* Quad-mode switching
The main outputs on most TTi power supplies are isolated and have automatic crossover between CV and CI modes. This allows wiring in series or parallel in order to achieve higher voltages or higher currents. The PL series also features �quad-mode� switching on duals and triples which allows push-button selection of four modes of operation - isolated, series, series-tracking, or parallel.

# Multi-Range and PowerFlex
The QL Series has multiple output ranges which allow higher currents at lower voltages. The voltage and current levels shown in the table are not available simultaneously.
The PowerFlex system enables a power supply to provide higher currents at lower voltages. For example, each output of the CPX400A can provide 7 amps at 60 volts. As the voltage is reduced, the maximum current available increases up to a maximum of 20 amps at 20 volts or below.

** Multi-mode switching
The EX752M incorporates switching that enables it to operate as a dual power supply with two independent and isolated outputs, or as a single power supply of double the power. As a dual, each output provides 0 to 75V at 0 to 2A (mode A). As a single the output can be selected as either 0 to 75V at 0 to 4A (mode B) or 0 to 150V at 0 to 2A (mode C). In single modes, the unused half of the unit becomes completely inoperative and its displays are blanked.
