KX-TDA100/200 Backup time
PCC-NBC
We
show the result of the calculation of the battery backup time of TDA System as
follows.
1.
Calculation condition
(1)Electrical discharge current (Same of the current
consumption of main unit)
<Condition>
- All slot mounting of card
(TDA100=7 PCS. and TDA200=12 PCS.) on TDA100/200.
- Maximum number of Telephone connects with new DPT(In
the case of S and M)
Maximum
number of Telephone connects with old DPT(In the case of L)
The use rate is about 20%.
(Same of the maximum of
power supply)
Therefore, the battery
backup time in the real operation does not become shorter than this.
(2)Battery capacity
and working time
It calculates as an example of the seal lead storage
battery of the Matsushita battery.
