The Aim-TTi QL Series P SII range offers an unparalleled level of precision. They are high-performance, precision DC power supply units, designed for demanding laboratory and system applications. With advanced linear regulation and digital control, they offer 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 Series 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.
