CW Applications
The Continuous Wave Series of AC
power sources provides clean single phase power at an impressive
price/performance ratio. It is
designed for testing single or
polyphase electronics and has
extensive programming features.
Programmable AC Power Sources
he ContinuousWave (CW) Series of
TAC 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
the manual and programmable models
can be field configured for three phase
operation or used in parallel (including
parallel - three phase) with optional
factory supplied cables. Both series
have three power levels, 800 VA,
1250 VA and 2500 A. The 800 VA 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. The
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 (45 to 1000 Hz
with option H, CW-P only). Custom
output voltages are available (consult
factory for details).
A separate output-on/off switch
controls power to the load. Remote
voltage sense is standard. Transformer
coupled output is protected against
overvoltage and over-current. The unit
is also protected against over-temperature conditions. A two-speed fan
results in quieter operation at lower
power levels. All models have the CE
Mark. UL Models available.

Programmable CW Features
The manual series front panel knobs
(10 turn potentiometers) allow quick
adjustment of voltage, current and
frequency settings. Frequency and voltage can also 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 an optional
factory supplied cable. Current shutdown or foldback modes can be
selected from a rear panel switch.
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. LED’s
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.
