7796HF DC-100kHz AC Amplifier
APPLICATION

The 7796HF is an extended frequency version of the 7796 amplifier. The 7796HF has a power bandwith of 100kHz. The amplifier can drive a wide range of loads from less than 1ohm to open circuit. At lower voltages it is capable of significant ouput past 200kHz. The 7796HF works well with continuous or pulse test signals.

FEATURES

• 60VuSec Slew rate*, multiple units can be connected in series for slew rates in excess of 100VuSec*
• Power bandwidth of DC - 100kHz, DC - 200kHz available at lower voltages
• Rugged chassis for stand-alone benchtop or rack-mounted operation
• Protection circuitry hardens the 7796HF to input overloads, improper output connection (including shorted and improper loads), over-temperature, over-current and incorrect supply voltage
• Shipped ready to operate from 208 volt, three-phase AC mains. Operation from 380 or 415 volt AC mains are available

POWER BANDWIDTH COMPARISION
The 7796HF provides nearly double the voltage at 100kHz when compared to the standard 7796.

Amplifiers connected to 4ohm, 3uH load.

Both amplifiers operated with their power supply locked low.

The 7796 and 7796HF amplifiers are capable of higher voltages below 80kHz depending on load.

The 7796HF is especially effective when driving low impedance loads at frequencies over 50kHz and below 200kHz.
INDICATORS AND CONTROLS

• Front panel LEDs indicate ready, standby and fault conditions in output stage.
• Front panel display lists type of fault condition and gives suggested corrective action.
• Front panel soft touch switch to place amplifier in run or standby mode.
• Front Panel is user configurable for up to four simultaneous displays reporting one, two or all four of the following: Voltage Peak, Voltage RMS, Current Peak, and Current RMS.
