1.3 Principle of Operation
BP4610 1-4
The BP4610 is composed of the four major blocks.
<1> DC power supply block
The DC power supply block has a variable DC voltage function that works in conjunction with
the power factor improvement function and voltage limiter value. Various control power
supplies and positive/negative DC power supplies for the amplifier block can be created while
improving the power factor for the power supply input. The output voltage range shift function
is enabled by the variable DC voltage function
. ( Refer to “4.4.1 Shifting the output
voltage range” . )
<2> Signal sources
This is an internal signal source that enables the sequence function and DC+AC output. An
external input and internal signal can be used added together.
<3> Amplifier block
The amplifier block has a response calibration function and a protection circuit function. It
outputs signals from an internal signal source or external signal source after amplifying them.
Two types can be selected from among response characteristics, fixed characteristics, and user
adjusted characteristics (response calibration function). If user adjusted characteristics is
selected, the response characteristics can be adjusted according to the load conditions. (
Refer to “4.10 Response Calibration” .)
<4> System control block
This block is in charge of the user interface, etc.
