Murrelektronik presents Emparro, a power supply unit with maximum efficiency and minimum power loss. The efficiencies achieved through the new design also reduce the heat generated in the unit increasing the life of the power supply.
Modern machine builders and machine users are focusing their attention on power consumption. Their power supply units focus on efficiency because energy is a precious commodity and unused machine energy increases costs.
Compared to power supplies with an efficiency rating of about 90% and a resulting power loss of 10%, Emparro reduces power loss by 50%. Because of Emparro’s lower power loss, the power supply unit generates less heat. This means less thermal stress for the individual components within the housing and increases Emparro’s lifetime. The same applies for the components installed near Emparro. Those units benefit from lower heat exposure than conventional, less efficient, power supplies and can help in the selection of more compact control cabinets. Thus, they last longer.
It’s not only efficiency that makes Emparro an advanced power supply unit:
Emparro supports startup: Emparro offers Power Boost, providing up to 50% more power for up to 4 seconds. With this Power Boost function you can start higher loads and capacities without requiring a second power supply unit.
Emparro optimizes overload behavior: In the event of short-circuits or overload, Emparro’s output voltage is controlled with a constant current. It is limited to 100% of the nominal current (or to 50% in Power Boost mode). This constant power function reliably protects the power supply unit from damages caused by overloads and is an important aid when starting up.
Emparro communicates: An alarm contacts is present on the Emparro circuit for you to take advantage of remote diagnostics: It signals short-circuits, overloads and high temperatures.
Emparro is stable: The all-metal frame ensures optimum EMC characteristics and the wide operating temperature range from -25 to +60°C ensures optimal performance without derating.
