Power Amplifier: 30 Hz to 300 kHz
- ▸ ARI-300K low-frequency power amplifier, 30 Hz–300 kHz — a low-frequency RF power amplifier for conducted and radiated susceptibility testing per MIL-STD-461 and RTCA DO-160.
- ▸ Up to 150 W into low-impedance loads — delivers up to 150 W into 1–2 Ω loads, 100 W into 4 Ω, and 50 W into 8 Ω, with ≤8% distortion.
- ▸ Extended 300 kHz upper frequency — the wider 30 Hz–300 kHz range covers more low-frequency susceptibility test requirements than 150 kHz-class amplifiers.
- ▸ Built for MIL-STD-461 CS101 and RS101 testing — supports conducted susceptibility (CS101) on power and signal lines and radiated susceptibility (RS101) magnetic field immunity, plus RTCA DO-160 Section 18.
- ▸ Precision performance with ±5° phase response — maintains ±5° phase accuracy up to 75 kHz and DC drift under ±1.5 mV after warm-up for stable test conditions.
- ▸ Robust over-temperature and over-current protection — built-in protection circuitry with LED fault indicators safeguards the amplifier during demanding test runs.
- ▸ Front-panel digital monitoring — displays internal temperature and bias current in real time; BNC input and dual 4 mm banana-jack outputs suit versatile lab setups.
- ▸ 3U rack-mount design with wide-range AC input and three-year warranty — operates on 100–250 VAC with forced-air cooling, sized for lab and system integration.
