Mini Power Centers

A mini power center is a compact, self-contained power distribution unit that combines a transformer, primary and secondary overcurrent protection, and a panelboard within a single enclosure. It steps down a facility’s main voltage (typically 480 V or 600 V) to a lower utilization voltage such as 208/120 V for lighting and receptacle loads. Rex Power Magnetics mini power centers are designed for simplicity, safety, and reliability, making them ideal for localized or temporary power distribution in industrial, commercial, and construction environments.

Mini power centers are used wherever local low-voltage power distribution is required from a higher-voltage source. Common applications include industrial manufacturing lines, construction sites, temporary power setups, maintenance areas, and equipment rooms. They are also widely used in data centers, laboratories, and commercial buildings where isolated distribution zones are beneficial. Rex Power Magnetics designs each mini power center for durability and safety in both permanent and portable applications.

Mini power centers eliminate the need for separate transformer and panelboard installations, reducing space requirements and installation time. They arrive as pre-wired, factory-assembled units that can be quickly mounted and connected. This integrated design simplifies coordination between components, ensures proper short-circuit ratings, and improves electrical safety. Rex Power Magnetics mini power centers offer a clean, compact solution for distributing low-voltage power close to the point of use — perfect for retrofits, plant expansions, or modular construction projects.

Each mini power center integrates an encapsulated dry-type transformer with primary and secondary circuit breakers, a distribution panelboard, and a NEMA-rated enclosure. The entire assembly is mounted within a ventilated steel or stainless steel enclosure designed for optimal cooling and accessibility. All internal wiring and protective devices are factory-tested to ensure reliable, code-compliant operation upon installation.

Yes. Outdoor-rated models are supplied with weatherproof NEMA 3R, 4 or 4X enclosures and are built to withstand temperature fluctuations, rain, dust, and humidity. For particularly harsh or corrosive locations, optional stainless steel can be specified. Proper installation, including grounding and ventilation clearances, ensures reliable operation in all environmental conditions.

Yes. Rex Power Magnetics offers fully customized mini power centers to meet specific electrical and mechanical requirements. Options include custom voltage ratios, kVA ratings, circuit configurations, panelboard layouts, and enclosure materials. Additional accessories such as branch breakers and surge suppression can be integrated upon request. Each customized unit is engineered, assembled, and tested to the same rigorous standards as standard models, ensuring consistent reliability and safety across all installations.
