    Elgar ContinuousWave (CW) Series
    End of Life (EOL) June 2019.  Please see newest Replacement product, Asterion AC here.

    The 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 or RS-232 control, available at 2500 VA. 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.

    Features And Benefits
    Key Features

    • Wide range PFC Input
    • Low THD and AC noise
    • Advanced Measurement Available
    • Field Parallel Configurable
    • Multiple Units Configurable for Poly-Phase Operation

    The ContinousWave (CW) is designed for testing single or polyphase electronics. The CW is well suited for applications requiring a cost-effective low profile AC source.

    Applications 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.
