+(2.1±0.2 to 5.4 ± 0.5)V and has a connected feedback between the fan and the control unit.
Its attachment and connection of the connectors are similar to the FMD-01.
FMD-03 module
The FMD-03 module does not provide a passage for the fan motor supply voltage of +300V
but provides a passage for the outdoor unit electronics supply voltage of +15V (does not
have a built-in switching power supply of +15V). The module converts the input PWM signal
to the fan DC control voltage and has a connected feedback. Like the FMD-01 module, it is
not built into the box.
