ENERJİTEM 100kVA Isolation Transformer, IP42, 480Vac Input / 208Vac Output

ENERJİTEM 100 kVA IP42 Box-Type Isolation Transformer, 480Vac Input / 208Vac Output

The ENERJİTEM 100 kVA IP42 Box-Type Isolation Transformer, with a 480Vac input and 208Vac output, is a high-capacity system designed to enhance power quality and voltage transformation at the facility level. This transformer combines full galvanic isolation with a substantial 100 kVA power rating to safely convert a high North American standard 480V industrial voltage into a standard 208V three-phase lower voltage.

This heavy-duty unit offers 2.5 times the capacity of a 40 kVA model, enabling it to power entire facility subpanels, large rows of data centers, or high-power commercial infrastructure.

Strategic Engineering of the 100 kVA Capacity

Powering Facility Subpanels: The substantial 100 kVA capacity allows this transformer to serve as the primary power source for localized distribution panels, providing isolated 208V power to dozens of machines, servers, or tools simultaneously.

Excellent Inrush Current Tolerance: The large magnetic core readily absorbs severe instantaneous current surges, known as inrush currents, generated when multiple large motors, heavy pumps, or commercial chillers start up concurrently.

Clean and Stable Ground Reference: By physically separating the primary and secondary circuits, the transformer establishes a new, dedicated neutral-to-ground reference point on the 208V side. This helps eliminate ground loop currents entirely, which can cause data corruption and communication errors in sensitive microprocessor-based control systems.

Purpose of the IP42 Boxed Enclosure

Protection Against Heavy Industrial Debris: The robust, reinforced steel enclosure prevents solid objects larger than 1.0 mm, such as metal filings, loose copper wires, small hand tools, or insects, from entering the high-voltage internal coils or main busbars.

Drip Protection with High-Flow Ventilation: The IP42 design features specialized louvered ventilation paths that allow for the substantial airflow required to cool a 100 kVA transformer core, while preventing vertically falling water droplets up to a 15-degree angle from entering.

High Personnel Safety: Housing a 100 kVA transformer within a grounded metallic enclosure is critical for arc flash containment. The sturdy, grounded frame ensures the safety of operators and maintenance crews from dangerous high-energy exposure.

Key Industrial Applications

This specific 480V to 208V, 100 kVA configuration is essential for high-capacity, low-voltage infrastructure.

High-Density Data Centers: Stepping down facility 480V power to feed large rows of 208V three-phase Power Distribution Units (PDUs), while fully filtering out facility-level electrical noise and harmonic distortions.

Large Commercial Kitchens and Food Processing Plants: Operating extensive arrays of high-consumption commercial ovens, localized refrigeration rooms, and automated industrial packaging systems that require a stable 208V three-phase power source.

Medical Complexes and Imaging Centers: Providing clean, isolated, and low-leakage 208V power for central diagnostic devices, laboratory systems, and medical imaging equipment that cannot tolerate grid harmonics.

Manufacturing Workshops and Industrial Plants: Powering entire banks of 208V CNC tools, heavy-duty 3D production printers, or automated conveyor lines within a standard 480V factory environment.
