Model 1751SL AC Power Source
with 400SD Plug-in Oscillator Module
Elgar Model 1751 SL AC Power Source is
a solid-state frequency changer and is ideal for general
applications, as well as ATE systems and avionics testing.
Includes the Elgar 400SD Plug-in oscillator module.
Also includes roll around cart and dust cover. This power
supply is used but in good working condtion. It is currently
setup to accept a 230VAC 1PH input and then output 0-230VAC
1PH at a variable frequency of 44-5100 Hz. Power rated
at 1750 VA.
SL Series power source is a wide range, solid-state linear
amplifier that converts the incoming line to low distortion,
stable sine wave power. These solid-state frequency changers
can be driven over their full voltage and frequency ranges
by fixed, variable or programmable plug-in oscillators.
The SL series offer overload and overtemperature protection,
can operate continuously at up to 150% rated capacity
and provide up to three output voltage ranges.
400SD PLUG-IN OSCILLATOR
Series 400SD variable frequency oscillators are plug-in
which provide variable frequency signals for the Elgar
AC Power Sources. The
frequency is determined by four decade switches on the
400SD oscillator plugs into the front panel of the Elgar
source and is secured by two captive screws. Frequency
output of the Model
400SD is controlled by four decade switches and a X1, X10,
X100 frequency range switch. The decimal for reference
silkscreened on the oscillator front
panel between the center two decade switches. Frequency
resolution is 1 part
frequency limit LED on the front panel of the oscillator
if a frequency below 44 Hz or a frequency above 5100 Hz
is selected. If this
occurs, the output of the oscillator will drop to zero.
When a proper frequency
is selected, the Limit light will go out and the oscillator
output will rise at an
exponential rate to full output in about 250 miIIiseconds.
linear design of the SL 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.
