Lilaisongma R448AVR

Voltage regulation rate <± 0.5%

With LAM function to increase the stability at the moment of loading

Select 50 / 60Hz by cable

With low frequency protection and over-excitation current limit function

Choice of single-phase or three-phase voltage detection

With slow start function to stabilize initial voltage

Stable adjustment with two stages of response time

Voltage: terminal 0-110V = 95 ~ 140V terminal 0-220V = 170 ~ 260V terminal 0-380V = 340 ~ 520V
Frequency: 50 / 60Hz with cable selection

Power input voltage: 40 ~ 150VAC three-phase

Magnetic field output voltage: Max 160VDC @ 120VAC Power current: Max 10A

Voltage regulation <± 0.5% (with engine speed fluctuation within 4%)

The voltage is established based on the residual magnetic voltage of the AVR input terminal.

External voltage adjustment ± 10% @ 1KΩ

Slow voltage settling time The residual magnetic voltage at the AVR input terminal needs to be above 5VAC

Lilaisongma R250AVR

SHUNT excitation system
SHUNT field motors are driven by R250 voltage regulators.
The regulator controls the excitation system based on the output voltage of the motor.
The SHUNT excitation motor has no short-circuit capacity and is simple in design.
Specifications:
Voltage adjustment: ± 0.5% supply range / voltage detection: 85-139 volts (50/60 Hz)
The fast response time of the transient voltage ± 20% variation is 500 milliseconds.
Voltage setting P1.
Stability setting P2.
8A fuse provides protection and slow-moving (supports 10A, 10 seconds).

Lilaisongma R438AVR

R438 can use APER or PMG excitation system. The R438 circuit provides closed-loop control of the generator output voltage by adjusting the excitation current.
Specifications:
Voltage adjustment: ± 0.5% Short-circuit capacity: Rated 3Xl, 10 seconds (AREP or PMG excitation system)
Voltage readout:
95 to 140 volts (50/60 Hz);
170 to 260 volts (50/60 Hz);
340 to 520 volts (50/60 Hz)
Response time:
Normal time ± 20% voltage adjustment takes 1 second;
Quick response ± 20% voltage adjustment takes 0.3 seconds.
Remote voltage adjustment range: ± 5%
