The QPS1 internal power supply provides DC power for systems up to 66 spaces. The QPS1 is plug-and-go with an AC connection for a Q137 all-in-one power module, or the Q101/Q102 power module pair. A DC connection for a QDH power harnesscarries power to the modules.
To calculate the power needed by your system, add the current for each voltage needed by each module. Since most modules draw less than 30ma on the +/-15 volt rails, and some draw none, the QPS1 will typically power a system of 66 spaces or more. You can also use our Spreadsheet or SynthInventto calculate these values.
