DPH doorphone supply can be realized using AC or DC. Power supply device should be selected according user needs. Due to wide possibilities, Slican company doesn't offerany power supply device together with DPH doorphone, it remain to user decision. In Slican offer - as a separate position in price list - there is AC transformer TRS10-V18-N, with nominal voltage equal to 18V, this transformer fulfil supply requirements of DPH doorphone. Below is presented mentioned above transformer:
