Aim-TTi QL355  – Precision Linear Laboratory Power Supply

The Aim-TTi QL355  is part of the advanced QL Series II of linear regulated DC power supplies, designed for applications requiring exceptional precision, low noise and stable output performance. The instrument provides adjustable output ranges of 0–35 V / 3 A or 0–15 V / 5 A, enabling higher current at lower voltages for greater flexibility.

Using high-quality linear regulation technology, the QL355 SII delivers very low ripple and noise (typically <0.35 mV rms) and excellent load and line regulation, making it ideal for powering sensitive electronic circuits and precision measurement setups.

The instrument features precise digital control with 1 mV voltage resolution and highly accurate voltage and current settings. Multiple non-volatile memory locations allow users to store frequently used configurations for faster setup.

With its robust laboratory-grade design, excellent dynamic performance and advanced protection features such as OVP (over-voltage protection) and OCP (over-current protection), the QL355 SII provides reliable power for demanding development and testing environments.

The compact bench-top design also supports rack-mount integration, making the instrument suitable for both standalone laboratory use and system applications.
