7780RLY POWER AMPLIFIER

7780RLY was created to meet the demanding requirements of the power utility industry. With an output capability of 200A peak, the 7780RLY is powerful enough to put protection relays, fuses and other critical components through a full range of tests.

The low noise floor, low distortion & minimal phase error of the 7780RLY make it the ideal amplifier for power grid modeling.

FEATURES

  • High compliance voltage allows the 7780RLY to drive electromechanical relays directly.
  • Maintains phase accuracy for any load from a dead short to 0.25ohms.
  • Front panel indicators for rapid assessment of amplifier status.
  • Designed to survive input overloads, continuous operation under demanding conditions & improper output conditions - including improper loads.
  • Shipped ready to operate from 208 volt 3-phase AC mains. 240, 380 or 415 volt AC mains operation available upon request.
  • Installs into a standard 19 inch rack or stands alone for bench top operation.
  • Backed with AE Techron's application engineering, service facilities, complete technical information and a 1-year warranty.

INDICATORS AND CONTROLS

  • Front panel LEDs indicate power, standby, high AC mains, high temperature, signal overload and faulty output stage.
  • Front panel slide switch to place amplifier in run or standby.
  • Front panel slide switch to reset indicator LEDs.
