Description


Tekbox TBDCA1 – DC to 10 MHz, 150 W DC-Coupled Power Amplifier

The Tekbox TBDCA1 is a low-output-impedance, DC-coupled power amplifier designed to extend the voltage, current and power capability of an arbitrary waveform generator. It delivers up to 150 W continuous output power, with a 3 dB bandwidth from DC to 3 MHz and usable operation up to 10 MHz. A maximum 56 Vpp output, 10 A RMS continuous current capability and switchable gain from 0 dB to 40 dB make it suitable for driving demanding low-impedance loads and reproducing fast automotive and EMC test waveforms.

The TBDCA1 supports AC- or DC-coupled operation and selectable 50 ohm or high-impedance input termination. Its adjustable +/-25 V DC offset allows it to act as a voltage-controlled power source in suitable low-voltage applications, while dedicated voltage and current monitor outputs simplify measurement at the load. Adjustable current limiting and front-panel status indication help protect both the amplifier and the connected test setup.
