The F0512D-1WR3 is a high-performance 1W isolated DC-DC converter module from MORNSUN's E_D-1WR3 & F_D-1WR3 series, specifically designed for on-board power systems requiring a voltage isolated from the input power supply. This model features an input voltage range of 4.5V to 5.5V and provides a regulated 12V output with up to 84mA output current. Key features include continuous short-circuit protection, ultra-low no-load input current of 8mA, 3000VDC isolation voltage, and high efficiency up to 84% . The module operates reliably over a wide temperature range of -40°C to +105°C and features an international standard pinout for easy integration . It is ideal for applications in pure digital circuits, low-frequency analog circuits, relay drive circuits, and data exchange systems.
