The Chroma 61845 Regenerative Grid Simulator is an advanced, full 4-quadrant, fully regenerative AC power source, meticulously engineered for a wide range of electrical product testing. Ideal for evaluating home appliances, industrial electronics, and testing PV inverters and online UPS systems, this simulator offers a versatile programmable input source that ensures seamless power sourcing and sinking from the Unit Under Test (UUT). In scenarios where the UUT generates excess current, a specialized detection circuit efficiently recycles this power back to the grid.
This simulator excels in smart grid and electric vehicle (EV) testing applications, including Vehicle to Grid (V2G) and Energy Storage System (ESS) evaluations. Its extensive feature set extends beyond product development in R&D environments; it is exceptionally useful for design validation, quality assurance, and throughout various production stages. Leveraging cutting-edge digital control technology, the Chroma 61845 delivers output voltages of up to 300 VAC across a frequency range of 30 Hz to 100 Hz, with a unique AC+DC functionality for applications requiring a DC offset bias.
This remarkable grid simulator not only provides precise, stable AC voltage for standard applications but also simulates a variety of distorted voltage waveforms and transient conditions critical for comprehensive product validation testing. Users can take advantage of built-in programmable waveform functions such as LIST, STEP, and PULSE modes to achieve this. The STEP and PULSE functions allow single or continuous step changes in output voltage, while the LIST mode enhances versatility, enabling the creation of complex waveforms with up to 100 sequences. It efficiently meets immunity specification requirements, such as IEC 61000-4-11, for short interruptions and voltage drops.
Designed for maximum user flexibility, the SYNTHESIS function empowers users to generate periodic harmonic voltage waveforms of up to 40 orders, anchored on a fundamental frequency of 50/60Hz. Additionally, the INTERHARMONIC function facilitates frequency sweeps from 0.01Hz to 2400Hz, enabling precise identification of resonance points.
The Chroma 61845 also boasts advanced measurement capabilities, providing accurate readings of RMS voltage, RMS current, true power, power factor, and current crest factor, to name a few. Thanks to sophisticated DSP technology, this simulator can effortlessly mimic power line disturbances (PLD) utilizing LIST, PULSE, and STEP modes. With advanced waveform synthesis, it meets regulatory standards by programming various distorted harmonic waveforms. Control is seamless through multiple remote interfacing options including GPIB (IEEE488.2), RS-232, USB, and Ethernet.
