B&R
More space in the switch cabinet
The Acopos P3 servo amplifier from B&R is also available with a through-hole cooler or cold plate cooling. According to the manufacturer, these new cooling variants allow up to 60% of the heat loss to be dissipated into the ambient air outside the control cabinet.
This means that the control cabinet can be built much more compactly, as significantly fewer fans and air conditioning units are required or, ideally, are not needed at all. The cooling variants are suitable for any number of axes in all power ranges. As fans and air conditioning units that draw in air from outside are no longer required, significantly less dust enters the enclosure and maintenance work such as filter replacement is considerably reduced. As a result, the number of stops of the entire machine is reduced.
In the cooling method with a through-hole cooler, a heat sink dissipates the heat loss directly to the ambient air outside the enclosure. The heat sink has an IP64 protection rating and, according to B&R, complies with the EN 60529 and UL 50 Type 12 standards. The fan installed in the through-hole cooler has an IP54 protection rating. The cold plate method uses a water-cooled plate for cooling. The resulting heat loss from the appliances is almost completely dissipated to the cooling medium. A machine's own cooling circuit is required for cold plate installation.
