1) A relay that open the connection to the load That sounds like the simplest to me: Use a relay with a 24V AC coil, connected to the transformer output (before the recfifier). Then as soon as the mains goes off, the 24V AC goes off, and the relay disconnects the DC out. You could have a little light connected across the capacitors - that would warn that they still have charge even though the load is off, and would also gently discharge the capacitors! |
