The RHKW/RHDW series are high-performance DC/DC converters with 3000 VAC reinforced isolation and 4.5 mm clearance/creeping distances for safety-critical applications. The next-generation, board-mountable DC/DC converters have been designed especially for demanding, ruggedised railway and industrial applications.

The series consist of 3–40 W DC/DC converters with single and dual output models in a DIP24 (3–10 W) or 2″ x 1″ (40 W) package. They have an input range of 36–160 VDC and are equipped with circuits for over/undervoltage protection, as well as over-current, short-circuit and over-temperature protection.

The high-density power converters are realised by using a patented transformer design, which lets the converters perform with an efficiency of up to 90%. The high dielectric strength plastic housing with high-thermal conductivity, comparable with metal casing, performs the isolation between input case output and allows for an operating temperature range of -40 to +105°C.

The converters have been equipped with internal EMI circuits — IEC/EN 55032 Class A and IEC/EN 50121-3-2 — to simplify the design for saving space on PCBs. This series is certified according to IEC/EN/UL 62368-1, EN 50155 and EN 45545-2. Additionally, shock and vibration are compliant with EN 61373 and MIL-STD-810F.

An operating altitude of up to 5000 m, a wide operating ambient temperature and a 36–160 VDC input range make the converters suitable for any safety-critical application where a SELV output is mandatory. Examples are bus voltages of 72, 96 or 110 VDC which need a safety barrier on the secondary side in rolling stocks, in transportation or in harsh industrial environments.
