California Instruments OMNI 3-16

The California Instruments OMNI 3-16 is a programmable AC power source engineered for laboratory and industrial simulation of AC power conditions across single and three-phase configurations. The unit delivers 16 A output and integrates PC-based control software with high-speed data acquisition for compliance testing to international standards including IEC 61000-3-2, IEC 61000-3-12, IEC 61000-3-3, and IEC 61000-3-11. This platform supports harmonic analysis up to order 200 (10/12 kHz) and flicker characterization, making it suitable for power quality assessment, equipment immunity qualification, and harmonics distortion testing.
