5.1 Stabilized Power Supply
The KM001 module can be used if the amplifier is connected to a symmetri-
cal unregulated supply voltage of "15.6...25.0 V. The module supplies the
two stabilized supply voltages internally to the amplifier. When installing the
KM001 module, attention should be paid to the marking (bridge 3 and bridge 4
on pin 1 and 2).
Pin assignment:
positive pole
negative pole
supply zero
5.2 DC-DC Converter
The manufacturer can mount a DC-DC converter onto the board for the oper-
ation of a single-pole supply voltage (battery). The voltage converter is suit-
able for operation on +9...+35 V (unstabilized).
Pin assignment:
positive pole
negative pole
The DC-DC converter decouples the internal operating voltages from the sup-
ply voltage.
