Table 1
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).    
Power dissipation     5 watts at idle, 55 watts at rated output.    
Shock     Withstands up to 20 g's.    
Vibration     Withstands 4.5 g's at frequencies between 18 and 2000 Hz in three mutually perpendicular planes.    
Salt spray     Meets MIL-STD-810C, method 509.1.    
Sealing     Withstands up to
35 kPa (5.08 psi).    
Weight    
5 kg (11 lb).    
Electromagnetic compatibility     Meets 89/336/EEC Electromagnetic Compatibility Directive.    
Power supply     24 6 volt DC power supply required (0.5 amp).
