4.9. Feedbacks
The Eagle HV can receive and process feedback input from diverse types of devices.
4.9.1. Feedback Supply Voltage
The DC-Eagle HV has two feedback ports (Main and Auxiliary). The DC-Eagle HV supplies
voltage only to the main feedback device and to the auxiliary feedback device if needed.
