Hi i try to find on internet for a latching relay for 100A and 100V DC resistive loads, all the ones i found are at 28V dc max
If you found something even if it is from china i would be very interested
thanx i had found those but they are over 300$ each!!!
Big Amps cost Big Bucks!
What is your coil voltage?
Here is a 12v Power Relay for $6.50 **broken link removed**
12 VDC POWER SOLENOID | AllElectronics.com
if i do a switch with about 10 mosfet in parallel, could it work? will the current be share (i will take all similar mosfet with same rds)
can i put them back to back to make a swtich with no polarity?
if it is possible even with 20 mosfet it would be still be less expensive than a mechanical relay (minimum 200$ for a good one!)
SCRs will work anSCR will latch with DC and they are cheep.
