ALIENTEK DP100 – compact DC power supply, 30 V / 5 A / 100 W
Precise power for electronics projects – even when you're on the go! The ALIENTEK DP100 is a compact, digitally controlled DC power supply for prototyping, troubleshooting, and circuit testing.
You can set the output voltage from 0 to 30 V and the current limit from 0 to 5 A. The power supply operates in constant voltage (CV) or constant current (CC) mode, and the small IPS display shows voltage, current, power, and operating status. Buttons and a control knob make it easy to adjust the settings.
Save up to 10 sets of settings for tasks you repeat. USB-A is used for PC communication and firmware updates and also supports operation with a compatible USB mouse.
The DP100 is a step-down power supply: The input voltage must be higher than the desired output voltage. It requires an external power source via USB-C, such as a compatible PD/QC charger or power bank. The available output power depends on the power source and cable.
The maximum output power is 100 W. 30 V and 5 A cannot therefore be delivered simultaneously. Protection features include overvoltage, overcurrent, overpower, overtemperature, reverse connection, and undervoltage. Always check the voltage, current limit, and polarity before connecting.
