Help on identifying Science Fiction TV series from the 80's

I might be way off here but i have a question that has been bugging me for the last couple of weeks and i hope that someone out there can help me

In the late 80's I watched a Science Fiction TV series running on Super Channel (via satellite from UK to Denmark). I can't remember what it was called only that it was about 4 or 5 heroes fighting the evil. They had some kind of suite they could turn on by pressing a bottom and saying "POWER ON". If someone know what that series is called or is better at Googleling then I would really like the here from you.

Thanks for any help

Hey dibujack
If it way animated it sounds like The Centurions, look it up in IMDB o YouTube.
Anyway, I also need to identify a Science Fiction TV series, maybe from the late 80s. It was about an undercover cop who meets a woman who (I think) turns out to be extraterrestrial. As the story unfolds he finds out about and impending invasion. And I think there was some predator-like alien chasing them both. All I can remember is very fuzzy.
I hope somebody can tell me that series name 'cause it's killing me.
