AE Techron 7782HF Power Amplifier DC – 200 kHz 4kW For DO-160 Testing

Description

AE Techron 7782HF Power Amplifier DC – 200 kHz 4kW is a DC-enabled, extended frequency unit best suited for controlled voltage applications that require voltages between 50 kHz to 100 kHz. At frequencies below 20 kHz, the 7782HF can provide 40mSec bursts of 180 amps peak. At frequencies up to 100 kHz, the 7782HF can provide up to 40 volts.

The 7782HF can operate in either voltage or current operation modes. It is ideal for situations like DO-160 testing that require high current from DC to 20 kHz and DC to 150 kHz power bandwidth.

Typical use includes as a power source for EMC testing in applications that require both continuous AC or DC signals and significant short term (burst) signals (DO-160, MIL 461, and MIL 704).

Features

  • 7782HF provides over 4,000 watts peak output; 2,858 watts RMS into a 2-ohm load
  • 7782HF/HC delivers 40 mSec pulses of up to 150 amperes peak into a 1-ohm load
  • System output of 800 volts and 70 amperes maximum are possible with multiple, interconnected amplifiers
  • 7782HF provides a frequency bandwidth of DC to 50 kHz at rated power into 8 ohms; DC to 200 kHz at reduced power
  • Rugged chassis for stand-alone or rack mounted operation. No additional power supplies are required
  • Protection circuitry protects against input overloads, improper output connection (including shorted and improper loads), overtemperature, over-current, and supply voltages that are too high or low
  • Optional “P” versions offer precision control of output offset, DC drift and gain linearity
  • Shipped ready to operate from 208-volt (±10%) three-phase AC mains. Operation from 400-volt (±10%) An AC main is available on request (7782HF version only)
