DPFT Unit The DPFT provides a means to connect eight selected CO lines to standard 
telephones in the event of a power failure (each DPFT requires an RSTU or 
PSTU PCB). There is no limit to the number of DPFTs installed, provided that 
the system power factor is not exceeded.
MDFB  The MDFB door phone option plugs into the DDCB or HDCB control box to 
provide a door phone. Three MDFBs can be connected to each DDCB or...

Worksheet 5 – System Power Factor Check
The Strata DK power supply was engineered for maximum cost efficiency to provide power for 
the most configurations. Because of this design, some power limitations exist when using old 
electronic-type telephones and/or telephone option hardware.
For example, only 24 3000-series telephones can be installed in a cabinet. Each telephone and 
PCB has a negative Power Factor (PF) and...

The power supply of each cabinet supplies a limited amount of power. For each cabinet, calculate 
the total Telephone/Device PF and add it to the appropriate cabinet in “Cabinet Power Factor, 
PCB/Telephone Device” on Page 4-38.
