Atec Elgar-CW2501P-112 - Manual

858.458.0223 [email protected]
The Elgar ContinuousWave (CW) Series of AC
power sources provides clean single phase power
at an impressive price/performance ratio. These
compact switch mode sources come in two series,
manual (CW-M) or programmable (CW-P) with
standard IEEE-488.2 and RS-232 control. Both
series have three power levels, 800 VA, 1250 VA
and 2500 VA. The 800 and 1250 VA models are
2U (3.5”) high and allow the unit under test to be
connected to the front or rear panel. The 2500 VA
model is 3U (5.25”) high with rear panel output
connections. All models can be operated in a
benchtop or rackmount configuration.
The front panels have two bright four digit, seven
segment displays. Power Factor Corrected (PFC)
universal input voltage allows maximum power
to be delivered from an AC outlet without the
user selecting the range. Fully rated current is
delivered for either output voltage range of 135
VAC or 270 VAC over a standard frequency range
of 45 to 500 Hz. Both series can be paralleled to
provide extra power.
A separate output-on switch controls power
to the load. Remote voltage sense is standard.
Transformer coupled output is protected against
overvoltage and overcurrent. The unit is also
protected against over temperature conditions.
A two-speed fan results in quieter operation at
lower power levels. All models are CE marked.
Applications for the CW Series include:
•Testing for real world sine wave power
conditions
•400 Hz testing for avionics equipment
•50/60 Hz margin testing
•Ballast testing
•Components testing
•Power supply testing for AC to DC converters
Manual CW Features And Benefits
The manual series front panel knobs (10 turn
potentiometers) allow quick adjustment of
voltage, current and frequency settings. Frequency
and voltage can be programmed remotely using a
0 to 5V analog signal. LED’s indicate: output-on,
voltage or current mode operation, fault and slave
modes. Models can also be paralleled in the field
or configured for three phase operation using
a factory supplied cable. Current shutdown or
foldback modes can be selected from a rear panel
switch.
Programmable CW Features And Benefits
Front panel encoder knobs allow programming
of voltage, current and frequency settings.
Programmed or measured values can be viewed
on the two LED displays through push button
selection. Menu push buttons enable setting
system configuration including parallel or three
phase operation. This menu also allows setting
current shutdown or foldback modes. Remote
IEEE-488.2 and RS-232 control interfaces are
standard. LEDs indicate: high or low range output
voltage, measure or program mode, voltage or
current mode operation and output-on. LED’s
indicate menu/status, remote control, lockout and
fault conditions. Digital Signal Processing (DSP)
based measurements include voltage, current
(amperes, peak amperes, crest factor), power
(watts, VA and power factor) and frequency.
