Powering Additional Equipment

A lot of additional equipment need power to be able to operate as intended. The source of such power varies depending on the type of exchange.

AlphaCom E7

E7: +24VDC Output

If the additional equipment is located in close proximity to an AlphaCom E7 Exchange, the exchange can provide 24VDC from a dedicated output. If other kind of power is required, or if the additional equipment is mounted away from the exchange, a suiteable local power supply is needed.

AlphaCom E20

E20 Power outputs

The AlphaCom E20 Exchange has an ouput which allows for connection of +5VDC, +15VDC and +24VDC. All the outputs are protected by their own dedicated fuse. Additional equipment that requires an external power source may use these outputs.

AlphaCom E26

E26 with mandatory PDB

When using additional equipment with an AlphaCom E26 Exchange, the Power Distribution Board, PDB, is recommended. The PDB board can provide +5VDC, +15VDC, +24VDC and +32VDC from a number of outputs with several different connection types. The PDB board also contains a fuse for each voltage.
