3-15. Transmission booster [PAC-SF46EPA]
The Outdoor unit supplies transmission power 30VDC for the indoor-outdoor transmission line at its connector TB3 and TB7.
The power is consumed by the Indoor unit, ME remote controller, and System controllers. When the total quantity of Indoor
units, and ME remote controller, and System controllers is over 40, or when transmission power supply is not enough, the
transmission booster PAC-SF46EPA should be designed into the air-conditioner system to ensure the system communication.
Indoor units sized P200 and 250 are counted as 2 units.
Table 1 The equivalent power consumption
1. Designing PAC-SF46EPA into an air-conditioner system.
Taking the power consumption of Indoor unit sized P15-P140 as 1, the equivalent power consumption or supply of others are
listed at T
able 1 and T
able 2.
Table 2 The equivalent power supply
Transmission booster PAC-SF46EPA has equivalent transmission power 25.
With the equivalent power consumption values in T
able 1 and Table 2, PAC-SF46EPA can be designed into the airconditioner
system to ensure proper system communication according to A, B, C.
(A) Firstly, count from TB3 at TB3 side the total quantity of Indoor units, OA processing units and ME remote controller
,
and System controllers. If the total quantity reaches 40, a PAC-SF46EPA should be set. In this case, Indoor units
sized P200 and 250 are counted as 2 indoor units, but MA remote controller(s), PZ-61DR-E, and PZ-43SMF-E are
NOT counted.
(B) Secondly, count from TB7 side to TB3 side the total transmission power consumption. If the total power consumption
reaches 32, a PAC-SF46EPA should be set. Y
et, if a PAC-SC51KUA or another controller with a built-in power supply,
such as PAC-YG50ECA, is used to supply power at TB7 side, count from TB3 side only.
(C) Thirdly, count from TB7 at TB7 side the total transmission power consumption, If the total power consumption reach-
es 6, a PAC-SF46EPA should be set.

*If PAC-SC51KUA is used to supply power at TB7 side, no power supply need from Outdoor unit at TB7, Connector TB3 itself will therefore have 32. Not
applicable to the PUMY model.
*1 AE-200E/AE-50E has a built-in function to supply power to the M-NET transmission line. The amount of power that an AE-200E or an AE-50E can supply is
equivalent to the power required by an MN converter (CMS-MNG-E) that is used for maintenance.
