7212 FOUR-QUADRANT POWER AMPLIFIER

7224 amplifier

 

Up to 113 Vrms potential at up to 4A; provides needed voltage for grid simulation or driving real-world objects.

The 7212 is a 4-quadrant power amplifier that was created to meet the exacting requirements of the power utility industry. It features a low noise floor, very fast slew rate and a 113V RMS potential. The 7212 can be combined to form a 3-phase Y voltage source, and has a wide range of field-configurable options. The 7212 with "P" option offers even lower output offset, DC drift and better gain linearity than the base unit.

Features:

  • Low noise – Noise floor of only 300 µV.
  • Phase stability – DC – 250 kHz bandwidth design minimizes phase shift of system output when reproducing the most rapid fault events.
  • 113 volt RMS potential at up to 4 amps – Provides needed voltage for simulation or when driving real world objects.
  • Very fast slew rate – 75V/µS gives the 7212 the ability to reproduce events only a few µS in duration.
  • Robust design – Very forgiving of common failure events, dead short, etc.
  • Optional high precision “P” version – A special higher accuracy, lower DC drift version is available for ultra-critical applications.
