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
