Solar charger module

Solar charging control

For sucessful solar charged battery applications you need to match daily motor consumption with solar charging capacity at the worst time of year. The batteries (Ahrs) and solar panel capacity (W) are variables. The charging controller is 12V, or 24V, or higher. 


Bolt & bollard sequencing

Sequence applications

There are many examples of sequencing two subsystems 

  • Two gates operating Airlock mode
  • A bollard beneath the swing of a gate
  • Swing gate pair operating at night, then a barrier in day
  • A motorised bolt mounted on a swing gate leaf

Squence controller

In each case, one operation needs to be completed before it is safe to begin the next, and probably the same in reverse. It involves limit switches on both sub systems. Industrial systems use a supervisory controller and take feedback from the subsystems via a control bus like RS485.
