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
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

Feature	If you're looking for a reliable solution to regulate voltage on your Leroy Somer generator, look no further than the R120 automatic voltage regulator (AVR). Designed to work seamlessly with the TAL040, TAL042, and TAL044 models, the R120 is the same exact AVR as Leroy Somer's AEM230RE005L and 4969966 voltage regulators. At its core, the R120 senses inputs of 277 VAC +/- 10% for a 1-phase system or 415 VAC line-to-line +/- 10% for a 3-phase, 2-line sensing system. Using SMD resistors for sensing and control, the AVR determines the true average of the line-to-line waveform to ensure accuracy and reliability. As for input power, the R120 requires a voltage of 277 VAC rms +/- 10% and a frequency of 50/60 Hz. Conversely, the output power provides a voltage of 95 VDC for 240 VAC input and a current of 4A DC or 6A for 30 seconds (if field resistance allows). The R120 can operate in a wide temperature range, from -20ºC to +70ºC for operation and -40ºC to +80ºC for storage. And with a voltage setting that's adjustable to within a +/- 10% range of the rated voltage and a stability setting for correct transient responses, you can be sure that your Leroy Somer generator is running at optimal levels. Lastly, the R120 features an under frequency roll-off setting that's available below 46Hz for 50Hz systems and below 56Hz for 60Hz systems. Its voltage build-up is 2 volts (L-N) and its voltage regulation is +/- 1% at the AVR terminals with a THC Thermal drift of +/- R120. With the R120, you'll never have to worry about voltage fluctuations affecting your Leroy Somer generator's performance. It's a high-quality AVR that promises dependability and precision with every use.
