Overview

The Hammond Power FS350MQMJ is a general-purpose enclosed control transformer designed for industrial control circuits. This 350 VA unit converts primary voltages of 240x480 V to secondary voltages of 120x240 V, making it ideal for powering control systems, relays, contactors, and other low-voltage devices in manufacturing plants, HVAC systems, and automation applications. Constructed with computer-designed copper wound coils and a single core, the FS350MQMJ ensures efficient voltage transformation with convection air cooling for reliable operation. Its enclosed design protects internal components from dust, moisture, and physical damage common in industrial environments. The transformer meets UL, CSA, and NEMA standards, providing durable performance in demanding conditions. With a compact footprint, the FS350MQMJ integrates seamlessly into existing electrical panels and control enclosures. Its single-phase, common core design supports linear loads at 50Hz or 60Hz frequencies, offering flexibility for global applications. Whether used in motor control centers, lighting systems, or process automation, this transformer delivers stable voltage output for consistent control circuit operation.
