York S1-6109897 Variable Frequency Drive Controller PGMD

The York S1-6109897 Variable Frequency Drive (VFD) Controller PGMD is a modern product used to control the speed and efficiency of HVAC motors. This VFD controller works on voltage of 208-240V and frequency of 60 Hz; it has NEMA 1 enclosure which offers protection and sturdy structure for indoor use. The main application of VFD is to control the motor speed in HVAC systems in order to control the flow rate and energy used. The VFD consist of a device that changes the frequency of the electrical power supplied to the motor, as well as the speed of the motor, to meet the varying demands of a system and hence increase efficiency and conform to the needed energy levels. This controller is particularly useful in applications such as air handling units, fan systems, and pumps where variable speed operation can result in large energy savings and improved system performance.
