Chroma 61830 Regenerative Grid Simulator
RENT CHROMA 61830 - call for availability
The Chroma 61830 Regenerative Grid Simulator is an advanced 4-quadrant, fully regenerative AC power source specifically designed for the rigorous testing of electrical products, including home appliances and industrial electronics that require a programmable input source. This simulator is also tailored to simulate grid characteristics essential for testing photovoltaic (PV) inverters and online uninterruptible power supplies (UPSs). With the ability to function seamlessly as both a power source and sink, the 61830 supports a wide variety of applications. In situations where the unit under test (UUT) supplies current, an integrated detection circuit efficiently senses surplus power and recycles it back to the grid.
The 61830 is particularly well-suited for testing related to smart grids and electric vehicles (EVs), including Vehicle to Grid (V2G) and Energy Storage System (ESS) applications. Its extensive feature set is invaluable throughout the entire product development process, from research and development (R&D) to design verification and production stages. Thanks to cutting-edge digital control technology, the 61830 can deliver outputs of up to 300 VAC at frequencies ranging from 30 Hz to 100 Hz. For applications requiring a DC offset, the AC+DC function is readily available.
Not only does the 61830 provide clean and stable AC voltage for regular applications, but it is also capable of simulating a variety of distorted voltage waveforms and transient conditions necessary for comprehensive product validation. Its built-in programmable waveform functions—including LIST, STEP, and PULSE modes—enable users to perform both single and continuous voltage changes. The LIST mode allows for the creation of complex waveforms with up to 100 sequences, while voltage waveforms required for immunity specifications such as IEC 61000-4-11 can be easily simulated.
The SYNTHESIS function facilitates the creation of periodic harmonic voltage waveforms of up to 40 orders, based on a fundamental frequency of 50/60Hz. The INTERHARMONIC function allows for frequency sweeps from 0.01Hz to 2400Hz, assisting users in identifying resonance points. Additionally, the 61830 delivers precise measurements, including RMS voltage, RMS current, true power, power factor, and current crest factor, leveraging advanced digital signal processing (DSP) technology to simulate power line disturbances (PLD) using LIST, PULSE, and STEP modes.
Further enhancing its versatility, the 61830 features a waveform synthesis function for programming distorted harmonic waveforms, essential for compliance with various regulatory standards. Users can control the 61830 remotely via GPIB (IEEE488.2), RS-232, USB, and Ethernet interfaces.
