Datasheet

Bench and System use
The QL-P models include all of the manual control features of the standard models plus comprehensive
digital interfaces and rear terminals.
All power supply settings can be controlled via the bus. Voltage and current can be set to a resolution
of 1mV or 0.1mA for each main output, and to 10mV for the auxiliary output.
Actual voltage and current can be read back along with the power supply status.
Rear output terminals
Power and sense terminals are duplicated on the rear panel for rack mount applications or other
situations where rear connection is more appropriate.
Digital remote control
To meet the varying needs of today’s engineers, a comprehensive array of interfaces is provided.
RS-232, USB, GPIB and LAN (Ethernet) with LXI support are provided as standard. Each of the digital
bus interfaces provides full control of voltage, current, and output on/off, plus read-back of voltage,
current and status. The interfaces are at ground potential and are opto-isolated from the output
terminals.
GPIB
The GPIB interface is compliant with IEEE-488.1 and IEEE-488.2. Currently GPIB remains the most
widely used interface for system applications.
RS-232
An RS-232/RS-423 interface is provided for use with legacy systems. This type of serial interface
remains in common useage and is perfectly satisfactory for the control of power supplies because
data speed is not an issue.
USB
USB provides a simple and convenient means of connection to a PC and is particularly appropriate for small system use. A USB driver is provided which supports
Windows 2000, XP , Vista and Windows 7. Further versions will be supported as they are released.
LAN (Ethernet)
The LAN interface uses a standard 10/100 base-T Ethernet hardware connection with ICMP and TCP/IP Protocol for connection to a Local Area Network or direct
connection to a single PC. This interface supports LXI and is highly appropriate for system use because of its scalable nature and low cost interconnection.
LXI Compliance
The LAN interface is compliant with LXI-C. LXI (LAN eXtensions for Instrumentation) is the next-generation, LAN-based modular architecture standard for
automated test systems managed by the LXI Consortium, and is expected to become the successor to GPIB in many systems. For more information on LXI and
how it replaces GPIB, or operates along side it, go to: www.aimtti.com/go/lxi
IVI Driver
An IVI driver for Windows is included. This provides support for common high-level applications such as LabView*, LabWindows*, and HP/Agilent VEE*.
Compact design for bench or rack
The QL series are highly compact with a small footprint for bench use. Fold-away feet are incorporated which can be used to angle the front panel upwards.
Single output models are one-third rack width, whilst triple output models are two thirds rack width.
A universal rack mount tray is available which will mount one, two or three singles, one triple, or one triple plus one single.
On P versions, rear output terminals are provided for system use.
