The Aim-TTi QL355TP SII represents the next generation of high performance laboratory power supplies, maintaining the tradition started with the PL series in 1980 and continued throughout more than two decades.

The Aim-TTi QL355TP SII offers an unparalleled level of precision. Voltage and current are controlled using instrumentation quality 16 bit DACs enabling voltages to be set to 1mV resolution even at full output. Indeed, the accuracy is sufficient for the QL to be used as a calibration source for some hand-held DMMs.

The user interface of the QL series has been painstakingly designed to provide rapid control whilst guarding against any possibility of error. Unlike other digitally controlled units, the QL series provides both numeric and rotary control. Illuminated keys and display legends provide instant confirmation of settings and status.
