Delta VFD2A8ME21ANNAA is an ultra-compact inverter from the ME series, designed for space-limited small power equipment with single-phase 200–240V input and 2.8kW rated output power, featuring miniature size and flexible installation options for tight spaces in commercial and light industrial applications. It adopts stable V/F control technology with a wide frequency range (0.1–400Hz) and basic speed regulation accuracy (±3% of rated speed), suitable for small motors in office equipment, medical devices, and mini automation machines that require compact drive solutions. The inverter has an ultra-small size (90×100×110mm), high power density (0.028kW/cm³), and lightweight design (net weight 1.5kg), enabling installation in confined spaces such as inside equipment cabinets or directly on small motors. It is equipped with comprehensive protection functions including overcurrent (200% of rated current for 0.1s), overvoltage (DC bus >500V), undervoltage (DC bus <200V), overload (150% for 60s), overheating (inverter module >90°C), and short circuit (IGBT protection), ensuring safe operation in small drive systems. The simple 2-button keypad allows for basic frequency adjustment and start/stop control, and the LED indicator provides real-time status monitoring (running, fault, standby). With its plug-and-play design, low electromagnetic noise (<52dB), and compliance with CE and UL safety standards, this inverter is ideal for small power equipment in medical, office, and light industrial settings requiring compact and reliable drive control.
