The MORNSUN E0503D-1WR3 is a compact, fully isolated, dual-output DC-DC power module designed to provide stable positive and negative voltage rails. It features an ultra-wide input voltage range of 4.5–36V and delivers a regulated dual output of ±3.3V at a total continuous power of up to 1W (typically ±0.5W per output). The module incorporates reinforced isolation (1500VDC), ensuring high noise immunity and safety for sensitive analog and mixed-signal circuits. With high conversion efficiency, excellent line/load regulation, low output ripple & noise, and a wide operating temperature range (-40°C to +85°C), the E0503D-1WR3 is a robust solution for applications requiring symmetrical bipolar power. Its compact SIP package and compliance with international standards make it suitable for operational amplifiers, data acquisition systems, industrial sensors, and communication interfaces.
