| Overview Motor manufacturers that use variable speed drives for flexibility and high performance can experience corona related problems. PWM inverters can create high voltage spikes exceeding 1600 volts. Minco has answered the call with a corona resistant RTD. This RTD is specifically designed for the latest generation of variable frequency drives for AC motors. Minco uses special materials and manufacturing techniques to create an RTD that is virtually corona-proof, eliminating the need for expensive reactors or filters for the sensors.** • Designed for AC motors with variable frequency drives (VFD) • Proprietary design* resists detrimental effects of corona • Protect expensive motors with an inexpensive overtemperature warning system • Tested to 10,000 VAC without failure • Widths from 0.305" to 1.25" • Lengths from 7" to 30" Specifications - Model S8025 Temperature: 180°C (356°F); Class H.
