current inrush limiter


Introduction

When you turn on an electrical equipment, the surge current can be restrained by a power NTC termistor connected in series with the power circuit. Because of the continuing action of currenttemperature of power NTC thermistor raising, the resistance will rapidly drop to a small value, the consumed power can be ignored. So it can't affect normal operating current. Therefore, using power NTC thermistor is a most effectively and most brief measure to restrain surge current, protecting electrical equipment from destruction.

 

Applications

◎Conversion power-supply, switch power-supply, ups power-supply

◎Electronic energy saving lamps, electronic ballast and all kinds of electric heater

◎All kinds of RT, display

◎ Bulb and other lighting lamps

 

Characteristics

 ◎Small size, strong power and strong capability of surge current protection.

◎ Fast response to surge current

◎ Big material constant (B value), Small remain resistance

 ◎Longevity of service. High reliability

◎ Integral series, extensive operating range
