The heated components are in direct touch with a big aluminum panel behind the screen. ï&frac*4;ˆ3ï&frac*4;‰Conforming rigorously to EMC A. Fans are exempted from the cooling system, then interference from them is removed; B. The PCB is specially designed to minimize interference; C. The aluminum cabinet is designed such that it shields interference from penetration. ï&frac*4;ˆ4ï&frac*4;‰Thermo-electric shop reduced Soft-starting power supplies are applied, then power is gradually increased or reduced when switched
