The Delta MS300 3-phase VFD series is engineered for precision control of 3-phase motors using a 380–480V AC input. With advanced control features such as sensorless vector control (SVC), Safe Torque Off (STO), integrated RS-485 Modbus RTU communication, and a built-in 2k-step PLC, these drives are a reliable solution for a wide range of automation systems.
⚙️ Compact & High-Performance Motor Control
The MS300 3-phase drives feature both natural and fan cooling across compact frame sizes, making them ideal for OEM panels, conveyors, HVAC units, pumps, and packaging machines. Key performance improvements include faster response time, multiple motor switching, and energy-efficient design.
