200W Isolated DC-DCs with 250- to 1000-Vdc Input Range

Mornsun has added the 200W PV200-27Bxx to PV series to further meet customer demand for higher powers, based on the company’s 5- to 40-W ultra-wide & ultra-high input voltage dc-dc converters, which are widely used in new energy-related photovoltaic, energy storage BMS, high-voltage inverter and other industries.

The new series PV200-27Bxx has the following advantages:

1) Ultra-wide & ultra-high input voltage, high power, high efficiency – PV200-27Bxx series provide a wide input voltage range of 250- to 1000Vdc, power up to 200W to meet higher demands for high-power power supply in ultra-wide and ultra-high input voltage application, and high efficiency up to 87%, low power consumption and more energy-saving.

2) Complete protection, high reliability – PV200-27Bxx series have input voltage protection to avoid frequent restart of system to maintain the system’s stability. Offering MTBF over 300,000h, they have reverse input voltage protection, output short circuit, over-current and over-voltage protection.

These protections greatly reduce the probability of failure of the power supply itself while greatly enhance the safety performance of the module power supply and the load under abnormal working conditions.

3) CE certified (pending) – PV200-27Bxx series meet EN62109 standards (pending) with a certified voltage of 1000Vdc. The series offers isolation voltage up to 4000Vac and high reliability, to effectively protect the safety of the system.
