PVA Series Programmable Solar Cell Analog Power Supply
PVA Series Programmable Solar Cell Analog Power Supply
▲PVA Series Programmable Solar Cell Analog Power Supply
PVA series solar cell analog power supply adopts DSP digital control technology. Power inverter adopts new soft switch and low loss rectification technology. The power efficiency is over 95% in the wide voltage power output power range, with low ripple, high power density, dynamic With good characteristics and advanced process, it can simulate the condition of various solar panels (such as thin film batteries) under different weather conditions based on solar panel information.
▲Product performance characteristics：
|
• Adapt to a variety of photovoltaic panel types: single crystal, polycrystalline, amorphous, etc.
• Output mode MTTP mode and constant voltage, constant current, constant power output mode.
• Basic functions for universal test DC power supply programming.
• Automatic programming to control I-V curve output
(You can automatically program any number of curves and run by time)
• Simulate different types of solar array I-V curves
• Simulate I-V curves at different temperatures and light intensities
• Simulated PV array local shadow occlusion I-V curve
• Simulated scaling of I-V curves under full-day sunshine
• Static and dynamic MPPT performance test
• Simulate all-day cumulative energy metering
• High output current and voltage accuracy
• The conversion efficiency is as high as 95% or more, and the total harmonic THD is less than 5%, which has less harmonic pollution to the power grid.
• High degree of intelligence: friendly man-machine interface, LCD large screen display, curve, programming at a glance, touch operation, automatic data storage. The output can be configured with USB / RS232 / RS485 control interface, which can be operated by the local machine or by the host computer software.
