Chroma 61860 Regenerative Grid Simulator

Overview

The Chroma 61860 is a 60kVA, four-quadrant, fully regenerative AC power source designed for comprehensive electrical product testing. It supports seamless power sourcing and sinking, with built-in energy recovery to recycle excess power back to the grid, making it ideal for applications requiring bidirectional power flow.

Key Features

• Full 4-quadrant, fully regenerative operation up to 100% of output current rating
• Output voltage: 0-300V with AC+DC offset capability for DC bias applications
• Output frequency: DC to 100Hz (30Hz-100Hz standard range)
• Programmable waveform functions: LIST (up to 100 sequences), STEP, and PULSE modes for power line disturbance simulation
• Harmonics and inter-harmonics waveform synthesizer (up to 40 harmonic orders)
• Voltage transient simulation including dips, short interruptions, and voltage variations per IEC 61000-4-11
• Comprehensive measurements: RMS voltage/current, true power, power factor, current crest factor, and harmonic analysis
• Programmable slew rate, voltage and current limits, turn-on/off phase angle control
• Multiple remote interfaces: GPIB (IEEE 488.2), RS-232, USB, and Ethernet
• User-selectable single-phase or three-phase output with parallel output capability for higher power applications
