7796HC SPECIF ICATION SHEET

The AE Techron 7796HC amplifier is a
DC-enabled unit optimized for high­power, continuous operation into very­low-impedance loads. A single
7796HC has an output capability of up
to 200 amperes peak. If more current
is needed, up to four amplifiers can be
combined in parallel and operate as a
single system.

The 7796HC 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).

Performance

Frequency Response:

DC – 30 kHz +0.1 – 0.5 dB

Phase Response:

+/- 8.3 degrees (10 Hz – 10 kHz)

Unit to Unit Phase Error:

+/- 0.1 degrees at 60 Hz

Maximum Continuous Output Power:

2499 watts RMS

Output offset current:

Less than 10 milliamperes DC

Features

• 40 mSec pulses of up to 157 amperes peak into a 0.25-ohm
load.

• System output of over 600 amperes maximum are possible with
multiple, interconnected am plif iers .

• Frequency bandwidth of DC to 75 kHz at rated power, DC to
150 kHz at reduced power.

• Rugged chassis for stand-alone or rack mounted operation. No
additional power supplies are required.

• Protection circuitry protects the AE Techron 7796HC from input
overloads, improper output connection (including shorted and
improper loads), over-temperature, over-current, and supply
voltages that are too high or low.

• Shipped ready to operate from 208-volt (±10%) three-phase AC
mains. NOTE: 400 VAC version not available.
