NOTE:
One power supply will support one telephone with or without an adjunct.
The maximum loop range between the telephone and the power supply is
250 feet.
This power supply replaces the KS-22911-L1/2, 329A, and 353A DC Power
Supplies and the 2012D AC Transformer.
The MSP-1 power supply has a single output of -48 volt DC, 0.4 amperes, and can
operate from either a 120 VAC 60 Hz power source (105 to 129 VAC) or a
220/230/240 50 Hz power source (198 to 264 VAC). Input voltage selection is
automatic; that is, the power supply adjusts itself for the type of input voltage. The
output capacity is 19.2 watts.
