P-DUKE has announced another ultra-wide input voltage range DC/DC converter, the RCD10U, to its 10W to 200W DC/DC converter series with a 12:1 input voltage range. This DC/DC converter series provides high performance and high reliability for any railway/ rolling stock and harsh industrial application. The compact 1″x1″ industrial standard package delivers up to 10W output power and features 8:1 and 12:1 ultra-wide input voltage ranges of 9-75VDC and 14-160VDC, which simplify the design of the system’s power stage. Using just one DC/DC converter model for various supply voltages (24, 28, 36, 48, 72, 96, 110VDC) in different regions avoids multiple input voltage models in the warehouse.
The patented enhanced Hold-Up Function is designed to simplify the design of supply interruptions and changeovers as per EN 50155. The BUS pin of the RCD10U provides a stable and fixed charging voltage which allows the usage of just one Hold-Up capacitor for any input voltages and additionally, reduces the in-rush current during the start-up phase.

This series includes single output and dual output models with 3.3, 5, 5.1, 12, 15, 24, ±5, ±12, ±15VDC. It has various self-protection functions i.e., over-current protection, output short-circuit protection, output over-voltage protection, adjustable input under-voltage lockout and over-temperature protection. These converters achieve the operating temperature class OT4 and the extended operating temperatures ST1, as per EN 50155 standard. The RCD10U series is certified according to IEC/EN/UL 62368-1, EN 50155, and EN 45545-2 standards (pending). Additionally, shock and vibration levels are compliant with EN 61373 and MIL-STD-810F. With an operating altitude of up to 5000 meters, a wide operating ambient temperature of -40°C to +105°C, and the 12:1 input voltage range, these converters are especially suitable for any ruggedized, high-reliable application such as rolling stocks, transportation, and construction machinery in harsh industrial environments.
