Thanks for the replies.
Yes it is linear actuator, the position is not that accurate, I have 2 reed switches that is mounted on the side of the actuator for positioning control (2 positions only)
It took me 3+ mins to extend to the max and 40 secs to retract fully (with 1 tonne load)
using 24VDC PS (back EMF til 60VDC)
With that kind of load, it was pretty scary to see the descent, not to mention about the sound the actuator created.
I'm caught in the situation whereby I can only solve the problems in terms of pure electronics.
I have yet to try out AI_the_Man method and the short method.
Desperately I will have to temporary stick to 5V PS and upgrade the capacitor and finger-crossed it may last.
