ACS-250-100W (150 kHz to 250 MHz)

Power Amplifiers for EMC Immunity Testing

The ACS-250-100W is a broadband RF power amplifier designed for IEC 61000-4-6 conducted immunity testing and a wide range of EMC applications. Operating from 150 kHz to 250 MHz, it delivers 100 W of output power with 50 dB gain and maintains clean, distortion-free performance without compression up to full rated output.

The amplifier supports AM, FM, and pulse modulation, features automatic safety shutoff for load mismatch protection, and includes a front-panel LCD for monitoring key operating parameters. Housed in a rugged 4U rack-mount chassis with forced-air cooling and USB remote control capability, the ACS-250-100W provides a reliable, high-performance solution for EMC compliance and pre-compliance testing environments.
