AMETEK Sorensen XPF Series

AMETEK Sorensen XPF Series

Product Overview:

  • Single & Dual output PowerFlex dc power supply - 420 Watts per output
  • High performance autoranging outputs, 60V and 20A maximum
  • True analog controls with digital functionality including S-Lock
  • Isolated tracking for easy series/parallel use - up to 120V o r 40A
  • GPIB, RS-232, USB and LAN interfaces; LXI class C compliance
  • Simultaneous display of output voltage and current for each output
  • Over voltage protection per output
  • Switchable remote or local sense




The Sorensen XPF is a new type of bench power supply designed to meet the need for flexibility in the choice of voltage and current. Typically, the maximum voltage and maximum current are not required simultaneously. The PowerFlexTM design enables higher currents to be generated at lower voltages within an overall power limit envelope. This is achieved by using the latest switch-mode technology.

The XPF60-20D are dual output DC power supplies with two completely independent and isolated outputs. If required, the outputs can be wired in series or parallel to achieve up to double the maximum voltage or double the maximum current. The new XPF60-20S is a single output version of the XPF60-20D providing 60V and 20A within its 420W power envelope.

The XPF Series has advanced digital features while keeping its simple to operate analog controls. The series
also has a remote programming option making the popular XPF perfect for some ATE applications. 
The interfaces included: LXI Class C Ethernet, GPIB, USB and RS-232/423. Please see the XPF download section forXPF60-20DP brochure that fully describes the advanced features.

XPF35-10 Power Envelope (each output)
XPF 35-10
The maximum current at any voltage setting is limited by the power envelope which is set to give 5 A at 35 A rising to 10 A at 12 V under all AC supply conditions (both outputs loaded). 
At lower output voltages the power is restricted by the 10 amps current maximum.
XPF60-20 Power Envelope (each output)
The maximum current at any voltage setting is limited by the power envelope which is set to give 7 A at 60 A rising to 20 A at 20V (both outputs loaded). 
At lower output voltages the power is restricted by the 20 amp maximum current.
