Performance

The Optimal Reactor Solution for High Frequency Motor Protection

Motor Protection:
When installed at the output of a high frequency VFD, R4L reactors limit voltage spikes that can break down motor insulation.

PMAC Motor Optimized:
Designed specifically with PMAC motor applications in mind, R4L high frequency reactors incorporate features to address concerns unique to these applications.

High Frequency:
Thermally designed to withstand frequencies that would burn other inductors (up to 400 Hz), R4L reactors utilize advanced, proprietary materials to minimize heating and high current saturation.

Inductance for High Frequency:
Since an inductor’s impedance is directly proportional to frequency, high frequency applications often require lower inductances. R4L reactors offer 1.5%, 3%, 5%, and 7% impedances, calculated at 200 Hz and 480 V.

When combined with the RSL reactor product line (rated to 200 Hz), an extended range of impedance values are realized for high frequency applications.

Extended System Life and Reliability:
CTM R4L reactors reduce voltage stress and excess heat not just for the motor, but for all other load side components, greatly extending the life and reliability of the entire system.

Inductor Efficiency:
CTM Magnetics patented inductor technology enables highly efficient reactor designs for high frequency applications.

Power Density:
Innovative packaging and cooling systems, combined with highly efficient inductors enable unparalleled power density.

Liquid Cooling:
CTM Magnetics patented liquid cooled technology enables higher thermal efficiency, power density, and performance. With liquid cooling, 97% of the reactor heat is captured by the coolant with only 3% released to ambient. This reduces the need for additional cooling and allows for more flexibility in locating reactors near temperature sensitive equipment.

Military Grade Shock & Vibration:
CTM liquid cooled R4L reactors have been tested and passed rigorous explosive and extreme shock & vibe military testing. RHF liquid cooled reactors are the optimal choice for mobile, marine, and military applications.
