The DC buffer amplifier is used for measuring the current and voltage while, at the same time, ensuring electrical isolation.

The measured values are output to the Sitras PRO central unit via fiber-optic cable (FO). Analog outputs are also available, such as
• for the display of section feeder current

• for the display of section feeder voltage
• for the display of test voltage (voltage in the feeder

section)

Sitras PRO BAplus, the DC buffer amplifier, can also be combined with one or two cable monitoring modules to implement a cable monitoring function.
