{"title":"Premium PSU Railway \u0026 Industrial Power Products","description":"\u003cp\u003ePremium PSU railway and industrial power products are engineered in Barcelona since 1981, making Premium PSU a market leader in power conversion for demanding rail and industrial environments. The range spans EN50155 certified off-the-shelf products alongside a portfolio of over 900 custom designs, giving engineers a proven starting point or a tailored solution depending on project requirements.\u003c\/p\u003e\n\n\u003cp\u003eThe featured selection below draws from three of the range's strongest categories. DC\/AC inverters, including the ODS series, are built for 110Vdc railway and industrial SCADA applications where reliable voltage conversion is critical, even in harsh operating conditions with wide temperature ranges, vibration exposure and long duty cycles. DC\/DC converters handle the voltage regulation needs common across rolling stock and control systems, supporting the varied input voltages found on different rail networks and substations. IoT-enabled DC-UPS power supplies round out the selection, offering N+1 redundancy support and remote monitoring for applications where continuous, uninterrupted power is non-negotiable, from signalling systems to control room infrastructure.\u003c\/p\u003e\n\n\u003cp\u003eExplore the featured models below, or browse the complete range for the full catalogue of railway and industrial power conversion products available through Powerbox, backed by local engineering support for specification, sourcing and integration queries across new builds and retrofit projects.\u003c\/p\u003e","products":[{"product_id":"premium-crs-60-series","title":"Premium CRS-60 Series DC\/DC Converter","description":"\u003cp\u003eThe Premium CRS-60 Series are railway-grade PWM DC\/DC converters providing 50–60W of isolated power conversion across five nominal input voltages (12, 24, 48, 72 and 110Vdc) and four output voltages (5, 12, 24 and 48Vdc).
