*Wide range PFC Input

The Elgar 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 ａnd RS-232 control. Both series have three power levels, 800 VA, 1250 VA ａnd 2500 VA. The 800 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 bench 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

Transtormer coupled output is protected against overvoltage ａnd overcurrent. The unit is also protected against over temperature conditions. two-speed fan results in quieter operation at lower power levels. All models are CE marked.

Applications for the CW Series include:

*Testing for real world sine wave power conditions

*400 Hz testing for avionics equipment

*50/60 Hz margin testing

* oBallast 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 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. 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.
