Controller
The controller of the HVF-1k2 has been redesigned.
The sequencer, measurement, control, and regulation functions
are of course still available and tailored to the Sixty One
modules.
The fans for water cooling are now controlled via PWM, which
enables extremely quiet operation of the power amplifier. A
separate PWM port has been set up for the water pump so that
the pump and fans can be controlled independently of each
other.
A connection for a water temperature sensor has been added.
New HMI display concept!
The board also features a port for connecting an HMI (Human
Machine Interface) display. This can be installed in the
housing or operated separately.
A Raspberry is no longer required!
The power amplifier no longer needs to boot up an operating
system and is ready for use 2 seconds after being switched
on.
Another advantage is that there is no need to maintain the
Raspberry PI operating system.
