PSU Capacity

Each PSU supports a different load figure.

PSU Type	Maximum Load Figure
PSU-S (for KX-TDE100 only)	64
PSU-M	128
PSU-L (for KX-TDE200 only)	512

Calculation Example (KX-TDE200)

	Equipment Type		Load Figure
KX-T7600 series DPT		48 units	48
Other DPT		2 units	8
SLC16		1 card	16
MSLC16		1 card	16
VPS		8 ports	8
Total			96

The total load figure is 96. As this is between 64 and 128, you should install the PSU-M. But if you expect expansion in the future, it may be better to install the PSU-L. There is no harm in installing a PSU that is larger than is required for the current configuration.
