Received on time and well packaged and no hassle. It is a voltage regulator, enters DC up to 30 volts and one can regulate the output through the blue trim-pot that is in the circuit. But it can also be exchanged for a potentiometer of equal value and put on the front panel of some equipment. But it is a very small circuit the aluminum sink is small, in case it heats up a lot it should replace with a larger one and resort to a forced ventilation, but if we work with loads below an ampere and for small times, there should be no problems. The five pieces came individually wrapped. I recommend this circuit.

Recebido a horas e bem embalado e sem problemas. Trata-se de um regulador de tensão, entra DC até 30 volts e pode-se regular a saída através do trim-pot azul que está no circuito. Mas também pode ser trocado por um potenciómetro de valor igual e colocar em painel frontal de algum equipamento. Mas trata-se de um circuito muito pequeno o dissipador de alumínio é pequeno, caso que ele aqueça muito deve-se substituir por um maior e recorrer a uma ventilação forçada, mas se trabalharmos com cargas inferior a um ampere e por pequenos tempos, não deve haver problemas. As cinco peças vieram embaladas individualmente. Recomento este circuito.
