Specifications     | |
---|---|
Regulation     | 0.25% from no load to full load.     |
Regulator temperature drift     | Less than 0.5% for any 40 °C (72 °F) change over the ambient operating temperature range.     |
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%.     |
Telephone influence factor (TIF)     | Less than 50. Complies with MIL STD 461C Part 9 and VDE 0875 level N.     |
Fine voltage adjust range     | ± 10% of regulator sensing voltage.     |
Regulator voltage gain (Line loss compensation)     | Adjustable from 0 to 10%.     |
Fault detection and identification     | Diagnostics identify operation outside of programmed limits. Specific fault information is available even after the unit has been powered down.     |
Regulator start-up voltage     | Meets ISO8325-3 class G2 specifications.     |
Harmonic tolerance     | The digital voltage regulator maintains precise control of the generator output with up to 20% harmonic distortion in the generator output voltage.     |
Reactive droop adjustment     | Adjustable from 0 to 10%.     |
Overexcitation protection     | Shuts off generator output when excitation current exceeds normal operating currents for 15 seconds or instantaneous shutoff if output is shorted.     |
Ambient operating temperature     | −40 °C (−40 °F) to +70 °C (+ 158 °F).     |
Storage temperature range     | −40 °C (−40 °F) to +85 °C (+ 185 °F).     |
