Select parallel code, Delta will parallel the outputs before shipping to customer. Parallel feature is designed for singe slot modules and only two modules can be paralleled. Triple slot modules and dual output module cannot support this option. Please notes that trimming the parallelled output voltage through potentiometer is forbidden on customer side. If customer needs to adjust output voltage after paralleling modules, please consult Delta for support. Table 2 Parallel Code Code 1 2 3 4 5 6
