Application Notes:

• DGM-DB,DGM-JB series of low-voltage power distribution systems are widely used in AC 50~60Hz,220/380V supply power system of lines or equipment,mainly for weather ,traffic,postal electricity,computer networks,residential areas,railways and petrochemical and so on.play the function for the lightning over-voltage or line caused by transient over-voltage surge protection.

• DGM-DB,DGM-JB power lightning protection box under normal circumstances,the lightning protection module in a disconnected state,doesnt affect the normal operation,when the lines are struck by lightning over-voltage pulse appears insantaneous,the anti-ray module in a very short time over-voltage turn on circuit will discharge to the earth ,when the pulse after the disapperance of over-voltage ,mine went back to the disconnect module,and thus does not affect the electricity supply.

DB-type the main features:

• Intelligent lightning protection,and maintenance-free design
• Long-range distance warning letter and counting function of a lightning strike ,the largest data record 99 times
• Capacity for lightning-resistant,with instructions intelligent quantitative failure.
• Temperature control circuit technology used to avoid fires
