Aim-TTi QL355P SII Power Supply Single 0-35V/0-5A

The Aim-TTi QL355P 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 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 50μs. Differential output noise is less than 350μV rms in CV mode and down to 20μA rms in CI mode. Of equal importance for critical applications in areas such as telecoms is common mode noise current (the noise current flowing between the output terminals and ground). This is less than 4μA rms on the QL Series - dramatically better than most other PSUs. 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.
