The new T3PS series are single-output multi-range programmable switching DC Power Supplies covering a power range of up to 720 W. This series of products offers five models with rated voltages of 30 V, 80 V, 160 V, 250 V and 800 V, and 360 W and 720 W maximum output powers. The multi-range feature allows for a flexible and efficient configuration of voltage and current within the rated power range. A maximum of two units in series and a maximum of three units in parallel can be connected for applications requiring Voltage/Current higher than the rated output. The combination of the multi-range power output feature and series/parallel operation capability of the T3PS series significantly reduces the cost by accommodating the projects with a wide range of power requirements.

When the power supply is configured so that the total output (current x voltage output) is less than the rated power output, the power supply functions as a typical constant current, constant voltage power supply. If, however, the power supply is configured such that the total output (current x voltage output) exceeds the rated power output, the effective output is limited to the power limit or the operating area of the unit. In this case, the output current and voltage then depend purely on the load value. The graphs above display the operating areas of each power supply.

The T3PS has selectable slew rates for CC and CV modes. This gives the T3PS power supply the ability to limit the current/voltage draw of the power supply. Slew rate settings are divided into High-Speed Priority and Slew Rate Priority. High-Speed Priority mode disables slew rate settings for CC or CV mode. Slew Rate Priority mode allows for user-adjustable slew rates for CC or CV mode. The rising and falling slew rate can be set independently.

The T3PS DC power supplies employ a bleed resistor in parallel with the output terminals. Bleed resistors are designed to dissipate the power from the power supply filter capacitors when power is turned off and the load is disconnected. Without a bleed resistor, power may remain charged on the filter capacitors for some time and be potentially hazardous.

In addition, bleed resistors also allow for smoother voltage regulation of the power supply as the bleed resistor acts as a minimum voltage load. The bleed resistance can be turned on or off using the configuration settings.
