Delta ME300 VFD – 1-Phase Compact AC Drive (0.5–3 HP) | STO, Built-in Braking, PID, and SVC Control

The Delta ME300 VFD 1 phase models – VFD2A8ME21ANNAA, VFD4A8ME21ANNAA, VFD7A5ME21ANNAA, and VFD11AME21ANNAA – are next-gen compact vector drives built for 3-phase motor control from a 1-phase 230V AC input. Designed with Delta’s superior drive technology, these models offer precise speed regulation, high torque performance, and advanced automation features.

With built-in Safe Torque Off (STO), Modbus communication, DEB (Deceleration Energy Backup), and support for both induction and permanent magnet motors, the ME300 series drives boost reliability in critical operations. Their ultra-compact, screwless terminal design makes them perfect for space-limited panels and OEM equipment.
