ELGAR CW1251P 0-135/270 Vrms, 4.7/9.4 ARMS Continuous Wave AC Power Source

The Elgar CW 1251P ContinuousWave (CW) AC power sources provides clean single phase power. The front panel has 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. It 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. 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. Specifications. Power: 1250 VA. Voltage ranges: 0 to 135 Vrms, 0 to 270 Vrms, user selectable. Voltage Accuracy: (>5VAC) ±0.1% of range <100 Hz, ± 0.2% of range >100 Hz. Resolution: 0.1 Vrms. Total harmonic distortion: 0.25% typical <100Hz add 0.5%/100 Hz above 100 Hz. AC noise level (typical): <50 mVRMS. Amplitude stability: ±0.05% of full scale. Load regulation: ±0.1% of full scale voltage for a full resistive load to no load (<10 mVRMS typical, measured at point of sense). Line regulation: ±0.1% of full scale voltage for a ±10% line change from nominal line voltage (<5 mVRMS typical, measured at point of sense). Current: 9.4 ARMS (135 VAC Range), 4.7 ARMS (270 VAC Range). Current Accuracy ± 0.5% typical. Current Resolution: 0.01 ARMS. Frequency range: 45 to 500 Hz, 45 to 1000 Hz (option). Frequency Accuracy: ±0.02% typical. Frequency Resolution: 0.1 Hz, 0.01 Hz for remote programming.

*This is a Web introductory price for one calibration of the ELGAR CW1251P. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
