QS4E_1518S1U – GAPTEC

The QS4E_1518S1U is a galvanically isolated DC-DC converter module designed for applications requiring a regulated 18V output from a nominal 15V DC source. This module accepts an input voltage range of 13.5V to 16.5V (±10% tolerance around the nominal 15V). It delivers a regulated 18V output at a current of 13.8mA, providing a power output of 0.25W. The device incorporates robust isolation, offering significant protection between the input and output stages. The module boasts a typical efficiency of 74% under nominal operating conditions. Its operating temperature range spans from -40°C to +85°C, making it suitable for demanding industrial environments. The isolated topology minimizes ground loop issues and enhances system noise immunity. Internal circuitry provides short-circuit and over-temperature protection, ensuring reliable operation and preventing damage to the module and connected loads. The compact design facilitates easy integration into various PCB layouts.
