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

Description

AE Techron 7782HF/HC Power Amplifier DC – 200 kHz 4kW is a DC-enabled unit optimized for high-power, continuous operation into very-low-impedance loads. A single 7782HF/HC can output a 40 mSec pulse with up to 150 amperes peak current. If more current is needed, up to four amplifiers can be combined in parallel and operate as a single system.

The 7782HF/HC can operate in either voltage or current mode. It provides very low noise and fast slew rates, and can safely drive a wide range of resistive, inductive loads.

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)
