QS4A_1505S1.5UP – GAPTEC

The QS4A_1505S1.5UP is a galvanically isolated DC-DC converter module designed for applications requiring a regulated 5V output at 50mA from a nominal 15V input. It accepts an input voltage range of 13.5V to 16.5V (±10% tolerance around a 15V nominal). The module delivers 0.25W of output power with a typical efficiency of 75%. Isolation is implemented to provide electrical separation between the input and output stages, enhancing system safety and reducing ground loop issues. The device is specified for operation across a wide temperature range of -40°C to +105°C, enabling its use in harsh industrial environments. The compact module features internal filtering to minimize EMI and RFI, and incorporates short-circuit and overload protection to ensure robust performance and prevent damage under fault conditions. It is ideally suited for powering sensitive analog circuitry, instrumentation, and isolated communication interfaces.
