Actuator power relay switch
Actuator power relay switch installed.
I ordered and received a two-relay card. I use a four-channel version to reverse the actuator power for forward and reverse movement.
The two-channel unit controls the actuator power supply battery connection. This unit is controlled from the same script that moves the actuator, hence the solar array.
When the script runs, now, the two-channel unit turns on and connects the battery bank to the boost converter. The boost converter boosts the battery voltage to that needed to drive the actuator, approximately 32vdc-36vdc.
Previously, the unit was connected by manual operation of a mechanical switch.
