Excitation Plate of Electric Generator

1 sku

Excitation Plate of Electric Generator

Technical parameters

1. Type: PC11;
2. Convert alternating voltage produced by generator to direct voltage required by generator excitor. This plate includes two rectified current, one is bridge rectifier, the other is silicon controlled rectifier, the two rectifiers can automatic transfer;
3. When generator is launched, because the remannence voltage of the generator is too low, the bridge rectifier curcuit can built generator voltage immediately to, external battery and attachments are not needed;
4. When generator voltage arises to a certain level, the silicon controlled rectifier control curcuit will automatically replace the bridge rectifier cercuit to ensure the safety and reliability of the generator excitation curcuit;
5. When generator functions well, it will form an inner ring controlled by closed-loop with AC module to maintain a 600V AC voltage for the generator;
6. When a sudden load change of the generation set occurs, it will form a outer ring controlled by closed circuit with AC module to steadily adjust the exciting voltage, the voltage will be recovered to its set value in a short time;
7. Excitation output:0110 DC voltage signal.
