OLFER Electronics presents the new RQB40W12 series 40W DC/DC converters in a quarter-brick format (12:1 and 14-160V DC) and the RQB150W3 series 150W DC/DC converters (3:1 and 66-160V DC) for railway applications, meeting a wider range of power requirements.
Key features of these converters include: a wide input range covering the most common voltages used in railway applications (24/36/48/72/96/110V DC), a wide operating temperature range of -40°C to +90°C, compatibility with external capacitors for 10-30ms hold-up time, high isolation voltages (2KV AC/3KV AC), multiple protection features, and much more.
The RQB40W12 and RQB150W3 models are suitable for railways, trams, buses, information technology equipment, industrial automation, communications, DC UPS systems, battery voltage regulation and equipment requiring reinforced insulation levels.
