7796HC
7796HC
AE Techron
Precision, DC-enabled Linear Power Amplifier
Up to 200 Ap Inrush Current, DC to 100+ kHz, Three-Phase
- Stable when driving a wide range of resistive, inductive or capacitive loads
- Field-selectable controlled-voltage or controlled-current operation
- Can be switched between rail supply modes to optimize for various load impedances
- Protection circuits guard against over/under voltage, over current, over temperature, and circulating ground currents
The 7796HC power amplifier offers up to 85 Ap continuous at 13.5 VDC, DC – 250 kHz small-signal bandwidth, and controlled-current or controlled-voltage modes of operation. The 7796HC can be used to simulate ripple noise, drop outs, surges and ground shift noise as required by a variety of standards for DC-powered electronics in the aviation and automotive industries.
A single 7796HC makes a very good choice for 13.5V DC-based power susceptibility test standards for high-current-draw EUTs (up to 85A).With configurations capable of up to 600Ap and the ability to both source and sink, the 7796HC is your best solution for high-current DC Conducted Immunity testing.
