The UK rail network is under continuous improvement by the operators which creates certain demands on the type of DC DC power converters required. Especially critical is the requirement for suitably isolated units.
Relec Electronics is a specialist supplier of electronics solutions specifically selected and designed for applications in the Railway Industry. With over 38 years’ experience the company has a highly qualified engineering and QA team to ensure that the most suitable products are selected and can also offer customised design and manufacturing options to give greater flexibility to the range of solutions offered.
The company is pleased to announce the availability of a new DC DC converter from Mornsun, the URB1D-LMD-10/15/20WR3 series with improved isolation.
The units have a 40–160VDC ultra-wide input voltage with 2250VDC reinforced insulation meeting EN60950/EN50155 and are suitable for 72V, 96V and 110V railway electronic equipment such as monitoring equipment, air-conditioning control and information displays.
They provide an operating temperature of -40°C to +85°C and multiple protection (input under-voltage and output short-circuit, over-current, over-voltage protection).
The converters come in 2in x 1in standard package with two pin-out positions available. A2S (Chassis mounting) or A4S (DIN-Rail mounting) packages are also available, which have reverse voltage protection built in.
