ELR 9000: Are you also looking for an Electronic Load with Energy Recovery (Mains Back-Feed) Featured

The 14 models of series ELR 9000 offer a big variety of electronic load with energy recovery (Mains Back-Feed) feature. Voltage between 0...80V and 0...1500V, as well as currents between 0...22A and 0...510A at power ratings of 0...3500W, 0...7000W or 0...10500W are available.

The 19" enclosure in only 3U size makes it possible to build high power cabinets of up to 105kW total power or even more, with a minimum of effort.

The standard integrated energy recovery feature presents some interesting features compared to common DC loads:

• The supplied DC energy is converted to AC with approx. 95% efficiency and fed back to the local or public grid --> this saves energy costs
• Extensive cooling or exhaust systems can be omitted, because the heat emission is reduced to a minimum
• Significantly reduced audible noise
• Reduced device height

ELR 9000
Of course, the devices include all common features of modern electronic DC loads. For example, all models offer the four regulation modes constant voltage (CV), constant current (CC), constant power (CP) and constant resistance (CR). The fast, digital, FPGA based control circuit also provides a set of new functionality: True function generator with square, sine, saw tooth or arbitrary curves, each applicable to one of the set values U, I Simulation of non-linear internal resistances A loadable value table with 4096 points that is embedded in realtime into the control circuit

Interfaces Modules / Connections
For remote control via PC and integration into industrial networks such as CAN or Profibus, all models can be used with a selection of pluggable interface modules for CANopen, Profibus, ProfiNet, RS232, ModBusTCP, DeviceNet or Ethernet, besides the integrated USB interface. Another new feature is the USB host interface on the front, which enables the user to load/save so-called arbitrary functions and user profiles from USB flash drives.

Touch Panel
Handling and adjustment, as well as setup are simplified via the new touch panel. The big graphics display provides an overview of set values, actual values and device condition at a glance. Two additional rotary knobs are used to fastly and accurately adjust set values or settings in the setup.
