Intepro’s line of regenerative DC Load products offer all the necessary features of today’s electronic loads, plus the added benefit of energy recovery to mains. Regenerative technology converts the supplied energy into a synchronous sine current and feeds it back into the local or public grid. This reduces the usual heat dissipation to a minimum and saves energy costs at the same time. This feature also offers a cost-effective alternative to expensive cooling systems used by conventional air- and water-cooled loads to dissipate energy as heat. Over time these regenerating products easily pay for themselves.

Intepro offers two versions of the Multi-Channel DC Load products and three of the Single Channel products. This family of DC Load products will handle up to 1500Vdc and up to 10.5kW of power. Two of the Single Channel models can be paralleled for even higher power levels. In fact, There are three models that have the Function Generator capability in order to replicate the most unique loading applications.

The most important feature of certain of these electronic DC load products is that the AC input, i.e. grid connection, is also used as output for the recovery of the supplied DC energy, which will be converted with an efficiency of approximately 93%. This way of energy recovery helps to lower energy costs and avoids expensive cooling systems, such as required for conventional electronic loads which convert the DC input energy into heat.
