250- to 3300-Vdc Input 32W Isolated Dual-Output DC-DC Converter

Mornsun has launched the PV75-36D 32-Watt dual-output dc-dc converter. The PV75-36D supports a maximum output of 75W for 2 seconds during start-up, and provides a continuous steady-state output of 32W. Output 1 is 15V/2A steady-state output and Output 2 provides up to 43W, and at room temperature, Output 2 can charge a 560uF capacitor to 400V in 2 seconds.

The PV75-36D is expected to be widely used in applications of high voltage flexible DC power transmission and ultra-high voltage SVG power supply.

This new PV75-36D series adopts “Patented multistage series technology,” which not only solves the difficulties in design of the industry for startup, module startup timing, module input voltage equalization, system protection, high isolation withstand voltage, wide operating temperature, etc., but also simplifies the customer's system solution and improve the reliability while reducing the cost.

PV75-36D

The PV75-36D series features a 250- to 3300-Vdc ultra-wide input voltage range and its isolation voltage is up to 6000Vac.The dimension is 220 x 157 x 40mm which makes it 65% smaller than other conventional products in the market. Besides, -40⁰C to +85⁰C (power is derated above 60⁰C) industrial operating temperature range and meeting 5000m altitude application requirements (power is derated above 2000m) make PV75-36D series suited for environments of thin air and outdoor high altitude with large temperature difference between day and night.
