Description

Power Meets Precision in the 7548 Linear Amplifier

The 7548 Linear Amplifier is a high-performance, three-phase amplifier engineered to deliver massive peak and continuous power for industrial and test environments. Whether you’re conducting EMC testing, simulating pulsed loads, or driving demanding inductive applications, the 7548 stands out with its precision, rugged build, and flexibility.

Exceptional Peak and Continuous Output Capabilities

This amplifier provides up to 12,000 watts peak power for short 40 ms bursts and delivers 5,500 watts continuous power into a 1-ohm load. A single unit can produce up to 100 amperes peak and 195 volts peak, while multiple interconnected amplifiers can scale the output to 800 Vp or 170 Ap, enabling large-system simulation with ease.

Its frequency response spans DC to 100 kHz, with a rated power bandwidth up to 50 kHz. A slew rate greater than 35 V/μs ensures sharp and accurate waveform reproduction. The amplifier’s low residual noise, minimal DC drift, and ultra-low output offset make it ideal for sensitive and high-speed test applications.

Voltage and Current Control with Built-in Protection

The 7548 offers field-selectable voltage or current control, giving users flexibility to adapt to various load types and test protocols. Built-in protection systems monitor over-voltage, over-current, over-temperature, and circulating ground currents to safeguard both the amplifier and connected equipment during rigorous testing.

Designed for Demanding Applications

From MRI gradient coil simulation to MIL-STD-704F compliance, the 7548 supports a wide range of advanced applications. Its ability to provide both continuous and burst power makes it a preferred choice for labs requiring three-phase simulation or high-current pulsed operation. Additionally, its intuitive LCD and LED panel delivers real-time feedback on voltage, current, and system status, helping users manage and adjust performance with confidence.
