Delta VFD2A7MS43ANSAA is a general-purpose compact inverter from the MS series, offering cost-effective and stable drive performance for light industrial applications with three-phase 380–460V input and 2.7kW rated output power. It adopts stable V/F control technology that ensures reliable operation (0.1–400Hz frequency range) and basic speed regulation accuracy (±3% of rated speed), meeting the requirements of small fans, pumps, and conveyors in light manufacturing and commercial applications without the need for advanced control features. The inverter has a compact structure (110×130×140mm) with a durable plastic enclosure and metal mounting plate, providing mechanical protection in industrial environments while keeping weight low (1.9kg). It is equipped with standard protection functions including overcurrent (instantaneous protection), overvoltage (DC bus protection), undervoltage (input power protection), overload (electronic thermal relay), overheating (inverter module protection), and short circuit (IGBT protection), ensuring safe operation in small drive systems. The simple wiring design (screw terminal block) and plug-and-play installation reduce commissioning time, and the low power consumption in standby mode (<1.5W) enhances energy efficiency. With its stable performance, high durability (MTBF >40,000 hours), and affordable pricing, this inverter is widely used in small centrifugal fans, gear pumps, and belt conveyors in food processing, packaging, and light manufacturing industries, providing a reliable and cost-effective drive solution for light-duty loads.
