This 12V solar charge regulator meets most small-scale application requirements ... The switching is accomplished via an inexpensive 10A relay. One of the interesting features is the secondary load ...

In 12-volt automotive circuits, even small resistance amounts can cause significant voltage drop. Relays provide a solution by shortening the required length of the heavy-gauge, power-delivery ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

These G9TA relays feature 2mΩ contact resistance, 6kV impulse withstand voltage, 250Vac max switching voltage, and 12Vdc coil voltage. The 120A (276Vac, or 100A with PF=0.5 inductive load) G9TB AC ...
