Based IF static variable power and high current, high reliability requirements，this industry has been restricted of slip ring, cosmau with its years of experience in the development of in-depth research, breakthrough slip ring structure and process, greatly improve the large current IF slip ring FAQ, such as severe fever, poor heat, pressure drop, low reliability, not heat and other shortcomings.

COSMAU developed 400HZ IF slip ring has the following characteristics:
1) contact resistance, contact resistance of breaking the limits of conventional slip ring, the case does not include the cable resistance is milliohm or less, dynamic resistance is reached micro-ohm level, almost equal to cable resistance.
2) environmental adaptability, can be used for cold, fever zone, -40 to 80 degrees environment, extreme conditions up to 140 degrees.
3) temperature rise is small, these slip rings are usually stationary state work, reliable slip ring structure ensures IF minimal contact resistance, small voltage drop and power consumption, passive cooling can, low-carbon environment, low energy consumption.
4) overload, overload 125% for 10 minutes 150% overload for 1 minute, 200% overload for 10 seconds.
5) carries current, rated power ring carrying capacity 300A, while providing a mask signal path.
6) Long life, brush material used for military-grade brush material, a wear-resistant, low resistance, self-lubricating characteristics.
7) product complies with relevant military standard.
8) before shipping slip ring has been running, to ensure that customers can be achieved after the installation of a stable state.
9) Modular design, according to customer needs increase or decrease path, increase or decrease current, etc.
10) Features: Air power, usually working in the static state, which causes the internal current distribution uneven slip rings, high current operation, very easily lead to uneven heat, brush contact of a sharp deterioration in the state of the phenomenon. cosmau a distributed brush overcome the above problems, distributed brushes provide redundancy while ensuring adequate brush contact area, to overcome the effects of the current caused by uneven.
