HMI display

• This need to display the voltage, current, time , power if possible,

• Switch (pot?) to dial current, voltage and adjust parameters

Control module

• Current control 0 – 150 A (100mV shunt)

• Voltage control 5 – 150 V

• Cooling fan control PWM? 24V 500mA each

• Power control if possible

• Transient not required

PSU

• We have many power supplies available

Power modules

• We have and they take a voltage input and have a shunt to control current.

Documentation
