Murrelektronik presents the new power supply unit named Emparro. The combination of the Power Boost function with a power limiter output allows large loads to be started easily. The unit's efficiency rating is up to 95%, which means that only 5% of the energy remains unused. Because of the low power loss, the power supply generates less heat. The new product offers Power Boost, providing up to 150% more power for up to 4 seconds. With this function users can start higher loads and capacities without requiring a second power supply unit. In the event of short-circuits or overload, the unit's output voltage is controlled with a constant current. It is limited to 100% of the nominal current (or to 150% in Power boost mode). This power limiter function protects the power supply unit reliably from damages caused by overloads and is an important aid when starting up. The new power supply units feature a wide input voltage range from 85 to 265 V AC (90 to 250 V DC). It is available in seven different models, with output voltages of 12, 24 and 48 V. The metal housing ensures optimum EMC characteristics. The units work reliably because of a wide optimal temperature range from -25 to +60° and continuous high-performance without derating. An alarm contact enables remote diagnostics: It signalizes short-circuits, overloads and excessive temperatures.
