Chroma 62150H-600S Programmable Solar Array Simulator Power Supply
The Chroma 62150H-600S Programmable Solar Array Simulator Power Supply is a cutting-edge solution designed for the simulation of photovoltaic (PV) systems. It offers an impressive open circuit voltage (Voc) of up to 1000V and a short circuit current (Isc) of up to 25A, all packaged in a compact 3U height module that boasts industry-leading power density.
This simulator features a highly stable performance environment and a rapid transient response design, which is crucial for effective Maximum Power Point Tracking (MPPT) performance evaluation on PV inverter devices.
Equipped with high-speed and precision digitizing measurement circuits, the Chroma 62150H-600S provides a 100kHz A/D and 25kHz D/A control for accurate I-V curve simulation, significantly reducing the mains ripple effect from PV inverters. The built-in SAS I-V model allows convenient programming of Voc, Isc, Vmp, and Imp parameters, making I-V curve simulation seamless without the need for a PC controller.
Weather conditions such as irradiation, temperature changes, and shading can greatly influence the I-V curve output of real solar arrays. The Chroma 62150H-600S addresses this challenge by storing up to 100 I-V curves in its memory, with user-defined programming ranges spanning from 1 to 15,000 seconds. This feature allows for realistic simulations of I-V curves throughout the day, facilitating comprehensive testing of PV inverters and dynamic I-V curve transient analysis.
Designed for precision, this power supply incorporates a built-in 16-bit digital control system with exceptional voltage accuracy of 0.05% + 0.05% FS and current accuracy of 0.1% + 0.1% FS. This makes it ideal for real-time MPPT analysis and tracking, enhanced by a dedicated soft panel that enables data recording during static MPPT performance tests.
For applications requiring high power solar array simulation, the Chroma 62150H-600S is capable of parallel operation with multiple units. Its current range extends to 25A and voltage range to 1000V, providing a maximum power density of 15KW within the compact 3U package. Up to ten units can be connected in a Master/Slave configuration, achieving a total power output of 150kW for testing commercial PV inverters ranging from 10kW to 100kW. The innovative Master/Slave control mode facilitates swift and simple parallel operation, making it as effortless as using a standalone device.
Operation of the Chroma 62150H-600S is user-friendly, with control available via a front panel keypad or a remote controller through USB, RS232, RS485 (standard), with optional GPIB and Ethernet interfaces. Its compact 3U form factor makes it perfect for both benchtop setups and standard racking solutions.
