Product Overview

RENT CHROMA 61860 - call for availability

The Chroma 61860 Regenerative Grid Simulator is a full 4-quadrant, fully regenerative, AC power source designed for common electrical product testing such as home appliances, and industrial electronics needing a programmable input source. The 61860 is also designed to simulate grid characteristics for testing PV inverters and on-line UPSs. Power can be both sink and source from the UUT seamlessly to support a multitude of applications. In cases where the UUT sources current, a detection circuit will sense the excess power and recycle it back to the grid.

The 61860 Grid Simulator is also ideal for smart grid and EV related test applications such as Vehicle to Grid (V2G) and Energy Storage System (ESS) testing. The 61860 regenerative grid simulator's extensive feature set is not limited solely to product development during R&D, it is also valuable during design and quality verification as well as throughout various production stages. Using state of the-art digital control technology the 61860 can deliver up to 300 VAC at output frequencies ranging from 30 Hz to 100 Hz. The AC+DC feature allows for applications that require a DC offset bias.

In addition to supplying clean, precise and stable AC voltage for regular applications, the 61860 is capable of simulating various types of distorted voltage waveforms and transient conditions required by product validation testing. These are accomplished as shown below using built-in programmable waveform functions such as LIST, STEP and PULSE modes. The STEP and PUSLE functions allow users to perform single or continuous step changes of output voltage. LIST mode is a more versatile function, and allows users to compose complex waveforms of up to 100 sequences. Voltage waveforms required by immunity specifications such as IEC 61000-4-11 (short interruption and voltage dropout) can easily be achieved by the 61860 Regenerative Grid Simulator.

The SYNTHESIS function allows users to create periodic harmonic voltage waveforms of up to 40 orders based on a 50/60Hz fundamental frequency. The INTERHARMONIC function allows users to perform frequency sweeps ranging from 0.01Hz to 2400Hz on top of the 50/60Hz fundamental frequency. This special function assists users in locating the resonance points.

The 61860 is also able to provide precision measurements such as RMS voltage, RMS current, true power, power factor, current crest factor and many others. By applying advanced DSP technology, the Chroma 61860 can easily simulate power line disturbance (PLD) using LIST, PULSE and STEP modes. Additional features such as the waveform synthesis function allows users to program various distorted harmonic waveforms which are required by some regulatory standards. GPIB (IEEE488.2), RS-232, USB and Ethernet interface are available to control the 61860 grid simulator remotely.

Key specifications of the Chroma 61860 include:

  • Power Rating: 60kVA
