Solid State Relays (SSR)
A solid state relay (SSR) is a digital switch for AC current. With a small DC voltage, it can switch high AC currents.
When using SSRs to switch high currents (for heating elements), they do require a heat sink. For switching a small fridge or 60W heater, the current is so low that a heat sink is usually not necessary.
Compared to mechanical relays, SSRs have a few benefits:
- They switch on an AC zero crossing, resulting in much smaller inrush currents
- They do not have a limited number of switching cycles, so they are suitable for switching often (as done with PWM).
- They are silent
