厂家现货兼容利莱森玛 AVR R449 发电机配件 调压板 模块AVR R449

'技术参数：

电源输入：70-140VAC,(PMG,或辅助绕组，单，三相)

感应检测：90-480VAC

输出：DC 12A 125V

保护功能：内置低速，过励，LAM，功能

调 整 率：优于0.55

作用：

发电机在开机发电机，利用剩磁而发出很弱的电压，这个电压再回馈给发电机的励磁线圈而产生更强的磁场， 发出高的电压，这样慢慢电压就长高了。输出电压高于设定值时励磁板会控制输出的电压变低，励磁电流随之变小， 反之， 输出电压不控制或控制很小角度，电压会上升。

R449 voltage regulator of a sealed electronic devices, by adjusting the excitation current in order to stabilize the output voltage of the brushless generator.

Specifications

Normal AVR supply power: 2 auxiliary windings

Shunt supply: 150V - 50/60Hz

Rated overload current: 15A, 10s

Electrionic built-in(overload, shour circuit, and loss of sensing) prodtection: If Excitation current raises over 10 AMPS for more than 10 seconds, excitation current will drops automatically to about 1A.

To reset AVR protection, generator must be stopped(or by cutting supply voltage to the AVR).

Protection of power inputs by fuses F1

Voltage sensing: 5VA insulated transformer with input voltage taps at:

Terminals 0-110V=95-140V

Terminals 0-220V=170-260V

Terminals 0-380V=340-520V

Load current 7A

Overload current 15A, 10s
