Chroma 62020H-150S solar analog power supply

Chroma 62020H-150S solar analog power supply,It can simulate the open circuit voltage (Voc) of solar cell arrays up to 600V and short-circuit current (Isc) up to 25A in 3U high power modules, and can simulate the output I-V curve of solar cells. It can be applied to the maximum power tracking (MPPT) performance testing of photovoltaic inverters, micro inverters, and solar chargers.

Chroma 62020H-150SPhotovoltaic simulation power supplyThere are 100 user programmable input states on the front panel for automatic testing applications and lifecycle ON/OFF testing. In addition,Chroma 62020H-150SEquipped with 16 bit high-resolution digital control and excellent visibility vacuum fluorescent display readout function.

Chroma 62020H-150SPhotovoltaic simulation power supplyThe operation is very simple, using standard USB/RS232/RS485/APG control interfaces and optional GPIB&Ethernet control interfaces from the front panel buttons or remote controller. It has a delicate size of 3U and can be easily stacked on the machine with a standard rack.

Chroma 62020H-150SAnother unique feature is the ability to establish complex DC transient waveforms. This function can perform voltage leakage, transient interruption, and other voltage changes tests on devices, making it an ideal choice for testing aviation equipment, solar inverters, and other devices that may cause voltage interruptions. Its application scope includes DC/DC converters and inverters, voltage drop testing, engine start-up simulation, automatic battery charging, electronic product lifecycle testing, and more.

Chroma 62020H-150S solar analog power supply

Chroma 62020H-150S solar analog power supplyFeaturing low output noise and ripple, excellent regulation of mains disturbances, load regulation, and fast transient response.

The master/slave parallel and series operation modes can reach up to 150KW

When high power is required, two or more power supplies are generally connected in parallel or series. The Chroma 62000H series power supply has a master/slave control mode, making the series/parallel operation mode fast and easy. In this mode, the master machine sets values and downloads data to the slave machine, so programming is simple and automatic current sharing is used.

Application of solar cell array simulation power supply*

Chroma 62020H-150SIt has an I-V curve that can simulate solar panels, and users can edit I-V curves under various temperatures and lighting conditions, as well as curves under special shielding. This can be applied to the maximum power tracking (MPPT) efficiency testing of solar inverters. As shown in Figure A&B, users can easily edit the I-V curve using SoftPanel software and download it to the internal memory of the single machine. It can also output and measure the maximum power tracking status and records of the solar inverter in real time.
