Programmable AC Power Sources for Verification & Automated Testing
Global electrical grids present diverse voltage levels, frequency fluctuations, and unexpected power disturbances. Chroma programmable AC power sources enable R&D engineers, quality assurance teams, and automated test system (ATE) integrators to precisely simulate real-world grid conditions under controlled laboratory environments. From basic single-phase power delivery to high-power 3-phase regenerative grid emulation, our AC power supplies deliver pure, low-distortion sine waves alongside advanced power line disturbance (PLD) simulation capabilities.

Key Capabilities of Chroma AC Power Equipment
Designed to meet international compliance standards (IEC 61000-4-11, IEC 61000-4-13, MIL-STD-704, DO-160), Chroma AC supplies deliver advanced control features necessary for severe line disturbance emulation.
Power Line Disturbance (PLD) Simulation
Engineers can generate real-world voltage sags, momentary spikes, frequency drifts, step variations, and complete outages using programmable STEP, PULSE, and LIST modes for strict regulatory immunity validation.
Harmonic & Inter-Harmonic Synthesis
Incorporate up to 50th order voltage harmonics and inter-harmonics to emulate distorted grid power. Analyze unit under test (UUT) thermal performance, power factor, and operational stability under degraded inputs.
Energy-Saving 4-Quadrant Regeneration
Our 61800 series acts as both an AC power source and a regenerative load. Power absorbed during inverter or V2G testing is recycled back to the facility grid with over 90% efficiency, significantly cutting electricity and cooling costs.
Programmable Slew Rate & Phase Angle
Full control over voltage and frequency slew rates alongside start/end phase angles (0° to 360°). Essential for measuring inrush currents, transformer saturation, and peak input current stress.
Precision Measurement Capabilities
Built-in 16-bit measurement circuits display RMS voltage, RMS current, true power, apparent power, reactive power, power factor, current crest factor, and harmonic current spectrum without requiring external power meters.
Automated System (ATE) Integration
Equipped with standard RS-232, GPIB, USB, and Ethernet (LAN) interfaces supporting SCPI commands and LabVIEW drivers. Seamlessly integrates into automated test benches running Chroma PowerPro software.
