About this item

  • 【High-precision encoder knob】Different from general knobs, this DC power supply has a precise encoder knob. You can press the knob to switch each digit, and then turn the knob to customize each digit in the range of 0-9. Set the voltage or current you want more accurately.
  • 【Output Enable/Disable Button】In the process of using the bench power supply, Output button can prevent us from forgetting to turn off the output and causing damage to the load. Just press this button to turn on or turn off the output of the power supply. This makes it more convenient for you to use the power supply.
  • 【Overcurrent Protection】When the OCP function is turned on, if the load equipment is short-circuited during operation, the adjustable power supply will automatically stop output and send a buzzer to alert the user. Protect the adjustable power supply and load from damage.
  • 【Precise 4-digit LED Display】The variable power supply with a high-definition 4-digit display, which can display three values of voltage, current and power at the same time. The data is accurate to 0.01V and 0.001A. The bright white digital display helps you to operate as usual in the dark, and you can adjust the brightness of the screen as needed.
  • 【Compact and Lightweight】The measures of the variable dc power supply is only 7.51*3.56*5.81inch and the weight is only 2.47 pounds, which saves more space on your workbench and is convenient for you to carry when you need it. NANKADF dc power supply is the best choice for beginners or professional electricians.

Product Description

dc power supply
bench power supply

dc power supply

NANKADF dc power supply has a humanized design, compact and lightweight appearance. It uses high-quality built-in circuit board and a sturdy, anti-drop shell. Accurate encoder adjustment meets the high requirements of professional electricians. Multi-layer safety protection, simple and convenient operation, it is also the best choice for beginners and amateurs.

Technical Parameters:

1:Output voltage:0-30V adjustable

2:Output current:0~10A adjustable

3:Output power : voltage (V) * current (A)

4:Auxiliary functions:Output button, OCP short-circuit protection, USB fast charging interface

5:Input voltage:AC 115V ± 10%; AC 230V ± 10% (switchable option)

6:Protection mode:over-voltage protection, over-current protection, over-temperature protection, short-circuit protection

HD large screen display

Has buttons that can control the output on and off

AC 110V/220V input changeover switch

High precision stable output

This lab power supply can display voltage, current, power and other parameters at the same time. And you can observe its constant voltage (CV) cross-current (CC) as well as short-circuit protection (OCP) and output on/off (OutPut) indicator changes from the screen to know its working status!

When you press it, the OUT status light will be displayed in the lower left corner of the screen (the power supply is in the output state at this time), and pressing the OUTPUT button again will cut off the output.

In addition: When you press and hold the OUTPUT button for 5 seconds, you will find that the power supply will enter the setup screen with six mode settings. You can download our product manual to view these settings.

You need to check this switch if you need to access 110V (leave it at 115V). Please note: If the switch is in 230V state, the power supply will not reach the maximum power when you let you use 110V.

If your input voltage is 220V, then you need to adjust it to 230V state. Please note: If you use a voltage of 220V, the transfer switch of the power supply is 115V, the power supply may be damaged when energized.

the power supply output is stable and precise, with multiple protection (overvoltage protection, current limit protection, short circuit protection, overheating protection, etc.) to effectively extend the product life.

Multifunctional encoder adjustment knob

Encoder adjustment knob

used to adjust the voltage/current, turn clockwise to increase the value; turn counterclockwise to decrease the value. Press the encoder knob to move to the left. After the setting operation is completed for 3 seconds, the flashing stops and the current setting is saved
