Technology FAQ for Buyers

Short answers for common purchasing questions.

Is spark gap always better?

No. It is better for certain high-energy entrance roles, not automatically better at every sub-board.

Is MOV too weak for lightning regions?

Properly staged systems using Type 1 at the entrance and Type 2 downstream are proven in high keraunic regions.

Should I mix brands casually?

Prefer coordinated stages from known data. If mixing, engineer the energy coordination explicitly.
