For each of the output poles there are 3 terminals allowing the connection of multiple loads. High performance / cost ratio. FPFE: Switching power supply with compact dimensions, the smallest on the market for 120W, only 32mm in the FPFE10324 and FPFE10524 models and only 44mm in the FPFE11024 model. Available with an output voltage of 24 Vdc, adjustable from 24 to 28V. Visual indication and output relay for DC OK. Integrated Active PFC> 0.95 (Adjusted Power Factor). Between 91% and 94% maximum efficiency and without loss of power when working in the temperature range from -25oC to + 55oC and gives 70% power up to 70oC. "Power Boost" up to 150% of output power for 3 seconds. A switch on the front face that allows the selection between working as an isolated source or in parallel. Parallel work also serves as redundant.
