AMETEK XEL Series 60V and below - Manual (Page 8)

Introduction
The XEL Series has the following key features:
• Linear regulation for ultra-low output noise and fast transient recovery
• High accuracy four digit fixed-resolution meters
• True analog controls for quick and intuitive adjustment of voltage and current
• DC output switch to check settings before applying them
• Remote voltage sensing for exceptional load regulation
• Current meter averaging to reduce jitter with rapidly varying load currents
• High power density - up to 94 watts from an ultra-compact 3U ¼-rack case size
• Significantly higher energy efficiency than conventional linear regulated designs by using
an advanced phase-controlled pre-regulator
• Low current range giving ten times greater meter resolution and finer low current setting
• V-Span allows the user to redefine the end-stop values of the voltage control, giving high-
resolution analog control over the exact voltage range needed
• S-Lock digitally locks voltage and current settings at the touch of a button
• Setting limits can be viewed at any time
• Safety binding post terminals are touch-proof and uniquely accept fixed shroud 4mm
plugs as well as standard plugs, bare wires and fork connectors
The XEL-P Series is the programmable (remote control) version of the XEL Series and duplicates
all of its manual control features. RS-232, USB and LXI compliant LAN interfaces are fitted as
standard; GPIB is a factory option.
• Full bus interfacing permitting remote control and readback via either RS232, USB, LAN
(LXI) or GPIB (IEEE-488). GPIB is a factory fitted option.
• Simple command structures which make programming particularly easy regardless of
which interface is used. The commands are consistent with other power supply families
such as the XDL-P making inter-changeability straightforward.
• All power supply settings can be controlled via the bus. Voltage and current can be set to
a resolution of 1mV and 0.01mA (10mV on 120V and 250V models). Actual voltage and
current can be read back together with the power supply status.
• An IVI driver is supplied which provides support for common applications such as
LabView*, LabWindows*, and Agilent VEE**.
• Single XEL-P models additionally offer remote analog control of output voltage and current
which can be used independently or in parallel master-slave configurations. On 120V and
250V models the remote control inputs are galvanically isolated from the output.
