Delta VFD2A7ME43ANNAA is a compact inverter from the ME series, engineered for small drive systems with three-phase 380–460V input and 2.7kW rated output power, featuring easy installation and comprehensive protection functions for reliable operation in light industrial applications. It adopts stable V/F control technology that ensures smooth speed regulation (±2% of rated speed) and reliable performance for small motors in fans, pumps, and mini automation devices, eliminating the complexity of vector control while maintaining sufficient accuracy for light-duty loads. The inverter has a compact design (120×140×150mm) with a detachable terminal block for easy wiring and maintenance, and the DIN rail mounting design simplifies installation in control cabinets or directly on machinery. It is equipped with full protection functions including overcurrent (200% of rated current for 0.1s), overvoltage (DC bus >800V), undervoltage (DC bus <400V), overload (150% for 60s), overheating (inverter module >95°C), phase loss (input), and short circuit (IGBT protection), ensuring safe operation even in abnormal working conditions. The user-friendly 3-button keypad allows for basic parameter adjustment (frequency, acceleration/deceleration time) and status monitoring (output frequency, current, voltage), and the parameter copy function (via external USB adapter) facilitates quick commissioning of multiple units in production lines. With its robust construction, low power consumption (<2W in standby mode), and long service life (MTBF >50,000 hours), this inverter is widely used in small drive systems in food processing, packaging, and light manufacturing industries.
