Installation and use instructions
4342CH - 3.2010 / A
A.V.R R450
Technical characteristics 3.1
- Electrical Characteristics
- the largest supply of power: 150V-50/60Hz
- rated load current: 10s - 10A
- Electrical Protection: when a short circuit occurs, the excitation current in 10 seconds will be reduced to less than 1A.
When the reference voltage is lost, the excitation current is "AREP/SHUNT" "
System in a second lower to 1A below; in the "PMG" system after 10 seconds to lower to 1A.
- fuse:
- F1 connected to the X1 line, F2 connected to the Z2 line. 10A; slow -250V
Voltage detection: R450: 0-110 terminal v = 95 to 140 V 0-220 terminal v = 170 to 260 V 0-380 terminal v = 340 528V R450M & T: low range: < 320v high range: > 320v for other voltage, achieved through the use of transformer.
Voltage regulation accuracy: + 0.5%
- current detection (and running):
From S1, S2 input, using a C.T. < 2.5 CL1 VA, the auxiliary winding current 1A or 5A of the current transformer.
- configuration
- setting
The regulation range of the voltage potential regulator P1 is shown in the following table:
50HZ or 60HZ
The maximum voltage high range Un less than 530V in the range of Un = 252V Un = 140V low range
The allowable adjustment range is: + 5%, when the voltage to be adjusted exceeds these limits, please check whether the generator is satisfied with the power meter.
3.2.1.2 - orthogonal modulation
Quadrature adjustment to adjust through the potentiometer P4, it needs to meet
The following range: 0 ~ 8%: when the PF=0.8, excitation voltage 400V; 0 ~ 14%: when the PF=0.8, excitation voltage 240V; 0 ~ 8%: when the excitation voltage 110V, and the reference voltage is equipped with a voltage reducing transformer. The potentiometer P4 belongs to nonlinear response, when the secondary winding current is 1a of the transformer is connected and effective adjustment range from the beginning of the second 1 / 3 (P4); when the secondary winding current is 5a of the transformer is connected and effective adjustment range from the beginning of the first 1 / 3 (P4).
Thus, when the auxiliary winding current is 5A, the range of adjustment is larger, so the initial position of the potentiometer P4 must be located at the first 1/4 (counter clockwise), and then gradually increase.
CT must access the circuit
The 3.2.1.3 stability regulator is controlled by the potentiometer P2, and the switch is selected.
The motor is determined according to the type and response time (see section 3.2.3)
3.2.1.4 - exciting current limit value of the excitation current limit by the potentiometer P3 to control.
The steady state excitation current limit threshold is set to 110% of the rated field current by the potentiometer. This adjustment process is completed in the rated load test by the operator to turn the potentiometer P3.

Technical characteristics of R450 pressure regulator
The 9 limit threshold
The threshold limit must be between 1 to 5.5A can be adjusted
When the excitation current exceeds this value, counter is activated, its speed as one count per second, lasts 90 seconds, current will reduced to rated excitation current value. If, during this period, the excitation current drops below the threshold, the counter is at the same rate of decline.
In short circuit, the operation mode between 3In and 6In: the limit current of the exciting current is 2.9 times of the exciting current threshold. At this time, the excitation current in 10 seconds (always at the peak of the excitation) will be reduced to 0.5A to 0.7A.
Under any operating conditions the maximum excitation current must be limited to 9A + 0.5A.
Indicator light: green LED lamp:
Bright: when the excitation current is less than the threshold value of the continuous work, or the excitation current is less than the limiting current, light is bright, said at the AVR in normal working condition.
- off: when the excitation current reaches the limit set, or when the excitation current is reduced to 0.5A to 0.7A (shutdown).
- blink: when the excitation counter decrement.
Red LED light: - Liang: when the excitation current higher than the continuous working threshold for 90 seconds, the excitation current will be reduced to the threshold, the red LED light, which is used to set the limit of the excitation current
- out: when the excitation current in the setting of the threshold below, the red LED lights.
- Flash: when the excitation current in the normal threshold less than 90 seconds, the LED light flashes red.
When the green LED lights out - flashing: get the reference voltage, the "AREP/SHUNT" system less than 1 second in the "PMG" system in less than 10 seconds.
- bright: the excitation current is equal to 0.5A to 0.7A (shutdown).
