Download Product DatasheetThe Chroma 62150H-600S Programmable Solar Array Simulator Power Supply provides simulation of Voc (open circuit voltage) up to 1000V and Isc (short circuit current) up to 25A. It also provides an industry-leading power density in a small 3U high package. The solar array simulator is highly stable and has a fast transient response design, which are both advantageous to MPPT performance evaluation on PV inverter devices.
The Chroma 62150H-600S Power Supply has many unique advantages including high speed & precision digitizing measurement circuits with a 100kHz A/D, 25kHz D/A controlled I-V curve and a digital filter mechanism. It can simulate an I-V curve accurately and clear the mains ripple effect from the PV inverter. In addition, the built-in SAS I-V model in the standalone unit can easily program the Voc, Isc, Vmp, and Imp parameters for I-V curve simulation, without a PC controller.
The real solar array is influenced by various weather conditions such as irradiation, temperature, rain and shade by trees or clouds, which will affect the I-V curve output. The Chroma 62150H-600S Power Supply is capable of storing up to 100 I-V curves into the simulator memory, with a programmed time interval range of 1-15,000 seconds. It can simulate the I-V curve from the early morning to nightfall for PV inverter testing or dynamic I-V curve transient testing.
The Chroma 62150H-600S Power Supply has a built-in 16 bit digital control and precision voltage & current measurement circuits with a voltage accuracy of 0.05%+0.05%FS and a current accuracy of 0.1%+0.1%F.S. It is ideal for real time MPPT analysis and tracking monitoring for PV inverters through our soft panel. The user can also enable the data recording function on the soft panel during the static MPPT performance test.
When high power solar array simulation is required it is common to connect two or more power modules in parallel. The Chroma 62150H-600S Power Supply with a current range up to 25A and a voltage range up to 1000V offers a high power density envelope maximum of 15KW in a 3U package. It can easily parallel up to ten units in a Master/Slave configuration to provide 150kW with current sharing and synchronized control signals for commercial PV inverter (10kW – 100kW) testing. The Chroma 62150H-600S Power Supply has a smart Master/Slave control mode that makes the parallel operation fast and simple. In this mode, the master scales values and downloads data to slave units so that the programming is as simple as using a standalone unit.
The Chroma 62150H-600S Power Supply is very easy to operate from the front panel keypad or from the remote controller via USB / RS232 / RS485 / APG (standard) and GPIB & Ethernet (optional). Its compact size (3U) makes it ideal for both benchtop and standard racking.
