200- to 1100-Vdc Ultra-Wide Input Voltage DC-DCs Deliver up to 120W

Mornsun recently launched the enclosed 120W PV120-27Bxx series which offers four output voltages-12Vdc, 15Vdc, 24Vdc, and 48Vdc. The PV series now provides six output power ratings including 5W, 10W, 15W, 40W, 120W, and 200W.

The PV120-27Bxx series provides a wide input voltage range of 200- to 1100Vdc, and high efficiency up to 89%, low power consumption and is more energy-saving. These dc-dc converters are designed for applications such as photovoltaic power generation, energy storage BMS and high voltage inverter etc.

These dc-dc converters have a MTBF over 300,000h and 4000Vac isolation voltage and excellent temperature characteristics. The lowest output power derating is 85% in the range of -40℃ to -25℃ and 60% in the range of 55℃ to 70℃

This series have reverse input voltage protection, input under-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.

This series meets the requirement of 5000m altitude application without derating at 2000m altitude which is suitable for high altitude outdoor occasions with rarefied air and big temperature difference between day and night.

Summary of features:

  • Ultra-wide input voltage range of 200- to 1100Vdc
  • 4000Vac high isolation voltage
  • Industrial grade operating temperature: -40℃ to +70℃
  • Efficiency up to 89%
  • Input under-voltage protection, reverse input voltage protection, output short circuit, over-current, over-voltage protection
  • High reliability, long lifespan
  • Meet 5000m altitude requirements
