PRODUCT INFORMATION

R120 AVR- AUTOMATIC VOLTAGE REGULATOR REPLACE FOR BRUSHLESS DIESEL GENERATOR

 

 

DESCRIPTION:

AVR R120 is a half-wave phase controlled thyristor type automatic voltage regulator and forms part of the excitation system for a brushless generator. In addition to regulating the generator voltage, the AVR circuitry includes under speed and sensing loss protection to ensure safe, reliable control of the generator. Positive voltage build up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR. Which is linked with the main stator windings and the exciter field windings to offer closed loop control of the output voltage with load regulations of +/-1.5%

SPECIFICATION:
Sensing input: voltage: 277V AC ±10 % for 1-phase, 415V AC line-to-lint ±10% for 3-phase, 2-line sensing. The AVR senses the true average of the line-to-line waveform. Use the resistor (SM ) network for trouble-free sensing and control of sensed voltage/regulation

INPUT POWER:
Voltage: 277V AC rms=10%
Frequency: 50/60Hz

OUTPUT POWER:
Voltage: 27 V AC rms=10%
Frequency: 50/60Hz
Voltage: 95V DC for 240V AC input
Current: 4A 6A for 30 sec ( when allowed by the field resistance)

Voltage setting: ±10% of rated range
Stability setting: adjusted to obtain a correct transient, response in steady state
Under frequency roll-off setting: available below 46Hz for 50Hz and below 56Hz for 60Hz
Voltage build-up: 2V (L-N)
Voltage regulation: ±1% at the AVR terminal with a THC <5%
Response time: less than 50ms
Over excitation protection: 10V DC to 85V DC, set point: 60V DC
Protection fuse: 4A, 240V AC

PACKAGE LIST:
1 x Automatic Voltage Regulator
