QL355T

Product information "QL355T "

The Aim-TTi QL355T SII is a high-precision triple-output DC power supply designed for demanding laboratory, research, and industrial applications. It features two fully adjustable outputs rated at up to 35 V and 5 A, along with an additional auxiliary output for powering logic circuits and low-power devices.

Built with advanced linear regulation technology, the QL355T SII delivers exceptionally low noise and high stability, making it ideal for sensitive analog and mixed-signal applications. The unit supports independent, series, and parallel tracking modes, allowing flexible configuration for higher voltage or higher current requirements.

A clear digital display provides accurate voltage and current readback, while intuitive controls ensure precise adjustment. Comprehensive protection features guarantee safe operation, and its robust construction ensures long-term reliability in professional environments.
