PSU Capacity

Each PSU supports a different load figure.

PSU Type Maximum Load Figure

PSU-M 128

PSU-L 512

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

Equipment Type

Load Figure

KX-T7600 series DPT 48 units 48

Other DPT 4 units 16

ESLC16 1 card 16

EMSLC16 3 cards 48

VPS 8 ports 8

Total 136

The total load figure is 136. As this is between 128 and 512, you must install the PSU-L.
