Tecpro PS711 3-Channel Intercom Power Supply

The PS711 is a power supply which serves as the system master in small, simple systems. Three separate communications circuits are provided. These can be linked by silent acting front panel switches in any combination. Up to 16 headset outstations, or a mix of headset and loudspeaker stations can be operated. The PS711 is rated to support these even in the event that the signal lamps on the system are permanently illuminated. The PS711 is protected against short-circuits, over-temperature and reverse voltages and is designed to survive the rigours of use in temporary installations. The PS711 may be chained into a circuit with any other Tecpro master stations or power supplies to boost the system capacity.
