Product Description

Micro Compact Variable DC Power Supply 30V 60V 150W/300W Switching Regulated Source

Overview

The ultra-mini DC regulated power supply is a tiny single-channel DC power supply with a four-digit digital tube that simultaneously displays voltage, current and power values. It is equipped with an "ON/OFF" output switch and a USB fast-charging output. Lightweight and compact, it is the ideal preferred test tool for customers.

Features
Small in size, fully functional
Independent ON/OFF output switch
It can remember the preset voltage and current values before turning off
External USB Type-A fast charging
Key lock function to prevent misoperation

Applications

Teaching & Laboratory (Classroom demonstrations, student experiments, tech innovation projects)

Desktop R&D (Embedded systems development, module testing, prototyping & debugging)
Mobile Repair (On-site repair for cell phones, laptops, home appliances, etc.)
Field Debugging (On-site equipment maintenance, exhibition demonstrations, outdoor testing)

Panel Introduction

1 .Voltage display window: Shows preset voltage values in standby mode; In the output state, display the output voltage value. Unit:
volts (V).
2 .Current display window: Displays preset current values in
standby mode; Display the output current value in the output state. Unit: Amperes (A).
3 .Power display window: In standby mode, shows "OFF"; In the output state, show the power output of the power supply. Unit: Watt (W).
4 .18W fast charging output port: QC18W (5V-3A/9V-2A/12V-1.5A).
5 .Output on/off button : Short press to switch output status.
6 .Positive(Red) output terminal.
7 .Negative(Black) output terminal.
8 .Keypad Lock indicator : Hold down the current knob lock
indicator light. The lock indicator light is yellow, indicating that the knob is locked; Hold down the current adjustment knob again and the lock indicator light will turn off and the lock will be released.
9 .Current adjustment knob: Rotate clockwise and the preset
current value increases. Turn it counterclockwise and the current preset will decrease. Press the knob short to move the current
preset editing position from right to left; Hold down the knob to lock/unlock the knob.
10 .CC Constant current indicator : The red "CC" light on, indicating that the power supply is currently in constant current output mode.
11 .Voltage adjustment knob: Turn clockwise to increase the preset voltage value; Turn it counter clockwise and the preset voltage will decrease. Press the knob short to move the voltage preset editing
position from right to left; Long press the knob to save the current output state, and the next time the power is connected, restore the previous output state directly.
12 .CV Constant voltage indicator: The green "CV" light on,
indicating that the power supply is in constant voltage output mode at this time.
