Using 1151B1 and 1151B2 Power Supplies
The 1151B1 and 1151B2 Power Supplies can be used to supply local power to ISDN-T 85xx and 84xx
series and 46xx series telephones connected to a media gateway and to the 302D Attendant Console that
requires auxiliary power for its display. The unit can supply power to adjunct equipment such as S201A
and CS201A speakerphones or a 500A Headset Adapter attached to any currently manufactured analog,
DCP, or ISDN-T telephone equipped with an adjunct jack.
CAUTION:
The power supply can be used only with telecommunications equipment, indoors, and in a
controlled environment.
The power supply has a single output of -48 VDC, 0.4 amperes and can operate from either a 120 VAC
60 hertz power source (105 to 129 VAC) or a 220/230/240 VAC 50 hertz power source (198 to 264 VAC).
Input voltage selection is automatic. The output capacity is 19.2 watts.
The power supply can be placed on a flat surface such as a desk. For wall-mounting, keyhole slots are
provided on the bottom of the chassis.
