Emparro67: Power Supply in the Field

Emparro67 power supply units are specially designed for applications outside the control cabinet. They withstand extreme environmental conditions and can be installed directly in the field, next to the loads. This makes them the ideal solution for decentralized installation concepts. Power loss is reduced to a minimum.

Such losses occur if power supply units are used with an output voltage of 24 VDC and the power is supplied to the loads with cables that are too long. By using Emparro67, the voltage is converted from 230 VAC to 24 VDC directly at the load. By doing this, the power loss is much lower and the energy costs are reduced.

Installing the power supply units outside the cabinet by using Emparro67 offers many more benefits: Smaller cabinets can be used, in some applications it may even be possible to completely get rid of the cabinets.

To make power supply units suitable for extreme environmental conditions, their components have to be protected from mechanical stress. That's why Emparro67's compact and rugged metal housing is fully potted and IP67 sealed. Dirt, humidity, and cooling lubricants cannot damage the components. This makes Emparro67 a universal unit for many different applications.

The single phase Emparro power supplies for IP20 applications have proven how energy efficient they are in various applications. Their reliable active PFC technology is also used in Emparro67. This way, up to 92.4% of the energy applied can be used.

Emparro67 converts almost no energy into heat, therefore it's always possible to touch the units, even when under full load and in high ambient temperatures.   The units work reliably up to ambient temperatures of 85°C, which is exceptional for power supplies.

Another excellent feature of Emparro67 is its power boost function. The units supply up to 150% of the nominal current for a period of up to 4 seconds. High capacitive loads can be started without causing voltage drops. An integrated primary fuse provides additional protection of the unit.

Emparro67 is available in two models with output current of 4 and 8 A - so you can select the model corresponding to the number of loads connected.
