Regenerative Grid Simulators 9kVA-15kVA
Grid Simulators
Chroma 61800 3U high series of regenerative grid simulators include three models with power ratings of 9kVA, 12kVA, and 15kVA and include single phase and 3-phase operation. With output voltage ranges up to 350VLN and 606VLL, each model can achieve 700VLN by a single phase 3-wire setup. Users are able to increase output power by configuring up to three units in parallel.
Chroma 61809/61812/61815 regenerative grid simulators provide a complete energy-saving solution. The power generated by the DUT during the test can be easily fed back to the grid, rather than dissipated as heat, which protects the environment and lowers the cost of operation. With this capability, the 61809/61812/61815 models can be applied to applications in green energy products, such as PV inverters, energy storage systems (ESS), power conditioning systems (PCS), micro grids, power hardware-in-the-loop (PHIL), electric vehicle power supply equipment (EVSE), on-board charger (OBC) and bidirectional on-board charger (BOBC), etc.
For regulatory testing, 61809/61812/61815 models can be applied to IEC 61000-3-2/-3- 3/-3-11/-3-12 (international regulations for AC voltage testing), IEEE 1547/IEC 62116 (international regulations related to green power generation), electric vehicle to grid (V2G) testing, electric vehicle to load (V2L) testing, electric vehicle to home (V2H) testing, energy storage system (ESS) testing.
By using full digital control technology, these models provide a maximum 350VLN output voltage and 30Hz to 100Hz output frequency. The total harmonic distortion rate is less than 0.5% at full load and 50Hz/60Hz output frequency. In addition to AC output, a DC output mode and AC plus DC output mode is included which can be expanded to DC test and AC test with DC bias voltage. The current output capability can provide 3 times the RMS peak current, which is suitable for a DUT input inrush current test.
The 61809/61812/61815 models are 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, they 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 required by some regulatory standards.
With the intuitive 5″ LCD touch screen interface, users can quickly get familiar with the instrument’s operation. Remote interfaces include standard USB, LAN, and optional GPIB, CAN interface. Instruments can be controlled by computer and Chroma Softpanel software for fast digital operation. In addition, Chroma also provides control drivers where users can use LabVIEW software to program integration applications of the control system.

Grid Simulators High Power Density
An advanced digital control system and cooling technology allows for a form factor at 3U height as well as achieving outstanding hardware capabilities like 15kVA output power, 350VLN wide output voltage range, 1-phase / 3-phase output mode, 100% DC output, and regenerative function. Chroma has also improved transient capabilities, like rising / falling slew rate of output voltage, providing even a better power test solution for users.
For system applications, the 3U height form factor of Chroma 61809/61812/61815 occupies less space in the system cabinet, which can provide more space and flexibility for users. In addition, they also can be placed on a lab bench which is a source of convenience for the user.
Intuitive Touch Screen
Chroma 61809/61812/61815 models are equipped with a 5″ LCD touch screen interface providing users with an intuitive UI interface to quickly perform multiple settings and operations. The rotary knob can enlarge the display for the setting parameters of operation for fine-tuning of parameters. The display mode can expand the measurement value to full screen, making it easy to observe.
Universal AC Input Voltage Range
Chroma grid simulator models support wide AC input voltage range and is capable of supporting three phase input voltage ranging from 200VLL to 480VLL ± 10%. Applicable for most of the three phase 200VLL, 380VLL, 400VLL, 480VLL systems implemented around the world.
Power Line Disturbance (PLD) Functions
Chroma 61809/61812/61815 models include Power Line Disturbance (PLD) advanced programming functions and are capable of simulating various types of distorted voltage waveforms and transient conditions required by product validation testing. PLD functions include STEP, PULSE, LIST mode, and SYNTHESIS, Inter-harmonic, and Harmonic Measurement. The STEP and PULSE functions allow users to perform single or continuous step changes of output voltage. The LIST mode is a more versatile function as it allows users to compose complex waveforms of up to 100 sequences. With these programming modes, voltage waveforms required by immunity specifications such as IEC 61000-4-11/-4-13/-4-14/-4-28 can be easily achieved.
In addition, these advanced programming modes are easily set using the touch screen interface. For example, in LIST mode, the editing page can directly take the settings of all sequences and the search function can help quickly find the sequence if an adjustment is needed. Moreover, users can get more intuitive and convenient smartphone like programming as well as copying and pasting functions.
The SYNTHESIS function allows users to create periodic harmonic voltage waveforms up to 50 orders based on a 50/60Hz fundamental frequency. The Inter-harmonic 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 resonance points. The Harmonic Measurement function can measure 50th order harmonics of voltage or current and display values such as fundamental voltage, DC component, and total harmonic distortion.
Master-Slave Parallel Output Function
Chroma grid simulators provide master-slave parallel output functions, which can extend the output power when configuring up to 3 units in parallel. By connecting three 61815 regenerative grid simulators in a master-slave parallel setup, users can achieve a high power density configuration with a total output power of 45kVA at 9U height space.
