Delta VFD

Delta VFD L1 Series Variable Frequency Drives

The Delta VFD L series are sub-fractional low-cost AC Motor Drives. These inverters are specifically designed for applications with low power requirements. The VFD L series comes with a built-in EMI filter to efficiently reduce electromagnetic interference and to conform to the CE EMI directive.

The Delta VFD L inverters are designed to operate at 115VAC and 230VAC voltage categories. Only 1-Phase operation is supported by the 115VAC voltage class, with output power ratings of 200-400W. When operating in 230VAC class, 1-Phase operation has an output power range of 200W – 0.75 kW (20W – 1HP) while 3-Phase operation has an output power range of 200W – 1.5 kW (200W – 2HP).
