48VDC Power Supply with Spade Tips
The PS-4800 is a 48 Volt DC power supply that can source at least 625 mA. It has a 5 foot DC output cord terminated with spade lugs.
This supply can be used to power up to three existing Model 154-8 Powerfail Bypass Units if the PBX “rectifier” (-48V supply) is being removed. For new installations, the appropriate Bypass Unit is the Dees Model 154A-8/PSU which comes with a plug-in power supply for the same price as the 154-8.
