QS4E_1509S1U – GAPTEC

The QS4E_1509S1U is a galvanically isolated DC-DC converter module designed for applications requiring stable 9V output at 27.7mA 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 provides a single, regulated output and offers 500VDC isolation between input and output stages. Key specifications include a typical efficiency of 74%, ensuring minimal power dissipation and thermal management concerns within the operating temperature range of -40°C to +85°C. The compact design and robust isolation characteristics make it suitable for sensitive analog circuitry, instrumentation, and industrial control systems where ground loop elimination and precise voltage regulation are critical. The power output is rated at 0.25W.
