SX S
ERIES
PRODUCT OVERVIEW
Elgar’s SX Series AC linear power sources
are designed to drive non-linear, capacitive
input filter rectifier loads. They meet all the
electrical power requirements for testing
modern switch mode DC power supplies.
Increased peak power capacity and a
reduced physical size make the SX units
ideal for benchtop testing as well as for
automated DC power supply test systems.
FEATURES AND
BENEFITS
CONTINUOUS DUTY AT
150% RATED CAPACITY
Due to their conservative design, the SX
Series provides continuous duty at 150%
rated capacity into a linear resistive load
(see chart on page 25).
HIGH CREST FACTOR
The SX Series is ideal for power supply
test, with a crest factor capability of 3.5
and up to 6.1 on firing angles of less than
10 degrees from the voltage peak.
LOW EFFECTIVE OUTPUT IMPEDANCE
High impedance inhibits the quick transfer
of current to the load source, which
reduces peak current. Elgar linear sources
typically offer less than 0.05
Ω
, allowing
quick transfer of peak current to the load.
RANGE CHANGE RELAYS
The SX Series comes standard with
programmable range change relays,
making switching between the 0-130 and
0-260V ranges easy. This allows quick
testing of both U.S. and European
electronic equipment.
CONFIGURABLE
SX Series components are used as building
blocks for creating a full range of single,
dual and three phase AC power sources.
OUTPUT POWER VOLT AMPERE
RATING
Single-phase
500 VA to 5250 VA
Dual-phase 1000 VA to 10.5 kVA
Three-phase 1500 VA to 15.75 kVA
TWO YEAR WARRANTY
Elgar offers a two year warranty on the SX
Series power supplies.
OPTIONS
PROGRAMMABLE VIA IEEE-488 GPIB
The SX Series, when used with an Elgar
Plug-In Programmer, provides full GPIB
control of voltage, frequency, phase angle,
voltage dropouts and test readback of
output parameters.
TEST OPTION/BUILT-IN TEST
EQUIPMENT (BITE)
This optional feature is available when
used with an Elgar PIP 9012A, PIP 9023
or PIP 704 that also has the test option.
Depending on the PIP, the RMS voltage,
RMS current, frequency, phase angle and
RMS power in watts can be read from the
front panel or over the GPIB.
PROGRAMMABLE CURRENT LIMIT
When equipped with the test option (Built-
In Test Equipment/BITE), a current limit may
be programmed via the GPIB or from the
front panel, which if exceeded, will cause
system shutdown and status reporting.
REMOTE SENSE
This feature provides full programming
accuracy without sacrificing response time
and is available with Elgar Plug-In
Programmers and other selected oscillators
for 0.015% regulation.
DISCONNECT RELAY
The optional internal output relay connects
the load to the output of the power source
under GPIB control or from the front panel
keypad with a Plug-In Programmer.
EMC/SAFETY (SXE Models Only)
The 1751SXE has been designed to
meet the requirements for CE mark.
MATE QUALIFIED – EMBEDDED TMA
The SX Series can be modified to meet U.S.
Air Force (MATE) guidelines. All
requirements of MATE-STD-280673
including built-in TMA for CIIL interfacing
can be met when the SX is used with a
MATE-compatible Plug-In Programmer.
APPLICATIONS
The SX Series can maximize power supply
test productivity and improve test quality.
Key tests can be performed under program
control for repeatability and accuracy, such
as static line regulation and frequency
margins, dynamic line regulation to check
sudden line drops or missing cycles, start-
up time under various line conditions,
hold-up time and power sequencing,
inrush current testing, plus ramp-up and
ramp-down tests for soft start and power
failure signals.
High speed, high accuracy testing of DC
power supplies is now possible at a
reduced cost in a reduced package size.
The SX Series is designed for testing both
AC and DC switch mode power supplies.
