Over-Voltage Over-Current Integrate Circuit
Features:1) This product has a rapid speed of over-voltage conduct so it cansolve the coordination problem of the primary protection andsecondary protection2) The alarm of the integrate circuit is solved by electronic circuit3) When the semiconductor works, the alarm signal will be sent out andbe stopped when the conducting stopped4) Can be made into protection unit with whole self-healing functionTechnical parameters:1) Upper-limit of voltage for over-voltage protection:a) 260V (voltage rising rate 100kV/s)b) 400V (voltage rising rate 1kV/s)2) Lower-limit of voltage for over-voltage protection: 190V3) Bearing capability of surge current and power frequency current:a) Surge current: 100A (peak current) waveform 10/100μs 300 times,interval time is 3 minutesb) Power frequency current: 10A (effective value) 50Hz duration is5 time one second, interval time is 3 minutes4) Insulating resistance: ≥1,000MΩ under standard atmosphere pressure5) Over-current protection time: 350mA, limit the current rate below150mA in 5ms6) Over-voltage over-current protection meet the demand of YD/T694-19997) Alarm function: the modular with alarm output terminal; when the currentarrives at 350mA, (effective value), output alarm signals in 10 seconds,and the alarm signal will stop when the current disappear, and thenself-heals
