Introduction - Metek Sorensen XEL serie Manual De Operación

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.
