Even minor power fluctuations can compromise critical measurements in sensitive laboratory equipment. Phonix addresses this challenge with the HRF15 digital series, a 15W high-voltage DC-DC converter engineered for exceptional stability and precision. The Phonix power supply integrates PMBus™ over I2C, allowing engineers to program both voltage and current outputs easily, providing a reliable foundation for configuration, control, and monitoring.
Instruments such as mass spectrometers, scanning electron microscopes, and transmission electron microscopes benefit from the digital interface, which provides real-time visibility into system health while reducing integration and setup time. The intuitive GUI simplifies commissioning, and advanced diagnostics convert complex operational metrics into actionable insights that protect sensitive instruments and maintain continuous operation.
The HRF15 delivers ultra-low ripple down to 0.001% (10ppm) and maintains stability at 10ppm per hour, ensuring consistent output for noise-sensitive applications. Its low 25ppm/°C temperature coefficient and exceptional line and load regulation keep power stable under varying input voltages and load conditions, meeting the stringent demands of precision research.
The HRF15 has proven reliability in diverse environments. From outdoor automated gate systems and LED street lighting networks to sensor-driven measurement platforms and high-vibration electric racing vehicles, it provides stable, uninterrupted power while integrating intelligent connectivity for critical applications. Engineering teams can also leverage PMBus control for automated monitoring and configuration.
Every application has unique requirements, so Phonix provides custom-configured solutions. Whether adjusting standard products or developing entirely new assemblies, engineering support spans design, production, and implementation. Housings, cables, connectors, and terminal boxes are seamlessly integrated to ensure each solution fits precisely.
The compact design measures 33 x 72 x 161 mm and weighs 465g, making integration into space-constrained setups straightforward. Each unit provides 15W from a +24VDC input, with fully adjustable constant current and constant voltage modes across 0–100%. Standard output voltages of 10kV, 12kV, and 15kV, combined with UL61010 and UL62368 certifications, ensure both performance and compliance for demanding applications.
The HRF15 digital series is available immediately with a three-year warranty, offering engineers a high-precision, digitally controlled Phonix power adapter solution that combines stability, advanced monitoring, and peace of mind.
