PSU Capacity
Each PSU supports a different load figure.
PSU Type
PSU-M
PSU-L
If the total load figure is greater than 128, you must install the PSU-L. If the total load figure is less than 128,
but you expect expansion in the future, it may be better to install the PSU-L instead of the PSU-M. There is no
harm in installing a PSU that is larger than is required for the current configuration.
Calculation Example
KX-T7600 series DPT
Other DPT
ESLC16
EMSLC16
VPS
Total
The total load figure is 136. As this is between 128 and 512, you must install the PSU-L.
