AT30 Automatic DC Converter – Adjustable 0.5-30V Power Supply for Lab and DIY Projects

Compact Module with Wide Input Range and Precision Output Voltage Regulation

The AT30 module is an automatic DC-DC buck-boost converter that eliminates the need for manual switching between modes. It automatically adapts and maintains a stable output voltage (from 0.5V to 30V), regardless of whether the input voltage (4-30V) is higher, lower, or equal to the desired output. With high power (up to 4A / 60W), protections (short circuit, overload, reverse polarity), and efficiency up to 95%, this module is a universal solution for powering projects with variable sources such as batteries, solar panels, or automotive systems. It is ideal for powering 3D printers, chargers, LED strips, or for DIY laboratory power supplies.

Product parameters:
Input voltage: 4-30V
Output voltage: 0.5-30V
Output current: 3A, 4A with cooling fan
Output power: 30W without cooling fan,60W with cooling fan
Output ripple: 30MV (Full output voltage)
Conversion efficiency: Boost, 88%-91%; Buck,87%-90%.
Short circuit protection: Yes
Working frequency: 180KHz
Size: 48*23*21mm
Features:
No matter how large is the input voltage, the output voltage can be fixed on 12V.
when input voltage is 12V, the output voltage can be bucked to 5V, or boosted to 24V.
It is more efficient, more power than the XL6009-type module.
The ultra-low output voltage ripple
the output voltage ripple is only 20 mV when the input voltage is 12V, current is 3A, especially for the audio / power amplifier board, analog circuit power supply!
With a mobile phone charger or battery-powered, you can achieve 0.5 to 30 volts adjustable DC power supply, very convenient!
