(10 ohms min when input volts is less than 175 ac)
REGULATION
+/- 1.0% (see note 2)
THERMAL DRIFT
0.03% per deg. C change in AVR ambient (see note 3)
TYPICAL SYSTEM RESPONSE
AVR response: 20 ms
Filed current to 90%: 80 ms
Machine Volts to 97%: 300 ms
EXTERNAL VOLTAGE ADJUSTMENT

Input resistance 1k ohm
QUADRATURE DROOP INPUT
10 ohms burden
Max. Sensitivity: 0.07 A for 5% droop 0PF
Max. Input: 0.33 A
OVER EXCITATION PROTECTION
Set point 75 V dc
Time delay 10-15 seconds (fixed)
ENVIRONMENTAL
Vibration: 20-100 Hz 50mm/sec
100Hz -2kHz 3.3g
Operating temperature: -40 to +70o C (note 7)
Relative Humidity: 0-70o C 95% (note 8)
Storage temperature: -55 to +80o C
Note:
1. De-rate by 12% if mounted in 'portrait' orientation.
2. With 4% engine governing.
3. After 2 minutes .
4. Generator de-rate may apply. Check with factory .
5. Factory set, semi-sealed, jumper selectable .
6. Any device connected to the analogue input must be fully
floating (galvanically isolated from ground), with an
insulation strength of 500V ac .
7. De-rate output current by 5% per degree C above 60C.
8. Non condensing .
