Detailed Product Description

The integrate circuit we developed is a new integrate protection instrument which
has the functions including over-current protection, over-voltage protection and
alarm. 

In respect of over-current protection, it applies the semi-conductor technology.
When the current reaches the verge of the protection, the semi-conductor will conduct
immediately to introduce the current to the ground. 

This product has a rapid speed of over-voltage conduct so it can solve the coordination
problem of the primary protection and secondary protection. 

The alarm of the integrate circuit is solved by electronic circuit. When the semiconductor
works, the alarm signal will be sent out and be stopped when the conducting
stopped. And can be made into protection unit with self-healing function.

Specifications:
1) The upper-limit of voltage for over-voltage protection:                      

    a) 260 voltage rising rate: 100kV/s  
    b) 400 voltage rising rate: 1kV/s
2) The lower-limit of limit voltage for over-voltage protection: 190V
3) The bearing capability of surge current and power frequency current:
    a) Surge current 100A (peak current ) wave form 10/100 us 300 times, interval
time
        is 3 minutes
    b) Power frequency current 10A (effective value ) 50Hz, duration is 5 time one

        second, interval time is 3 minutes
4) Insulating resistance: more than 1000 ohm under standard atmosphere pressure
5) Over-current protection operate time: 350mA limit the current rate below 150mA
    in 5ms
6) Over-voltage, over-current protection meet the demand of YD/T694-1999
7) Alarm function: the modular with alarm output terminal. When the current arrives
    at 350 mA, (effective value), output alarm signals in 10 seconds, and the alarm
    signal will stop when the current disappear, and then self-heals
