Load Container up to 5 MW


With the type series CONPOWER we offer extremely efficient load resistances up to 5 MW, which are ideal not only for tests on new generators, but also used in the area of controlled battery discharge. The load increments of JOVYLOAD CONPOWER can be switched current-depended in order to ensure sparing and regulated battery discharge.

The resistor units of these series are mounted into customary commercial sea containers together with their load units as well as the entire switchgear to control the load bank integrated into them. By its compact structural shape and its great degree of stability the use of standard containers ensures a good possibility of transport with the help of cranes or trucks and an easy access to the installations. The lateral ventilation of the containers allows stacking and sea transport (CSC authorisation optional).

The load bank used in the type series JOVYLOAD CONPOWER consists of independently installed load tunnels. In each case two load tunnels are arranged one above the other with further load tunnels connected adjacent to them depending on the desired power performance.


The use of the standard container offers the following advantages:
