QT8E_1209S1U – GAPTEC

The QT8E_1209S1U is a galvanically isolated DC-DC converter module designed for point-of-load applications requiring a stable 9V output at 28mA. This module accepts a nominal 12VDC input, tolerating a ±10% variation (10.8V to 13.2V). Isolation is provided to enhance system safety and reduce ground loop noise. With a typical efficiency of 73%, the converter delivers 0.25W output power while minimizing heat dissipation. The robust design allows for operation across a wide temperature range of -40°C to +85°C, making it suitable for harsh industrial environments. The module employs internal regulation and filtering to maintain a consistent output voltage, even with input voltage fluctuations or load variations. It is designed for through-hole mounting and utilizes a compact form factor for space-constrained applications. The isolation voltage is not specified; further datasheet review is required to confirm this parameter.
