Product Overview
Manual CW Features and Benefits
The Continuous Wave (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 RS232 control. Both series have three power levels,
800VA, 1250VA and 2500VA. The 800 and 1250VA models are 2RU high and allow
the unit under test to be connected to the front or rear panel. The 2500VA model
is 3RU high with rear panel output connections. All models can be operated in a
bench-top or rack-mount configuration.
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 0-5V 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 factory
supplied optional cables. Current shutdown or fold-back modes can be selected
from rear panel switch.
Programmable CW Features and Benefits
The front panels have two bright four digit, seven segment displays. Power
Factors Corrected (PFC) universal input voltage allows maximum to be delivered
from an AC outlet without user selecting the range. Fully rated current is delivered
for either output voltage range of 135VAC or 270VAC over a standard frequency
range of 45-500Hz. Custom output voltage are available (consult Powerbox for
details). Both series can be operated in parallel or three phase configurations.
A separate output on/off switch controls power to the load. Remote voltage sense
is standard. Transformer coupled output is protected against over-voltage 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 are
CE marked.
Product Applications
The Continuous Wave is designed for testing single or poly-phase electronics. The
CW is well suited for applications requiring a cost-effective low profile AC source.
APPLICATION INCLUDE:
• Testing for real world sine wave power conditions
• 400Hz testing for avionics equipment (50/60Hz margin testing)
• Ballast testing (Components testing)
• Power supply testing for AC to DC converters

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 operations. This menu also allows
setting current shutdown of fold-back modes. Remote IEEE-488.2 and RS232
control interfaces are standard. LEDs indicate high and low range output voltage,
measure a program mode, voltage a current mode generation and output on. Also
indicate menu/status, remote control, lockout and fault conditions. Digital Signal
Processing (DSP) based measurements include voltage, current (amperes, peak
amperes, crest factors), power (watts, VA and power factor) and frequency.
