Power supply box components and inner circuits can be found at various online retailers, including the following sources: https://www.aliexpress.com/item/DC-CC-9A-300W-Step-Down-Buck-Converter-5-40V-To-1-2-35V-Power-module/32448126827.html This module is a DC-to-DC converter that can step down voltages from 5 to 40 volts to a range of 1.2 to 3.5 volts, making it suitable for powering various electronic devices. Another component found in the power supply box is a voltmeter and ammeter combo, which allows users to measure both voltage and current readings with high precision. The device features blue and red LED displays that provide clear visual feedback. For AC-to-DC conversion, the power supply box may include an AC converter module capable of handling 110V or 220V input voltages and producing a stable DC output up to 36 volts with a maximum current of 6.5 amps. This makes it suitable for powering devices that require a constant DC voltage. Additionally, the power supply box may contain precision potentiometers like the 3590S-2-103L model, which features a 10K ohm resistance and a high-resolution multiturn adjustment mechanism with 10 rings.
