QL Series P SII Power Supply Single/Dual Output Range - Aim-TTi QL355P, The Aim-TTi QL355P SII offers an unparalleled level of precision. It is a high-performance, precision DC power supply designed for demanding laboratory and system applications. With advanced linear regulation and digital control, it offers exceptional accuracy, stability, and versatility. Voltage and current are controlled using instrumentation quality 16-bit DACs enabling voltages to be set to 1mV resolution even at full output voltage. Indeed, the accuracy is sufficient for the QL to be used as a calibration source for some hand-held DMMs. The QL series uses pure linear technology and offers unrivalled performance in terms of regulation, output noise and dynamics. Line and load regulation are close to the limit of measurement. Recovery time from transient current pulses is better than 50s. Differential output noise is less than 350V rms in CV mode and down to 20A rms in CI mode. Of equal importance fo
