If you are familiar with the std SMB penthouse setup.....the electrified version replaces the rear "helper" compression springs with Linak linear actuators.....and adds some small dampers (they appear to be air dampers-dashpots.....haven't inspected these close up) near the crossbar pivots.
Here's what the actuators look like:
..and here is a few shots of them installed in member Bmerritt's van when he was doing his top transplant/install:
The SMB actuators are custom for SMB, and are 12V units with about 1100lbf (I think) of force each. Linak sells an electronic controller that synchronizes the lift for precision applications but that precision is not needed for a PH top...the actuators have synchronization switches or encoders (can't remember-had a discussion with Linak tech support last year) for non-precision applications.
