Description
The APWR power supply has four DC outputs delivering the desired voltages for AlphaCom and AlphaCom E exchanges. The power supply is able to supply a STENTOFON AlphaCom exchange equipped with maximum 17 ASLT subscriber cards, which is a fully equipped AlphaCom E20 module. In an AlphaCom E26 exchange, two power supplies are required to supply the complete module; a third can be installed for redundancy.
The power supply is easy to install and connect due to the use of Universal AMP Mate’nLock type output connectors.
WARNING: This 100 9703 000 power supply is incompatible with the older 100 9701 000 supply. Do not put power supplies of different types into the same exchange module.
Mounting
- Remove the upper front cover
