      SAME EXACT AVR AS:
      Leroy Somer Voltage Regulator AEM230RE005
      Leroy Somer Voltage Regulator 4969966

      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 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
