I'm trying to roughly estimate the power consumption of this GVS112 galvo system. The system is based on two galvanometer drivers (for X and Y movements) and is powered by this GPS011 power supply as follows:
The thing is, the PSU is rated for 175W and the manual says: "The drive electronics require a split rail DC supply in the range ±15V to ±18V. The cards do not require an accurately regulated supply as the boards themselves have their own regulators. The maximum current drawn by the driver cards will not exceed 1.2 A rms on each rail".
In my case what would be the total power consumption? (Also the supply's efficiency is not given).
