3S7BE_1209D3U – GAPTEC

The 3S7BE_1209D3U is a compact, galvanically isolated DC-DC converter module designed for applications requiring dual output voltage rails. It provides two regulated 9V outputs, each capable of delivering 167mA, from a nominal 12V input. The input voltage window is tightly controlled, accepting a range of 11.4V to 12.6V (±10% tolerance). This module achieves a high efficiency of 90% under typical operating conditions, minimizing power dissipation and heat generation. The robust design allows for operation across a wide temperature range of -40°C to +85°C, suitable for harsh industrial environments. Isolation is implemented to provide electrical separation between the input and output, enhancing system safety and reducing noise. The 3W power rating ensures adequate power delivery for various low-power electronic circuits and systems.
