RECOM Power XFMR High-Performance Isolation Transformers

The RECOM Power XFMR High-Performance Isolation Transformers are a family of subminiature isolation transformers designed for use in isolated power supplies, signal isolation circuits, and gate-drive applications. The portfolio includes multiple transformer variants with different winding configurations and input/output voltage combinations to support a broad range of power conversion requirements. Available in both surface-mount (SMD) and through-hole (THD) packages, these transformers are suitable for automated assembly processes and can withstand standard reflow soldering temperatures.

The XFMR series includes bobbin-type transformers such as the RBE, RPE-021, and RBA-026 families, as well as RMR-series devices intended for regulated power supplies and IGBT gate-drive circuits. Single, dual, and triple primary and secondary winding options provide flexibility in converter topology design. Constructed using UL-listed materials and supporting operating temperatures up to +125°C on selected models, these transformers are intended for industrial, infrastructure, telecom, and automation applications requiring galvanic isolation.

Features of XFMR High-Performance Isolation Transformers

The XFMR series provides isolated power transfer in compact transformer packages. Multiple winding configurations, mounting options, and transformer variants support a wide range of power conversion and isolation requirements. Let’s go through its features in detail:

Transformer Portfolio and Variant Options

The XFMR family includes several transformer series designed for different power supply architectures. RBE transformers support common input/output voltage combinations, while RPE-021 and RBA-026 variants are intended for wide-input-voltage designs. RMR-series devices support regulated power supplies, including 5V-to-5V conversion and IGBT gate-drive applications.

Winding Configurations and Design Flexibility

The transformers are available with single, dual, or triple primary and secondary windings. These options provide flexibility when implementing isolated DC-DC converters, flyback supplies, gate-drive circuits, and custom transformer topologies. Multiple winding arrangements allow designers to optimize voltage conversion and isolation requirements for specific applications.

Compact Construction and Assembly Compatibility

The XFMR series utilizes a subminiature form factor suitable for space-constrained electronic systems. Devices are available in both SMD surface-mount and THD plug-in versions, supporting automated manufacturing processes. The transformers are designed to withstand the peak temperatures encountered in standard reflow ovens during PCB assembly.

Thermal Performance and Material Construction

The transformers are manufactured using UL-listed materials and support operating temperature ranges of -40°C to +70°C or +125°C, depending on the model. This temperature capability enables deployment in industrial environments where equipment may be exposed to elevated operating conditions and long-term thermal stress.

Isolation and Power Supply Applications

The transformer family is intended for galvanic isolation in power conversion systems. Different XFMR variants support isolated power supplies, wide-input-voltage converters, regulated low-voltage outputs, and IGBT gate-drive circuits. These capabilities enable implementation in industrial control systems, telecom infrastructure, measurement equipment, and energy-related applications.

Applications

RECOM XFMR High-Performance Isolation Transformers are used in industrial automation systems for isolated power distribution and control circuitry. In factory, building, and process automation equipment, they provide galvanic isolation between control and power domains. The transformers are also used in power generation and energy distribution systems where isolation and voltage conversion are required. Test and measurement equipment utilizes these transformers to isolate sensitive circuits and improve system safety. Additional applications include infrastructure equipment, networking hardware, and data and telecom systems, where compact transformer designs support isolated DC-DC converters, communication interfaces, and gate-drive power supplies.
