York MVVSD (Medium Voltage Variable Speed Drives) series drives are used on large, medium voltage York chillers, in ranges up to 10,000 horsepower. It is common to see VFDs used in low voltage chillers and compressors, but due to decreasing costs of electronics, medium voltage VFDs are becoming more common because of the potential energy and mechanical savings on medium voltage chillers and compressors. For further information on how VFDs can save energy on variable torque applications, click here.
York MVVSDs are actually manufactured by Toshiba and brand labeled by York. They are part of the Toshiba (Tosvert 300MVi) T300MVi generation of Medium Voltage VFDs. EMA is a factory certified service provider on the Toshiba T300MVi and T300MV2 Medium Voltage VFDs.
Most of the “guts” are the same between a standard Toshiba Medium Voltage VFD and the York MVVSD but there are a few minor differences: The Toshiba T300MVi and T300MV2 drives are painted grey, while the York MVVSD are painted dark green. The firmware and the HMI/Keypad are also different between the two.
EMA is one of the few third-party, factory-certified companies for Toshiba; we’re certified for field service, repair, and startup on both the Toshiba T300MVi and T300MV2.
