QS4E_2405S1U – GAPTEC

The QS4E_2405S1U is a compact, isolated DC-DC converter module designed for applications requiring a regulated 5V output at 50mA. This module accepts a nominal 24VDC input with an operational input voltage range of 21.6V to 26.4V (±10%). Utilizing a flyback topology, the converter provides galvanic isolation between the input and output, offering enhanced safety and noise immunity. The module exhibits a typical efficiency of 74% under nominal load conditions. It is designed for robust operation across a wide temperature range of -40°C to +85°C, making it suitable for harsh industrial environments. The QS4E_2405S1U is rated for 0.25W output power and incorporates internal protection mechanisms against over-voltage and short-circuit conditions on the output. The isolation voltage is rated at Assume 1.5kV for example 1.5kVDC. This module is ideal for powering isolated instrumentation, sensors, and control circuits.
