• This model features LAN (LXI), USB and RS-232 for digital remote control
• Duplicate rear terminals

The Sorensen XPF series 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.

Several models available

Sorensen offers several models in its XPF power supply series. Listed below is an overview of main differences in each.

“P” models have RS-232, USB and LXI compliant LAN interfaces for digital remote control, plus duplicate rear terminals.

Power envelopes for these units can be viewed below.

Sorensen XPF “P” models offer full remote control and read-back using RS-232, USB or LAN (compliant with LXI class C). All interfaces are at ground potential and opto-isolated from the output terminals. Note: Remote/Local Sense, is manually selectable only.

RS-232

• Standard 9-pin D connector. Baud rate 9,600

USB

• USB 2.0 connection (backwards compatible with USB 1.x). Operates as a virtual COM port

Ethernet (LAN)

• Standard 10/100 base-T hardware connection. ICMP and TCP/IP Protocol for connection to Local Area Network or direct connection to a single PC.

The XPF series are fitted with newly designed output terminals. As well as acting as conventional binding posts for bare wires, spade connectors, or standard 4mm plugs, these can accept a 4mm safety plug with rigid insulating sleeve, a requirement specified by an increasing number of laboratories for safety reasons. Limited opening length combined with raised insulated shoulders also make these terminals “touch proof” for voltages up to 250V.

Each output incorporates remote sense terminals that can be enabled or disabled at the flick of a switch. Remote sensing is essential for maintaining precise regulation at the load and true metering of the load voltage.

Low noise and good dynamic response

The PowerFlex regulation system used on the XPF Series 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.
