PV DC-DC Converter

MORNSUN 15W and 40W power supply modules, PV15/PV40-29Bxx series, provide 200-1500VDC input voltage, high isolation voltage of 4000VAC and can significantly be used at high altitudes up to 5000m.

The photovoltaic industry is moving from nominal 1000VDC to 1500VDC. Higher-voltage systems enable longer strings, which allow for fewer combiner boxes, less wiring and trenching, and therefore less labor.

Input voltage from 200VDC to 1500VDC allows longer strings used in the PV system.

Suitable for high-altitude applications ( up to 5000 meters )

Most of the PV systems are installed in harsh environments or at high altitude fields. PV15/PV40-29Bxx are designed to meet the application requirement to ensure the systems reliability and safety.

Input under-voltage protection ensuring system stability

A PV system converts the sun's radiation into usable electricity and also powers itself. As the unstable sunlight intensity, voltage to the control system is also various and may lead to system restarts frequently. PV15/PV40-2 9Bxx series are designed with input under-voltage protection which can protect system stability from frequent restart.

PV15/PV40-29Bxx series are suitable for various applications such as photovoltaic combiner, photovoltaic inverter, high voltage switching, etc.
