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.

Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power ...

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 ...

Automotive electronic control applications require robust input power conditioning. The circuitry must absorb 100-V transients on one hand, while providing a stable dc bus for a few hundred ...
