3-7. Power supply unit [PAC-SC51KUA]
PAC-SC51KUA supplies DC power of M-NET (23-32V) and 24V at TB2 and TB3 respectively; the former is for centralized
transmission use and the latter is for AG-150A operation and LAN function use.

When using PAC-SC51KUA as the power supplier for system controller, the capacity for system controller is
considered as follows.

Equivalent power consumption of controllers
PAC-SC51KUA is capable to supply equivalent power up to 5, therefore the maximum connectable number of system controller
is as follows.
*1: According to the system restrictions, PAC-SC51KUA can be connected to only one centralized controller.
As the air conditioner control system may combine all kinds of system controllers, the total power
consumption of system controllers need to count with Table 2.
For example, the controller system contains 1 AG-150A and 2 ON/OFF remote controllers (PAC-YT40ANRA) connected at
centralized control communication line.
Then the total power consumption is
1 x 0.5 + 2 x 1 = 2.5 < 5.
One P
AC-SC51KUA is therefore enough. The total power consumption should not exceed 5.

CAUTION
When applying Charge and/or Peak-cut function on AG-150A, Power Supply Unit (PAC-SC51KUA) is recommended to use.
AG-150A is possible to receive power from one of the Outdoor units, but there is a risk that the failure of power supply from
the Outdoor unit will cause AG-150A's functiondown on the whole system.
