CW Series

800-2500VA PROGRAMMABLE AC POWER SERIES

Product Overview

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 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

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 0-5V 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

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.
