Chroma 62150H-1000S Programmable Solar Array Simulator Power Supply
The Chroma 62150H-1000S Programmable Solar Array Simulator Power Supply is engineered to provide an advanced simulation of Voc (open circuit voltage) up to 1000V and Isc (short circuit current) up to 25A, all housed in a space-efficient 3U high package. This state-of-the-art power supply boasts an impressive power density, ensuring stability and quick transient response, crucial for evaluating MPPT performance in PV inverter devices.
With a slew of remarkable features, the Chroma 62150H-1000S integrates high-speed & precision digitizing measurement circuits, featuring a 100kHz A/D and 25kHz D/A controlled I-V curve simulation alongside advanced digital filter mechanisms. These capabilities ensure accurate I-V curve simulations free from mains ripple effects, streamlining the assessment of PV inverter performance.
This innovative power supply acknowledges real-world variables affecting solar output, such as irradiation, temperature, rain, and shading from trees or clouds. It can store up to 100 I-V curves in its memory with programmable intervals ranging from 1 to 15,000 seconds, effectively simulating sunlight conditions from dawn through to dusk for comprehensive PV inverter testing and dynamic I-V curve transient examinations.
The precision of the Chroma 62150H-1000S is reinforced by its 16-bit digital control and accurate voltage & current measurement circuits, boasting a voltage accuracy of 0.05% + 0.05% FS and a current accuracy of 0.1% + 0.1% FS. This makes it an ideal choice for real-time MPPT analysis and monitoring of PV inverters, with an optional data recording function available through an intuitive softpanel interface during static MPPT performance testing.
To meet high power simulation needs, the Chroma 62150H-1000S supports multiple power modules in parallel configurations, with a current range reaching up to 25A and a voltage range of 1000V, allowing for a maximum power density envelope of 15KW in a 3U unit. With the ability to connect up to ten units in a Master/Slave configuration, it can deliver a remarkable 150kW for testing commercial PV inverters (ranging from 10kW to 100kW). The smart Master/Slave control mode simplifies parallel operations, as the master unit scales values and downloads data to slave units seamlessly.
User-friendly operation is a hallmark of the Chroma 62150H-1000S, which can be controlled via the front panel keypad or remotely through standard USB, RS232, RS485, and APG connections, with optional GPIB and Ethernet interfaces available. Its compact 3U design makes it versatile for both benchtop use and standard racking installations.
