AC DISTRIBUTION PCB
The AC distlibution PCB is located on the AC subpanel. The AC distribution PCB
contains:
• Soft-start circuitty
• Fusing for the soft-sta1t circuit
• Fusing for the AC sense circuit and 48 VDC power supply
• Fusing for the optional 24 VDC balance-of-system power supply

Housekeeping Transformer
The housekeeping n·ansfo1mer, located in the magnetics compaitment, is a voltage
conversion device that transfonns 208 V AC to 480 V AC for use within the inve1ter
on 208 V AC models or n·ansfo1 ms 600 V AC to 240 V AC for use within the 600
V AC models. The 480 V AC models do not require this conversion since 480 V AC is
already present within the inve1ter.
Magnetics Compartment
The magnetics compartment contains the isolation n·ansfo1mer and the inductors .
• Isolation transfonner: The inve1ter comes equipped with an integral isolation
n·ansfonner. The isolation n·ansfo1mer is designed for class-leading inve1ter
efficiency.
• Inductor: The inductor is used to filter the AC wavefo1m generated by the
power module, effectively reducing high frequency noise.
