   ELGAR CW1251P   Description / Specification:   Spec Sheet 
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.

Crest Factor
Crest factor or peak-to-average ratio (PAR) is a measurement of a waveform, calculated from the peak amplitude of the waveform divided by the RMS value of the waveform

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Phase Noise
Phase noise is the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities. Phase noise (L(f)) is typically expressed in units of dBc/Hz, representing the noise power relative to the carrier contained in a 1 Hz bandwidth centered at a certain offsets from the carrier.

Sensitivity
Sensitivity is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria.
