200- to 1500-Vdc Input DC-DCs for PV Power Systems
Mornsun recently released new 15W and 40W power supply modules, PV15/PV40-29Bxx series, which provide ultra-wide 200- to 1500-Vdc input voltage, high isolation voltage of 4000Vac and can be used at high altitudes up to 5000m. The ultra-wide input voltage range makes these dc-dc converters suitable in a wider variety of designs from under 1,000Vdc system to emerging 1,500Vdc systems. Higher-voltage systems enable longer strings, which allow for fewer combiner boxes, less wiring and trenching, and therefore less labor.
In addition, many 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. The PV15/PV40-29Bxx series are suitable for various applications such as photovoltaic combiner, photovoltaic inverter, high voltage switching, etc.
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.
Features include: 200- to 1500-Vdc ultra-wide input voltage; Operating temperature range of -40 to +70 degrees C; Isolation voltage of 4000Vac; High efficiency, low ripple & noise; Meet EN62109 standard; Suitable for high-altitude applications (up to 5000 meters); and Input under-voltage, reverse voltage, output short-circuit, over-current, over-voltage protection.
