Trane DRV01978 25HP Variable Frequency Drive 460V TR150P18KT4E20H4XXCX

The Trane DRV01978 Variable Frequency Drive is a variable frequency control component that modulates the speed of a motor by changing the frequency and voltage input to equipment to which it is connected. It adds a 25-horsepower capacity with an electrical rating of 460 V and a TR150P18K4E20H4XXCX drive-up configuration to adjust the operating motor to system and ensure accurate operation. It is used in HVAC systems, such as air handlers, pumps, and fan-driven equipment, where variable speed control is needed. The drive allows controlled energy use, lower mechanical losses, and constant operation of the system.
