Recom Power RH-0515D/HP

Summary of the RH-0515D/HP from Recom Power

The RH-0515D/HP from Recom Power is a compact, high-isolation DC-DC converter module designed for demanding industrial applications. Delivering regulated dual outputs of +15V and -15V at up to 33mA each, this 1W converter operates from a 5V nominal input (4.5V to 5.5V range). Packaged in a 7-pin SIP module measuring just 19.7mm x 7.1mm x 10.2mm, the RH-0515D/HP enables easy integration into space-constrained printed circuit boards, making it a compelling choice for designers needing reliable isolated power supply rails in compact industrial systems.

Main electrical specifications and performance attributes of the RH-0515D/HP

The RH-0515D/HP exhibits an impressive efficiency of up to 84% at full load, ensuring minimal power loss and reduced heat generation. Both outputs are current-limited to 33mA, with a dual polarity output configuration well-suited for analog, operational amplifier, and signal chain requirements. The expanded RH/RK Series architecture includes optional continuous short-circuit protection—distinguished on this model by the “/P” suffix—helping to safeguard not only the converter but also the connected circuit. For project-critical timing, the maximum capacitive load is specified to guarantee unit startup under 1s without device damage when driven by a full resistive load. The SIP7 form factor and industry-standard pinout streamline the design-in process for engineers.

Isolation rating, certifications, and safety standards of the RH-0515D/HP

The RH-0515D/HP is engineered for robust safety isolation, providing galvanic isolation up to 4kVDC for 1 second—a substantial protective barrier for sensitive control-side electronics interfacing with higher voltage domains. This model series is certified to IEC/EN/UL 60950-1 as well as CSA/CAN C22.2 No. 60950-1-07, addressing international safety standards for IT and industrial equipment. The flame-retardant case employs UL94 V-0 rated material, further supporting compliance in safety-critical environments. The device is RoHS3 compliant and REACH unaffected, simplifying global environmental and health compliance for your end product.

Thermal, structural, and environmental factors relating to the RH-0515D/HP

Designed with industrial field deployments in mind, the RH-0515D/HP offers a broad operating temperature range from –40°C to +90°C (ambient, free air convection). This wide envelope ensures reliable operation in both harsh cold and elevated ambient environments typical of control cabinets or outdoor installations. The robust SIP7 package not only facilitates efficient airflow and heat dispersion but also aligns with automated assembly workflows, thanks to tight dimensional tolerances and stable pin orientation.

Installation guidelines and recommended uses for the RH-0515D/HP

Integration of the RH-0515D/HP into system-level designs is straightforward, leveraging the detailed mechanical drawings and recommended PCB footprint provided by Recom Power. Inverter gate drivers (IGBT drivers) are a key application, where the high isolation voltage and dual rail output mean the converter can directly support the floating supplies required by gate driver ICs. The device’s electromagnetic compatibility enables straightforward compliance with EN55032 via appropriate filtering (design notes are available), aiding engineers in meeting emission class targets without additional complexity. For applications facing potential output shorts, the continuous short circuit protection model variant (/P or /HP) should be considered to ensure system resilience and reduced maintenance needs.

Alternative and comparable models to the RH-0515D/HP

When evaluating alternatives to the RH-0515D/HP, consider other members of the Recom Power RH and RK Series, which offer variants with different input voltages, output configurations, and combinations of protection and isolation ratings. For new medical-grade designs, the REM1 series from Recom Power is recommended as a preferred alternative, featuring enhanced certifications and performance suited to medical environments. Care should be taken to match both the electrical characteristics and isolation/safety certifications of the RH-0515D/HP if substituting in sensitive or regulated markets.

Conclusion

The RH-0515D/HP from Recom Power delivers a compelling mix of high isolation, proven safety compliance, robust environmental performance, and compact design. Its thoughtful feature set aligns well with the practical requirements of engineers developing industrial control, signal conditioning, or IGBT driver circuits. By understanding its capabilities, certifications, and application best practices, engineers and procurement professionals can confidently integrate the RH-0515D/HP in new or legacy projects—and, when necessary, identify the most suitable alternatives within the Recom Power portfolio to ensure uninterrupted supply chain performance.
