Programmable AC Source 2KVA, this is the lowest cost programmable AC source. The Chroma 6420 Programmable AC Source 2KVA is designed for bench or ATE applications require line and frequency variations. The Chroma 6420 Programmable AC Source 2KVA has 0-300VAC/45-1 KHz/ up to 9KVA single and three phase. Chroma's 6400 Series is designed for bench top and automated system applications requiring variations in line voltages and frequencies are a low cost. The 6400 series includes two voltage ranges (0-150VAC & 0-300VAC) as well as precision read backs for RMS voltage, RMS current, true power, frequency, and peak current crest factor
