The SNE network engine is powered with either a 24 VAC power transformer or a portable power adapter that supplies 24 VDC. In North America, use a Class 2, 24 VAC power supply with a 50 VA minimum output. Outside North America, use a 24 VAC SELV transformer at the appropriate rating. The minimum input voltage for the network engine to operate correctly is 20 VAC.
Use a dedicated power supply to the network engine only. Do not connect any other loads to the power supply. Additional loads may cause noise interference.
