E L GAR ONE YEAR WARRAN T Y
Elgar Electronics Corporation (hereinafter referred to as Elgar) warrants its products to be free from defects in
material and workmanship. This warranty is effective for one year from the date of shipment of the product to the
original purchaser. Liability of Elgar under this warranty shall exist provided that:
•the Buyer exposes the product to normal use and service and provides normal maintenance on the product;
•Elgar is promptly notified of defects by the Buyer and that notification occurs within the warranty period;
•the Buyer receives a Return Material Authorization (RMA) number from Elgar’s Repair Department prior to
the return of the product to Elgar for repair, phone 800-73-ELGAR (800-733-5427), ext. 2295;
•the Buyer returns the defective product in the original, or equivalent, shipping container;
•if, upon examination of such product by Elgar it is disclosed that, in fact, a defect in materials and/or
workmanship does exist, that the defect in the product was not caused by improper conditions, misuse,
or negligence; and,
•that Elgar QA seal and nameplates have not been altered or removed and the equipment has not been
repaired or modified by anyone other than Elgar authorized personnel.
This warranty is exclusive and in lieu of all other warranties, expressed or implied, including, but not limited to,

S AF E T Y NOT ICE
Before applying power to the system, verify that the TW Series unit is configured properly for the user’s
particular application.
WAR NI NG!
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 TW 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 no less than 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.
CAU T I ON !
380V 3-PHASE INPUT POWER SYSTEMS (4 WIRE) MUST HAVE A
NEUTRAL CONNECTION. (FOR UNITS BUILT BEFORE JUNE 1004: 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 TW 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 observed.
Neither Elgar Electronics Corporation, San Diego, California, USA, nor any of the subsidiary sales
organizations can accept any responsibility for personnel, material or consequential injury, loss or damage
that results from improper use of the equipment and accessories.

S E CT I ON 1 GE NE R AL DESCRIPTION
1.1 I NT R ODU CT I ON
The Elgar TrueWave™Series AC power source, models TW 3700 and TW 5550 use
transformerless, direct coupled amplifiers and a DSP-based sine wave controller for
testing a variety of complex electronics.
Figure 1-1 Elgar TrueWave AC Power Source (Rack Mount Version)
Programming is accomplished at the front panel or with a personal computer (PC).
The TrueWave communicates with the PC through a GPIB or RS-232 interface.
Programming commands are defined in the TW Programming Manual, Elgar Document
No. M161469-02.
One to three phase AC sine wave or DC output is specified by pushbutton/LED menu-
based control. Incremental and absolute voltage and current setpoints are available at
the TW front panel. The TW incorporates a hierarchical menu system to set system
parameters.
The TrueWave sources are true DC as well as AC power supplies. Up to 312 VRMS
are available in AC or AC+DC modes. Multi-phase models can be switched to single or
three-phased operation via the front panel or the GPIB.
A wide frequency range of DC or 40 Hz to 500 Hz is available for a broad array of
applications. Utilizing the latest in AC switch mode technology, the TW has less than
-60 dB of noise and ripple with total harmonic distortion (THD) of <0.5%. A crest factor
of 3.25 provides high peak-to-RMS current capability. An optional input power factor
correction (PFC) of .99 is also available.
