FS: DC protect using SSR
- Thread starter nigelwright7557
- Start date
It works very well. Sold a few with no problems.
Very low RDSon mosfets.
Cheap camera so cant do much about that.
Mono pcb.
10cm by 10cm
Uses a microcontroller.
Four second power up delay then if any DC for 250mS it shuts off relay.
I have a couple of new mono speaker DC protect pcb's.
These have dc protect and power up/down detect.
About 350WRMS into 4 ohms or 700WRMS into 8 ohms.
No transformer on board so you can choose your own to suit your local mains.
0-9 0-9VAC 5va separate transformer per pcb.
£12-99 each plus p+p.
p+p is £3-99 to uk and £10-99 rest of world.
