We use three high-performance, programmable 3-phase AC power sources for testing:

• Ametek MX45-3PI-480-HV
• California Instruments Tahoe TA0045A1E1-01A00A
• Chroma 61845

Each of these units is a 45 kVA voltage source capable of delivering stable and programmable AC power. These sources are used to test a wide range of input conditions across all product types, including 115V and 230V EU internal non-redundant power supplies, as well as 230V, 277V/480V, and 380V DC internal redundant systems. They support full compliance testing by simulating global input voltages and power conditions.
