Elgar CW801M, CW801P, CW1251M, CW1251P, CW2501M, CW2501P AC Power Sources

Additional Product Information

The Elgar Continuous Wave (CW) 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. The CW Series 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).

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.

Manual CW Features (CW-M Models)
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. LEDs 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.

Programmable CW Features (CW-P Models)
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. LEDs 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.
