7780RLY POWER AMPLIFIER

7780RLY was created to meet the demanding requirements of the power utility industry. With an output capability of 106 A rms (150A 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.
