QL Series II DC Supplies: High Resolution

Unmatched precision

The QL series 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.

Why do I need a precision PSU?

Every engineer needs to have confidence in their equipment. A power supply is one of the most fundamental of bench instruments.

You need certainty that the voltage you apply to a circuit is precisely what you want it to be. You need certainty that the output of your power supply is clean and stable.

You need the ability to define a precise voltage at the load and maintain regulation independent of lead resistances.
