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.
