The SWI4532DT is part of the new 5 input compact multiswitch range designed to fulfil every installation requirement in small and medium sized distribution systems. Outputs on both sides. Each output powers its own port therefore reducing the total consumption of the external power supply. The switch is powered by an external power supply 1600mA @ 12V with an RCA connector. It has an internal circuit for automatic detection and powering of a masthead amplifier. The masthead amplifier is powered by the PSU.
