Solid State Relay SSR-50DA 3-32VDC 50A/250V Output 24-380VAC With Cover
A part of the review has been auto-translated.
The internals of this item are a BTA24-800, which is only rated up to 25A. Probably requires better cooling if you use it at that current. Still much better than the SSR-25 which are usually rated at 12A. Separation between the low and high voltage side is moderate. This is alright in combination with an arduino or other microcontroller, but I would not recommend for use with expensive control circuitry. I put a small relay between my circuit and this item for maximum isolation (Circuit -> Relay connected to isolation supply -> low voltage side of SSR) .
Симисторное реле (только для переменного тока). Разумеется нужен радиатор для большого тока. В работе не проверял, но выглядит все хорошо. Начинка залита силиконом, но не полностью.
