48VDC Power Supply with Spade Tips
The PS-4800 was a 48 Volt DC power supply that could source at least 625 mA. It had a 5 foot DC output cord terminated with spade lugs.
This supply had been used to power the Model 154-8 Powerfail Bypass Unit. If the PBX does not already have an external -48V supply, then the appropriate Bypass Unit is the Dees Model 154A-8/PSU which comes with a plug-in power supply for the same price.
Please contact Dees Communications if you have a specific application requiring this product.
