Specifications
Regulator Characteristics	Regulation	Less than ±1% of voltage setpoint from no load to full load
	Response time	Maximum of 4 milliseconds
	Voltage drift	Less than ±1% steady state
	Temperature drift	Less than ±1% for any 40 °C (104.0 °F) change over the operating temperature range
	Sensing voltage	Three-phase sensing is standard. Single phase sensing is available. The variable sensing range is 90 to 140 ACV for 50 and 60 Hz.
	Stability	The regulator responds to the main component of the sensed voltage and remains stable for total harmonic distortion of the generator output voltage, up to 20%.
Regulation	Volts/Hz characteristic	The characteristic is linearly proportional to frequency. 1 V/Hz characteristic can be selected by placing a jumper between terminals 6a and 8. 2 V/Hz characteristic can be selected by removing the jumper between terminals 6a and 8. These characteristics provide matched engine/generator performance for improved performance during block load application.
Regulation	Knee frequency	The knee frequency is adjustable from 45 Hz to 65 Hz. Refer to the Testing and Adjusting, "Knee Frequency - Adjust" for more information.
Adjustment Characteristics	Voltage adjustment range	The sensing voltage is adjustable from 90 to 140 V
	Reactive droop adjustment	The droop is adjustable from 0 to 10% at rated input current and 0.8 power factor. Either a 1 Ampere current transformer (CT) or a 5 Amperes CT with an output less than 10 VA may be used.
	External Voltage Adjust Rheostat	10 kOhm, 2 Watts
Protection	For Overexcitation	The protection shuts off the generator output when excitation voltage exceeds 90 VDC ± 5% for 30 seconds.
Power Characteristics	Power dissipation	Maximum 50 watts at rated output
	Input	100 to 280 VAC, single-phase on 50 Hz to 400 Hz applications 63 to 105 VAC, three-phase, on 50 Hz to 400 Hz permanent magnet (PMG) applications. Maximum of 1092 VA.
	Output (with a 240 VAC Input)	12 Amperes DC at 65 VDC maximum continuous 25 Amperes DC at 125 VDC forcing for 10 seconds
Temperature Range	Ambient operating	-40 °C (-40 °F) to +70 °C (+ 158 °F).
Temperature Range	Storage	-40 °C (-40 °F) to +70 °C (+ 158 °F).
Physical Specifications	Weight	1.1 kg (2.4 lb).
	Shock	Withstands up to 20 g's.
	Vibration	Withstands 0.5 g's at frequencies between 18 and 2000 Hz in three mutually perpendicular planes.
