Power braking resistors model ROS

These resistors are supplied in the version protected by a galvanized steel grid case with an open bottom.
They are made up of RFC type resistors consisting of a cylindrical ceramic support with the resistive wire winding.
The external protection of the resistor consists of a ceramic cement lining.
These resistors are used in start up and adjustment of motors, in electric braking devices and in load systems for generating sets, testing benches, suppression of harmonics and grounding of the star centre.

USE AS ANTI-CONDENSATION HEATERS

These resistors may be used as anti-condensation heaters for electric control panels.
