Technical Specifications

Main Features and Advantages

The Jefferson 511-0118-055 sets a high standard for power reliability with its fully encapsulated core-and-coil assembly, which encases windings in epoxy resin to deliver exceptional protection against moisture, dust, and corrosive agents prevalent in harsh industrial atmospheres, thereby extending operational life far beyond conventional ventilated designs and curtailing failure rates by over 40% in humid or chemically aggressive locales. This rugged construction, combined with integral electrostatic shields, effectively attenuates conducted and radiated noise, ensuring pristine voltage waveforms that prevent false triggers in relay logic or analog signal distortions in DCS loops—critical for maintaining the precision demanded in automated processes.

Versatile voltage tap configurations distinguish the Jefferson 511-0118-055, allowing field technicians to fine-tune primary connections across a broad spectrum of global standards without auxiliary buck-boost units, which not only simplifies inventory management but also enhances adaptability in multi-national facilities where grid variations are commonplace. Its compact wall-mount footprint optimizes panel space in tight control cabinets, while the NEMA 3R enclosure withstands environmental stressors like rain or sleet, enabling reliable deployment in exposed outdoor substations or washdown zones without the need for additional IP-rated housings.

Efficiency and sustainability are woven into the fabric of the Jefferson 511-0118-055, achieving up to 95% efficiency at full load through optimized silicon steel lamination and low-loss windings, which translate to measurable reductions in energy bills and carbon footprints for eco-conscious operations. Built-in thermal protectors and overcurrent safeguards provide layered defense against overloads, with resettable features that minimize nuisance trips and support seamless recovery in cyclic loads like conveyor drives. For automation integrators, the Jefferson 511-0118-055 offers unmatched ease of integration, compatible with standard DIN-rail accessories and pre-wired termination blocks that expedite commissioning, slashing setup times by hours. Collectively, these attributes forge a transformer that not only powers but elevates industrial systems, delivering superior electromagnetic compatibility, thermal resilience, and lifecycle economics that outshine generic alternatives in the competitive arena of control-grade power solutions.

Application Field

In oil and gas extraction sites, the Jefferson 511-0118-055 anchors remote instrumentation skids, converting erratic site voltages to stable 120/240 V feeds for solenoid valves and pressure transmitters, where its weatherproof enclosure and noise suppression directly counter the interference from VFD-driven pumps, averting measurement inaccuracies that could compromise safety interlocks and enabling precise flow regulation amid fluctuating upstream pressures. This targeted reliability addresses the isolation challenges of offshore platforms, facilitating uninterrupted SCADA polling that enhances predictive leak detection and operational continuity in unforgiving marine conditions.

Within pharmaceutical blending suites, the Jefferson 511-0118-055 powers cleanroom-rated mixers and peristaltic pumps, its encapsulated design ensuring zero outgassing or particulate shedding that aligns with stringent GMP protocols, while dual-voltage flexibility accommodates international R&D collaborations without retooling electrical schematics. By delivering flicker-free power, it stabilizes variable-frequency drives for agitator speed control, mitigating batch inconsistencies born from harmonic distortions and supporting validated processes that uphold product uniformity and regulatory traceability in high-stakes validation cycles.

For renewable solar inverter arrays, the Jefferson 511-0118-055 serves as a step-down hub for auxiliary monitoring panels, transforming elevated DC-derived AC to compatible levels for Ethernet switches and data loggers, its 50/60 Hz tolerance bridging regional grid discrepancies in hybrid microgrids. This resolves the voltage sag issues plaguing string inverters during peak shading events, empowering real-time yield optimization via stable sensor arrays that feed into AI-driven fault forecasting models. Spanning these vital domains—from wastewater treatment aeration controls to semiconductor wafer handling—the Jefferson 511-0118-055 methodically dismantles power quality barriers, fostering fault-tolerant architectures that amplify asset utilization, curtail energy waste, and propel sector-specific innovations toward electrified, resilient futures unhindered by electrical volatility.
