WebThe electromechanical relay is the sole option in applications where a circuit must be entirely on or off with little on-state voltage drop and no risk of harm or damage from leakage current. If high surge currents or spike voltages are expected or known to occur, EMRs are also the best option. WebMay 19, 2024 · When I later needed to route either AC or DC to the motor for electronic braking, that AC-or-DC switching had to be done by a mechanical relay. I couldn't use a solid state circuit using my existing SSR, partly because the leakage current of the SSR wouldn't truly cut off the AC supply, mostly because an SSR failure to always-on would put AC ...

WebCurrent leakage on a Solid State Relay. I built a system to control an 240v AC device (specifically a pool pump) using a Solid State Relay, controlled with a Raspberry Pi. I noticed there is some current leakage, as when the relay is open, an LED desk lamp connected to it will strobe. My pool pump doesn't start and stop, it just stays off.
