The Chroma 61605 Programmable AC Power Source 4 kVA delivers pure, instrument grade AC power at very low cost. It is suitable for commercial, avionics, and military applications from bench-top testing to mass production. The 61605 generates very clean AC output with distortion less than 0.3% at 50/60Hz. With the state-of-the-art PWM technology and power factor correction circuit, the 61605 yields higher efficiency and delivers more output power. The 61605 is capable of delivering up to 6 times of peak current compared to its maximum rated current that makes it ideal for inrush current test.
