Description: 
Automatic Voltage Regulator AVR 

Specification:
Sensing input:
- Voltage: 277 VAC ± 10% for 1-phase,
415 VAC line-to-line ± 10% for 3-phase,
2-line sensing. The AVR senses the true
average of the line-to-line waveform. Use
the resistor (SMD) network for trouble-free
Sensing and control of sensed voltage/regulation.
Input power:
- Voltage: 277 VAC rms ± 10%
- Frequency: 50/60 Hz
Output power:
-Voltage: 95 VDC for 240 VAC Input
-Current:
4 A DC
6 A for 30 sec. (when allowed by the field resistance)
Operating temperature: -20ºC to +70ºC
Storage temperature: -40ºC to +80ºC
Voltage setting: min ± 10% of rated voltage.
Stability setting: can be adjusted to obtain
a correct transient response in a steady state.
Under frequency roll-off setting: available
Below 46 Hz for 50 Hz and below 56 Hz for 60 Hz.
Voltage build-up: 2 Volts (L-N)
Voltage regulation: ± 1% at the AVR
terminals with a THC <5%.
Thermal drift: ± 1% for 30ºC change in temperature.
Response time: less than 50 ms.
Closed loop response: typically 0.5 sec to recover 98% of the defined voltage for a field forcing ratio of 1:2.
Sensing loss protection: the voltage
should disappear when the sensing circuit is open.
Overexcitation protection: 10 VDC to 85 VDC.
Set point: 60 VDC
Protection fuse: 4 A, 240 VAC.
Potentiometer sealing: except for the
V-trim potentiometer, all potentiometers are sealed.
Frequency roll-off indicator: LED provided (UF).
Sensing loss indicator: LED provided (SL).
Overexcitation indicator: LED provided (OE).
Protection on the devices: suitable R-C
snubber to be provided for the device used
to protect against voltage surges.
Potting/Encapsulation details: the
components on the AVR should be
completely encapsulated with suitable PU
resin compound to absorb transients/
vibrations during operation.
Alternator excitation details: (typical)
-Full load:
Excitation voltage: 40 to 50 V
Excitation current: 2.5 to 4.0 A
