Feb 2008 - Slim MiniLine Power Supplies with 15W Output Power
For low-power requirements, three new units have been added to the MiniLine DIN-rail power supply family. With a nominal width of only 22.5 mm, three different output voltages are available; ML15.051 (5V), ML15.121 (12-15V) and ML15.241 (24-28V). Despite the compact construction, all units have an universal wide input voltage of 85 to 264Vac and deliver the full 15W output power over the typical MiniLine temperature range of -10degC to +60degC. Operation up to +70degC is also possible at slightly reduced output power. The units have a plastic housing and can be operated with or without protective earth (Ground) on the input side. The protective earth is not required for safety but does improve the electromagnetic immunity well above the minimum standards. In the development of the new ML15 series, cost effectiveness was an important aspect in the design. To optimize this, deviations from the standard MiniLine specifications occurred. For example, the spring-clamp terminals have been replaced with screw terminals allowing for larger wire cross-sections. The new terminals allow stranded wires up to 4mm2 or multiple wires with smaller cross-section on each connection point. The new 15W power supplies supplement the MiniLine family and provides the user further savings of space and price performance improvements.
