AC-DC source module kit, continuously adjustable, 0-30V, 2mA-3A, unassembled

Unassembled kit for an adjustable AC to DC power supply that offers the ability to adjust the output voltage from 0V to 30V and the output current from 2mA to 3A. The components are of the TH (Through Hole) type, which means that it is easy to assemble, without the need for SMD soldering equipment.

ATTENTION: The module uses AC voltage for power. You need a 24VAC transformer to use the kit. Considering the fact that it uses mains voltage, this kit is NOT INTENDED FOR CHILDREN ! It can be used as soldering practice.

Many components of the kit ARE SIMILAR in appearance and size BUT THEY ARE DIFFERENT in values! Always check the inscriptions on the components before mounting them. All the components and their orientation are marked on the PCB. The kit does not come with instructions other than those written on the PCB. This product benefits from a warranty on components strictly until the moment of assembling the components.

It has over-current and short-circuit protection functions, ensuring the safety of connected devices, preventing any risk of burning or damage.

Use:

Follow the markings on the PCB to correctly assemble the kit. It is recommended to have basic knowledge in electronics and to use a quality letcon.

Power the kit with 24V AC , using a suitable transformer, respecting the maximum current limit of 3A.

Adjust the potentiometers to set the desired output voltage from 0V to 30V and current from 2mA to 3A, depending on your preferences.

The LED indicator will light up to signal the overcurrent protection, activating in case of an overload or a short circuit, thus protecting the connected devices.

Used with a 2-wire transformer, the Phase and Neutral are connected to the first and last pin respectively of the input connector. On the AC input in this case, the middle pin (0V) remains free.
