SAFETY NOTICE
Before applying power to the system, verify that the unit is properly configured for your application.
WARNING!
HAZARDOUS VOLTAGES IN EXCESS OF 280 VRMS, 600V PEAK MAY
BE PRESENT WHEN COVERS ARE REMOVED. THERE ARE NO USER
SERVICEABLE COMPONENTS IN THE UNIT.
Installation and service must be performed by qualified personnel who are aware of dealing with
attendant hazards.
Ensure that the AC power line ground is connected properly to the EW Series unit
input connector. 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.
Depending on your 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.
Due to filtering, the unit has leakage current to the chassis. Therefore, it is essential to operate this
unit with a safety ground.

1OVERVIEW
1.1 Introduction
The Elgar EW 3001 AC Power Source is a highly efficient AC Power Source providing sine
wave output of low distortion. The microprocessor-controlled sine wave oscillator generates
accurate and stable output voltage and frequency. The PWM (Pulse Width Modulation)
approach of the power stage provides full volt-ampere and current rating to loads. The EW
3001 supplies power up to 3000 VA.
The Elgar EW 3001 AC Power Source is considerably smaller, lighter and more efficient than
traditional power supplies with similar capability of outputting power.
This manual includes the specifications, installation procedures, operation and programming
instructions for the EW 3001 Power Source.
1.2 Features
Configuration
•Local operation through the keypad on front panel.
•Remote operation through GPIB or RS-232C interface.
•Protection against over power, over current, over temperature, under voltage,
fan failure, and open circuit.
•Temperature-controlled fan speed.
•Built-in output isolation relays.
Input/Output
•Selective full scale output: 150V/300V Auto.
•Remote control by analog voltage reference.
•Measurement of V, F, PF, CF, I, P.
•Programmable limit of output Irms.
