Series ELR 5000 6U 320W up to 3200W

This series EA-ELR 5000 was designed to configure a multi-channel electronic DC load. In a rack for 19” sys-tems, up to ten DC load units with 320 W nominal power each can be installed. The modular units operate separately from each other, but require the rack as it contains the energy recovering DC-AC inverter. The modules are also extendable. Parallel connection on the DC inputs of the module is possible. The load mod-ules come in two voltage variants, 80 V and 200 V, and incorporate the common regulation modes constant voltage (CV), constant current (CC) and constant power (CP).

The energy recovery function inverts the supplied DC energy into a synchronous sine current and feeds it back into the local grid. This reduces the usual heat dissipation to a minimum and saves energy costs at the same time. The color TFT touch panel offers an intuitive kind of manual operation.

Equipped with an Ethernet port by default, the load units can be easily integrated into a network of LAN devices with a standard LAN switch, which is also available as accessory (Netgear, 1U, 19”). External con-trol is possible via an included Windows software or via custom applications created in LabView or other IDEs. The commonly known communication protocols SCPI and ModBus RTU are supported.
