10W DC-DC with 200- to 1,200-Vdc Input Range Operates to 70°C

PV10-27C050524 from Mornsun is a regulated dc-dc converter with an ultra-wide and ultra-wide input range of 200- to 1200-Vdc, which design to meet standards of CSA-C22.2 No.107.1, EN62109. The products feature high efficiency, high reliability, high insulation and a high level of safety protection.

The application circuit illustrated above is recommended for use in extremely-harsh EMC environments.

This type of power supply is widely used in renewable energy industries such as photovoltaic, power generation, energy storage, inverters and high-voltage dc conversions. The converters provide multiple protection features and guarantee stable and safe operating environments even under abnormal working conditions.

These dc-dc converters deliver full output power to 50°C and derate linearly to 40% power at 70°C (for input voltages between 200Vdc and 300Vdc these converters are also derated for temperatures below -25°C to 55% power at -40°C).

Summary of features:

  • Ultra-wide 200- to 1200-Vdc input voltage range
  • Industrial grade operating temperature -40°C to +70°C
  • High I/O isolation test voltage of 4000Vac (Input-output), three-way isolation output of 3500Vac
  • Meets reinforced insulation
  • High efficiency, Low ripple & noise
  • High reliability, Long service life
  • Input reverse polarity and undervoltage protection, output short circuit, overcurrent and overvoltage protection
  • Meets 5000m altitude requirements
  • RoHS
