- Page 14 CONTROLLER DIMENSIONS The maximum thickness of the controller is 15.8mm (measured from bottom of PCB to top of components, including any underside components & leads). We recommend clearances of: • 5mm from bottom of PCB - if mounting on a metal plate we also recommend a layer of suitable insulation material is added to the mounting plate surface.
- Page 15 APPLICATION NOTES USING THE CONTROLLER WITHOUT BUTTONS ATTACHED This is very straightforward by following the steps below : • Firstly setup the controller/display system with the buttons. With controls attached and display system active make any settings for colour and image position as required then switch everything off. •...
- Page 16 Brightness: There are various methods for brightness control and it is important to consider the specifications for the inverter to be used. Generally the situation is: • Brightness can controlled by using a resistor or VR (Variable Resistor). • Brightness controlled by adding a circuit such as PWM (Pulse Width Modulation). •...
