Strata CTX Configuration
Worksheet 7 – System Power Factor Check
2-44 Strata CTX I&M 06/04
Telephone/Device Power Factors
The power supply of each cabinet supplies a limited amount of power. Use the Worksheet below to
calculate the total Telephone/Device -24 VDC PF for each cabinet. Add it to the appropriate
cabinet in “Cabinet Power Factor Check” on page 2-45. Telephones do not have +5VDC PFs.
Note PF varies by number of telephones because of station paging limit of 32 telephones. Always
use “1.0” for DKT telephones when calculating PFs for individual cabinets.
