Reliability was a high priority during development of the new 3-phase units. Achieving a remarkable MTBF of about 1,000,000 hours is possible because of high-quality components, a 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.
The up to 95% efficiency rating is another reason the Emparro 3-phase unit has such a long life span. The resulting power loss is very low which exposes the components to less thermal stress.
Integrated Reserved Power
Emparro 3-phase are designed in such a way that they can be operated with up to 20% overload in ambient temperatures of up to 45°C. The 5A models continuously supply 6A, 10A models 12A and 20A units 24A.
This offers two essential benefits. The first is that if additional loads have to be connected to a machine or a system, Emparro 3-phase offers the necessary reserve. The second is if the demand is close to the maximum of a power supply a larger power supply does not have to be used.
Emparro 3-phase also features 2 different boost functions: power boost and hyper boost. The Power Boost supplies 50% more power for up to 5 seconds while the Hyper Boost provides up to 400% more power for up to 20ms.
The Slimmest Power Supply Units on the Market
Emparro 3-phase power supplies are very compact: the 20A model fits in a 65mm wide housing. When compared to similar power supplies, this saves a lot of space in the cabinet.
The vibration resistant push-in terminals make installation tool free so connection maintenance becomes a thing of the past. While the integrated fuses help to reduce planning and wiring efforts.
