Specifications | |
---|---|
Regulation | 0.25% from no load to full load |
Regulator temperature drift | Less than 0.5% for any |
Configurable Volts/Hz characteristic | Two slope ranges adjustable from 1 to 10 V/Hz. See the Regulation Characteristic Illustration. |
Regulator response time | Maximum of 10 milliseconds. |
Regulator sensing | True RMS 3-phase sensing is standard. Single phase sensing is available. Variable sense range: 90 to 600 volts. |
Regulator stability | The regulator responds to the fundamental component of the sensed voltage and remains stable for total harmonic distortion of the generator output voltage waveform, up to 20%. |
