One (1) external power supply bundle for analog card station (FXS) modules
For systems without available internal 12V power connectors, the PWR2400B is the solution. The PWR2400B provides the 12V DC power to analog interface cards that is necessary to drive FXS modules. FXO modules do not provide ring voltage or battery and thus do not require any external power resources. The PWR2400B, which does not connect to the PCI bus, occupies one server slot and provides two 15 12V four-pin cables that can be attached to analog interface cards. The PWR2400B is fed power via one or two Digium external power supplies.
The PWR2400B is intended to be used only with UL Listed Digium analog cards. The PWR2400B is not intended to be powered by any supply other than Digium's own UL Listed power supply.
