Attached is a pic of a relay in which I'm looking for a sub.
The pickup voltage is rated at 205-234V.
The dropout voltage is rated at 40-105V.
Most everything I'm running into is rated at 35A
and the relay is rated at 50A. I did find a universal
made by ICM Controls, UMSR-50, but don't know if
they are any good.

Any help appreciated, thanks.
