SL AND B SERIES

PRODUCT OVERVIEW

Elgar SL and B Series power sources are
wide range, solid-state linear amplifiers
that convert the incoming line to low
distortion, stable sine wave power.

These solid-state frequency changers are
benchtop/19" rackmount units that can be
driven over their full voltage and frequency
ranges by fixed, variable or programmable
plug-in oscillators.

The SL and B’s offer overload and over­temperature protection, can operate
continuously at up to 150% rated capacity,
and provide up to three output voltage ranges.

FEATURES AND
BE N E FITS

CONTINUOUS DUTY AT
150% RATED CAPACITY

Due to their conservative design, the
SL Series provides continuous duty at 150%
rated capacity into a linear resistive load,
while the B Series models are rated at 100%.

LOW HARMONIC DISTORTION

The SL and B Series power sources
provide low harmonic distortion normally
below 0.3% midband, 0.6% over the full
frequency range.

WIDE FREQUENCY RANGE

Elgar AC power sources offer frequencies
from 45 Hz to 5 kHz at full rated power.
(optionally expandable to 10 kHz)

CONFIGURABLE

SL and B Series components can b e 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 120 VA to 18 kVA
Dual phase 240 VA to 18 kVA
Three phase 150 VA to 36 kVA

WARRANTY

Elgar offers a two year warranty on the SL
and B Series power supplies.

EMC/ SA FET Y (S LE Models Only)

The 1001 SLE and 1751 SLE have
been designed to meet the

requirements for the CE mark.

OPTIONS

PROG RAMMABLE VIA IE E E -448 G P IB

Elgar’s SL and B Series, when used w ith a
Plug-In Programmer, provide full G PIB
control of voltage, frequency, phase angle,
voltage dropouts and test readback of
output parameters.

RANGE CHANGE RELAYS

An optional internal range change relay
switches between 130 VAC and 260 VAC
ranges under GPIB control or front panel
local control when used with a P I P or a
modified oscillator.

TEST OPTION/BUILT-IN
TEST E Q U IPME NT (BIT E)

This feature is available when used with
an Elgar PIP9 012A, PIP9 023 or P I P704 that
also has the test option. Depending on the
PIP, the R MS voltage, RM S current,
frequency, phase angle and true power in
watts can be read from the front panel or
over the GPIB.

PROGRAMMABLE CURRENT LIMIT

When equipped w ith the test option (Built­in Test Equipment/B IT E), 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.

APPLICATIONS

The linear design of the SL and B Series
provides a highly regulated, clean sine
wave, making these units ideal for linear
loads in general purpose test applications
as well as for Automatic Test Equipment
systems and avionics testing.
