Recom Power RD-1215D

Summary of RD-1215D DC/DC Converter

The RD-1215D, manufactured by Recom Power, is a compact, isolated DC/DC converter module designed to deliver efficient dual output power from a single input rail. This module provides ±15V output at up to 66mA per channel, with a total output power rating of 2W. The RD-1215D is built around the needs of system designers requiring reliable bipolar power rails in a range of industrial and instrumentation environments. With its wide input voltage range of 10.8V–13.2V, the device is especially suited to systems using 12V input sources.

Main Characteristics and Benefits of RD-1215D

The RD-1215D offers several critical features for power system architects:

Dual ±15V outputs, supporting balanced supply requirements for analog and mixed-signal systems.

Industry-standard SIP7 package for straightforward PCB mounting and space efficiency.

High power conversion efficiency, up to 87%, reducing heat dissipation and system losses.

Optional variants with continuous short-circuit protection and increased isolation (suffix “/P” for protection and “/H” or “/HP” for 2kVDC isolation).

Basic isolation rating of 1kVDC (optionally 2kVDC), supporting safety and system isolation demands.

UL94 V-0 rated package materials and a robust internal design for use in stricter environments.

Full power delivery across the temperature range of -40°C to +85°C, extendable up to +100°C with output derating.

Electrical and Thermal Characteristics of RD-1215D

The RD-1215D is an unregulated converter, optimized for stability and predictable performance under typical industrial loads. Efficiency measurements at nominal input and full load reach up to 87% at 25°C ambient, minimizing power waste and simplifying thermal management tasks in dense assemblies. The converter’s start-up into maximum capacitive loads is achieved in less than one second, protecting the converter during system initialization. The robust design permits reliable operation in environments with wide ambient temperature fluctuations, a vital factor for field equipment and installations with minimal environmental control.

Physical Dimensions and Installation Guidelines for RD-1215D

Integration is straightforward thanks to the SIP7 package, a well-established industry footprint that provides an optimal balance between size and handling robustness. Designers will find clear dimension drawings and recommended footprint layouts in the product documentation; tolerances are tight (±0.5mm for major dimensions) to facilitate automated assembly processes. System engineers should verify the mechanical envelope and footprint compatibility with their target PCB layout, especially in multichannel or multi-converter applications where board real estate may be at a premium.

Application Scenarios and Intended Uses of RD-1215D

The RD-1215D is engineered to solve the challenge of generating dual, isolated ±15V rails from a 12V supply—a common requirement in analog front-ends, industrial sensor interfaces, small-scale measurement instruments, and isolated operational amplifier circuits. Its dual-output capability and isolation features are invaluable in scenarios needing stable reference voltages and noise isolation, such as analog signal processing, mixed-signal conversion, and the supply of operational amplifiers or A/D converters within the same enclosure.

Alternative or Substitute Models Comparable to RD-1215D

When evaluating sourcing and risk mitigation, design engineers and procurement specialists should be aware of alternative models within the same series or from different brands that provide similar specifications. Within Recom Power’s own RD series, models like the RD-1515D or RD-2415D can be considered for higher input voltages (15V or 24V respectively) while maintaining the ±15V dual outputs and similar SIP7 form factor. Additionally, other manufacturers offer competing SIP7 dual-output DC/DC converters with comparable isolation ratings and output parameters; careful review of isolation voltage, efficiency, and protection features is recommended to ensure design compatibility when substituting.

Regulatory Compliance, Safety Approvals, and Reliability of RD-1215D

The RD-1215D meets essential compliance criteria for international markets, including RoHS3 and REACH directives. Safety standards EN60950-1 and IEC60950-1 are supported, making the RD-1215D suitable for commercial and industrial electronic system designs. The standard isolation rating of 1kVDC, with optional 2kVDC, ensures safe separation between input and output, essential for meeting system safety standards and electromagnetic interference requirements. The use of UL94 V-0 materials further contributes to the suitability of the RD-1215D in demanding operations where flame resistance is vital.

Conclusion

For engineers designing analog, mixed-signal, or measurement systems that rely on stable, isolated dual-supply voltages, the Recom Power RD-1215D presents a robust, efficient, and easy-to-integrate solution. Its balance of electrical performance, isolation, certified safety, and practical packaging position it as a reliable building block in modern industrial and instrumentation platforms. Evaluating the RD-1215D alongside equivalent models allows engineering and procurement teams to optimize their design and sourcing strategies, securing supply-chain flexibility without sacrificing system integrity.
