Preen Power AFC-33400 400kVA AC Power Source

Overview

The Preen Power AFC-33400 is a robust 400kVA three-phase AC power source delivering clean, precisely regulated power for mission-critical applications. Featuring double conversion technology with galvanic isolation and THD below 2% (optional <1%), the AFC-33400 is engineered for applications requiring the highest power quality and reliability.

The unit supports flexible output voltage configurations from 5–150V (phase-to-neutral) and 10–300V (line-to-line), with type-selectable frequency outputs according to application requirements. With high MTBF as a standalone unit up to 2000kVA capacity, comprehensive safety protection, and optional EMI filtering for EMC chamber applications, the AFC-33400 meets demanding industrial and military standards.
