Power Supply – Emparro® 3~ – Murrelektronik

Murrelektronik’s Emparro family has a new member. The newly developed Emparro 3-phase power supplies for 24V applications are important components in quality power management systems. They are extremely reliable, extraordinarily efficient and they don’t require much space in the cabinet.
Reliable power supplies are an essential component to ensure maximum availability of machines and systems. Therefore, reliability was a high priority during development of these new 3-phase units.

Achieving this MTBF is possible because of our high-quality components, the modern and slim circuit board design and the processor-controlled electronics.
An integrated gas discharge valve protects the power supply from interfering pulses up to 6kV. Therefore, overvoltage coming from the mains, EMC interference (as caused by frequency converters) or contact bounces cannot cause any damage.

Emparro 3~ 40 A continuously monitors parameters like temperature, load or number of starts. The unit generates a message when it‘s time to be replaced. Replacement can be scheduled for the next service interval. This reduces downtime.
Emparro 3-phase has such a long life span because of its efficiency rating of up to 95%. The resulting power loss is very low which exposes the components to less thermal stress.
