The 7782HF is an extended frequency verison of the 7782. The 7782HF is best suited for controlled voltage applications that require higher voltages between 50kHz - 100kHz. The 7782HF is ideal for situations like DO-160 testing that require high current from DC - 20kHz and DC - 150kHz power bandwidth.

At frequencies below 20kHz, the 7782HF can provide 40mSec bursts of 180 amps peak. At frequencies up to 100kHz, the 7782HF can provide up to 40 volts.

The 7782HF can operate in either voltage or current operation modes and is DC-coupled.

• Over 4,000 watts peak output; 2858 watts RMS into 2ohm load
• 40mSec pulses of up to 150 amperes peak into 1ohm load
• Can be connected (up to 4 units) in series or parallel mode with additional 7782HF units
• Utilizes Bi-LevelTM Smart Power Supply, able to generate both high voltage & high current with less heat than with a standard single level power supply
• Frequency bandwidth of DC - 50kHz at rated power into 8ohm, DC - 200kHz at reduced power
• Rugged chassis for stand-alone benchtop or rack-mounted operation; no additional power supply required
• Protection circuitry protects the 7782HF from input overloads, improper output connection (including shorted & improper loads), over-temperature, over-current and under/over supply voltages
• Shipped ready to operate from 208V three-phase AC mains. Operation from 380V, 400V, 415V AC mains available
