W to provide fast charging for cell phones, PADs, charging pads and other devices with fast charging protocol. The output power is automatically adjusted according to the fast charging protocol supported by the device being charged, and will be output at standard 5V when used by devices that do not have fast charging capabilities. This power supply can accurately set the voltage and current you need, and it can automatically calculate the output power based on the output voltage and current, while displaying the voltage, current, and calculated power on the screen. 110V / 220V transfer switch. Different from the power supply with ordinary single voltage input type. This power supply has 110V / 220V dual voltage input, which allows you to use in different country locations.

Just note before use : in 110V voltage environment, you need to adjust the toggle switch to 115V. In 220V environment, you need to adjust the toggle switch to 230V.
