Choose voltage and current combinations to suit your applications
The XPF series from Sorensen is a different type of laboratory power supply designed to meet the need for flexibility in the choice of voltage and current.
A conventional power supply has a fixed current limit giving a power capability that reduces directly with the output voltage.
The PowerFlex design of the XPF series enables higher currents to be generated at lower voltages within an overall power limit envelope.
Each output can provide considerably higher current than a conventional power supply of the same maximum voltage and power (see power curve).
Example voltage & current combinations include 60V/7A, 42V/10A, 28V/15A, and 20V/20A.

Building upon success
The XPF60-20D is the latest models in the XPF series from Sorensen and were developed from the XPF60-20, one of the most successful power supplies ever.
Independent and simultaneous output control
The Both On/Both Off button is in addition to the individual switches for each output, and allow both outputs to be turned on or off synchronously by a single button press.
Synchronous switching of the outputs is of increasing importance for circuitry which can be damaged if one voltage rail is present without the other.
Low noise and good dynamic response
The PowerFlex regulation system used on the XPF60-20DP combines a high frequency pre regulator with a linear post regulator to give both low noise and good transient response. Each output can operate in constant voltage or constant current mode with automatic crossover and mode indication.
