SAFETY NOTICE
Before applying power to the system, verify that the SW Series unit is configured properly for the user’s
particular application.
WARNING!
Hazardous voltages in excess of 280 VRMS, 600V peak may be present when
covers are removed. Qualified personnel must use extreme caution when
servicing this equipment. Circuit boards, test points, and output voltages
may be floating above (below) chassis ground.
Installation and service must be performed by qualified personnel who are aware of dealing with attendant
hazards. This includes such simple tasks as fuse verification.
Ensure that the AC power line ground is connected properly to the SW Series unit input connector
or chassis. Similarly, other power ground lines including those to application and maintenance
equipment must be grounded properly for both personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting the
input/output power cables.
During normal operation, the operator does not have access to hazardous voltages within the
chassis. However, depending on the user’s application configuration, HIGH VOLTAGES
HAZARDOUS TO HUMAN SAFETY may be generated normally on the output terminals.
Ensure that the output power lines are labeled properly as to the safety hazards and that any
inadvertent contact with hazardous voltages is eliminated. To guard against risk of electrical shock during
open cover checks, do not touch any portion of the electrical circuits. Even when the power is off, capacitors
can retain an electrical charge. Use safety glasses during open cover checks to avoid personal injury by any
sudden failure of a component.
Due to filtering, the unit has high leakage current to the chassis. Therefore, it is essential to operate this unit
with a safety ground.
Some circuits are live even with the front panel switch turned off. Service, fuse verification, and
connection of wiring to the chassis must be accomplished at least five minutes after power has been
removed via external means; all circuits and/or terminals to be touched must be safety grounded to
the chassis.
After the unit has been operating for some time, the metal near the rear of the unit may be hot enough to
cause injury. Let the unit cool before handling.
Qualified service personnel need to be aware that some heat sinks are not at ground, but at high potential.
CAUTION!
380V 3-phase input power systems (4–wire) must have a neutral connection.
The neutral must not be switched. Apply neutral before phase voltage or
serious damage to the equipment may result.
iv

For safe operation, it is required that output power neutral be connected to chassis ground. The SW system
is shipped with a ground wire between power neutral and chassis ground.
These operating instructions form an integral part of the equipment and must be available to the operating
personnel at all times. All the safety instructions and advice notes are to be followed.
Neither Elgar, San Diego, California, USA, nor any of the subsidiary sales organizations can accept any
responsibility for personal, material or consequential injury, loss or damage that results from improper use of
the equipment and accessories.

GENERAL DESCRIPTION
Introduction
The Elgar SmartWaveTM Models SW 5250A, SW 3500A, and SW 1750A use trans-
formerless, direct coupled amplifiers and a true arbitrary waveform generator based
controller. This technology allows you to create, edit and generate complex waveforms
with high DC content for critical ATE and power line disturbance simulation testing.
The SmartWave can create complex waveforms with high DC content for simulating real
world power irregularities, including phase controlled sub-cycle or multi-cycle dropouts,
spikes, sags, surges, frequency excursions, plus frequency and voltage ramps
(sweeps). The unit can also generate clipped waveforms, harmonic distortion, high
current inrush, and other complex waveshapes.

1.5.2.9 Frequency Measurement
Frequencies are calculated based on output zero crossing time measurements. To

before the zero comparator.
Resolution: Frequency is displayed to 5 figures maximum; the leading zeros are
blanked. Displayed resolution is 0.01 Hz.

(32°F to 113°F).
1.5.2.10 Phase Measurement
Valid for phases A, B, and C relative to each other.
The phase of measured signals are calculated from timing measurements. The
reference is the negative to positive zero crossing of the internal reference (sync pulse)
signal. End of timing is the negative to positive crossing of the signals being measured
with respect to the internal reference. These timing measurements are used to calculate
the phase lead between the two phases being measured.
Resolution: ±1° (for outputs above 20 VRMS).
Accuracy: ±2°, 40 to 500 Hz; add ±2°/kHz above 500 Hz.
For sine wave, balanced resistive load, 10% to 100% of voltage measurement range.
All accuracies are specified for 0°C to 45°C (32°F to 113°F).
