Feature

●【Description】This circuit is a high-quality, continuously adjustable regulated power supply with a voltage regulation range of 0-30V. It also includes a current output limiting circuit to effectively control the maximum output current from 2mA to 3A continuously
●【Advantage】Although the switching power supply with high efficiency, small size advantages, but inevitably residual high-frequency interference, and linear power supply because of its very low interference and good isolation
●【Features】The power supply board kit are all in-line components, installation, maintenance simple and convenient. It is the first choice for enthusiasts and even professional manufacturers for doing a variety of circuit experiments
●【Safety】The regulated power supply board can limit the current in the experimental circuit of the typical maximum operating current, boldly turn on the power, do not worry about failure or installation errors caused by high current damage to the experimental circuit
●【Convenience】The output voltage is easy to adjust. The output current limit state is indicated by an LED. When the output current exceeds the limit current automatically switches to constant current mode, the overload or failure to provide complete protection

Note:
1. The radiator and fan are not included in the kit. You can bring it yourself or buy it in the store. There is an external 24V cooling fan connector on the board. The adjustment tube of this circuit must be added with a sufficiently large radiator or fan to operate with load, remember! Otherwise, the adjustment tube may be damaged due to overheating.
2. The potentiometer can be directly soldered to the board, or it can be led to the panel installation. The kit is equipped with connecting sockets and connecting wires.
3. The power transformer uses 24V AC output (or dual 12V, the center tap is empty, not higher than this voltage), the power can be selected according to need, if you need 30V 3A output, the transformer power needs to be greater than 90W.
4. The power supply is a high voltage and high current circuit, please be careful, otherwise it may cause harm to physical safety! This shop only guarantees the correctness of the kit and circuit, and does not bear any adverse consequences caused by the production
