Figure 1 A series diode protects systems from reverse polarity but wastes power in diode losses. Figure 2 You can use a bridge rectifier so that your system works no matter what the input polarity is.

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

The Jackson Systems TK-400 is a universal twinning/paralleling kit designed to allow a single thermostat to control multiple HVAC units. It was engineered to incorporate solid-state, diode relay logic ...
