Shihlin Electric FAQ: Selection, Wiring & Troubleshooting

Why need to use models with bigger capacity in higher altitude area?

Air density will be reduced in areas beyond 1000m altitude, making it easy for temperature rise but hard for dissipation. Rated capacity will be reduced by 5% when increasing altitude by 1000m. So choosing higher capacity in higher altitude is suggested.
