Current Range

0~40, 1500A (System)

Solar Array Simulator DC Power Supplies by Chroma provide programmable simulation of Voc (open circuit voltage) up to 1800V and Isc (short circuit current) up to 30A. The 62000S-H series 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 advantages to MPPT performance evaluation on PV inverter devices.

High Speed & Precision Digitizing Measurement

The 62000H-S series 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 62000H-S Series has a built-in 16 bit digital control and precision voltage & current measurement circuits with a voltage accuracy of 0.05% + 0.05% F.S. 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 softpanel. The user can also enable the data recording function on the softpanel during the static MPPT performance test.

IV Curve Simulation

A real solar array is influenced by various weather conditions like irradiation, temperature, rain, and shade by trees or clouds, which will affect the I-V curve output. The 62000H-S 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.
