Beijing High-tech Dynamic Power
HTP III 300-48-3000 Solar Convertor

Introduction

HTP III 300-48-3000 is an isolated DC/DC converter with MPPT (Maximum Power Point Tracking) function. It can extract maximum power from the solar panels in real time throughout the day. The module can work with outstanding reliability, efficiency and power density. It is specially designed for telecom, network access and data center applications.

Features

  • High efficiency and high power density: 96.3% efficiency and 41.72W/in³ power density. MPPT efficiency is > 99%.
  • Digital control: Digital primary and secondary control for monitoring and regulation.
  • High reliability design: Front-to-back airflow with one fan.
  • Disconnect mains when hazardous input: Self-protection against unsustainable input voltage.
  • Excellent EMC performance: Low interference and high susceptibility for better compatibility.
  • Global approvals: Meets CE, UL, and TUV standards.
