Chroma 61607 Programmable AC Power Source

Overview

The Chroma 61607 is a 3 kVA programmable AC power source with enhanced capabilities for both single-phase and three-phase testing applications. Operating from DC to 2 kHz with output voltages from 0 to 350V, it delivers advanced measurement and harmonic synthesis capabilities. Using state-of-the-art PWM technology, it generates pure sine waveforms with less than 0.3% distortion at 50/60 Hz, making it ideal for complex testing scenarios in commercial, power electronics, avionics, military, and regulatory environments.
