Electrical Specifications
The mount is completely powered by the power supply units inside the included mount electronics cabinet. The
maximum voltage inside the mount is 48VDC. The cabinet needs to be connected to a standard 110/230VAC
power socket or an appropriate UPS (uninterruptable power supply).
Typical power consumption during tracking: ~50-200W
Peak power consumption (acceleration, wind gusts, …): up to 500W
ASA recommends using a UPS with 1000VA or more (not included) fo
r the mount’s power supply.
Suitable UPS is available at ASA.
