Regenerative AC load voltage range

AC / DC Load with Constant Power Voltage Range

Accurately simulate the power grid with seamless transition of voltage ranges. A single constant power voltage range for both higher current at lower voltage and higher voltages at lower currents eliminating the need to switch between voltage ranges. This prevents potential disruptions in output power.

  • Wide operating envelope
  • More current at lower voltage
  • Test broad range of power
  • Seamless transition of input power
AGX RGS RLS Highest Current Availability

Highest Current Availability for AC Load Simulation

The RLS Regenerative Load Simulator provides a broader range of current eliminating the risk of over or under sizing the power source. This reduces the need for additional capital investment. The diagram to the right illustrates the RLS’s capability to provide 20% more current from 120V to 200V when compared to a typical unit that maxes out at 35A/phase.

  • More current at lower voltage
  • No over or undersizing the load
  • Reduce the need for additional capital
4 Quadrant AC DC Regenerative Load - Lagging Current

Full 4 Quadrant Operation for Leading & Lagging Power Flows

Fully test AC & DC Power with Bidirectional, 4 quadrant operation. The programmable AC or DC electronic load has 4-Quadrant capability so both true and apparent power can be drawn with programmable control over power factor, current crest factor, current waveshape etc.

Several Emulation Modes for Simulation AC & DC Loads

Regenerative AC/DC Electronic Load capability with both AC and DC operating modes pushes the boundaries of your test environment. Simulate linear and non-linear loads (including rectified), inductive and capacitive loads.

  • AC Modes: Constant Current, Constant Power & Apparent Power, Constant Resistance, CR+CC, CC / CS Rectifier Mode 1ø & 3ø
  • DC Modes: Constant Current, Constant Power, Constant Resistance, Constant Voltage, CR+CC
Flexible AC DC Input Configurations

Most Flexible Input Configuration for AC/DC Load Simulation

Simultaneous AC and DC load operation of modes per phase(or channel), and the automatic switching of input modes provides test engineers with a unique capability and the highest degree of flexibility. AC, DC input configurations are available in single, split, three phase and multi-channels with optional isolated neutrals in AC and DC.

  • AC, DC configurations
  • Simultaneously test AC and DC,on separate phases
  • Full galvanic isolation from facility AC input to output and between output phases/channels also protects the user and the UUT.
