RECOM’s RPA20-FR Series: High-Efficiency DC/DC Converters for Rail and Industrial Applications
RECOM, a leader in power electronics, has introduced the RPA20-FR series , a groundbreaking range of high-efficiency DC/DC converters designed specifically for demanding rail and industrial applications. These compact converters deliver exceptional performance in a miniature package (1.6” x 1” x 0.4” or 40.6mm x 25.4mm x 10.2mm), making them ideal for space-constrained environments. With compliance to stringent industry standards like EN 45545-2 and EN 50155, the RPA20-FR series ensures reliability and safety in harsh operating conditions.
DC/DC converters Compact Design Meets Superior Performance
The RPA20-FR series stands out for its ability to deliver 20W of power across a wide input voltage range of 36VDC to 160VDC (with a peak tolerance of 200VDC for 1 second). This makes it suitable for rolling stock applications with nominal input voltages of 48V, 72V, or 110VDC 1. Despite its small form factor, the series offers fully regulated, low-noise outputs with minimal deviation, ensuring consistent performance even in extreme temperatures ranging from -40°C to 70°C (and up to 105°C with derating ).
Available output voltages include 5V, 5.1V, 12V, 15V, and 24VDC , all of which are trimmable by +20%/-10% minimum. Additionally, dual-output options such as +/-5V, +/-12V, and +/-15VDC cater to diverse application needs.
DC/DC converters Advanced Features for Enhanced Reliability
The RPA20-FR series is equipped with advanced features that enhance usability and protection:
1. Remote ON/OFF Control
Users can control the converter remotely using either positive or negative logic, providing flexibility in system integration.
2. Under-Voltage Lock-Out
This feature ensures the converter operates only within safe voltage thresholds, protecting both the device and connected systems.
3. Surge Protection
A dedicated protection module, the RSP150-168 , safeguards against voltage surges in compliance with RIA12 and NF F01-51 standards , ensuring robust performance in unpredictable environments.
4. Reinforced Isolation
With 3kVAC/1min reinforced isolation , the series meets stringent safety requirements, making it suitable for audio/video, IT, and industrial applications.
Compliance with Industry Standards
The RPA20-FR series is engineered to meet the rigorous demands of rail and industrial sectors. Key certifications include:
- EN 45545-2 : Ensures fire safety in railway applications.
- EN 50155 : Compliance for electronic equipment used in rolling stock.
- UL/IEC/EN 62368-1 : Safety standards for audio/video and IT equipment.
- EN 50121-3-2 : EMC compatibility for railway applications.
- EN 60068-2-1 : Resistance to dry and damp heat.
- EN 61373 : Shock and vibration resistance for railway environments.
These certifications highlight the series’ suitability for critical applications where reliability and safety are paramount.
Applications Across Diverse Industries
While the RPA20-FR series is optimized for rail applications, its versatility extends to other industries, including:
- Industrial Automation : Reliable power solutions for machinery and robotics.
- Energy Sector : Ideal for renewable energy systems requiring stable DC/DC converters.
