> > working performance and characteristics
1, zero power resistance low: since after the fuse
itself, low impedance during normal working less power consumption, lower surface temperature, 2, over-current protection speed: from complex fuse because of its own material properties, the flow state response speed than other over-current protection units much faster;
3, self-locking operation: from complex fuse in over-current and overtemperature protection condition, the narrowest of current locked in the high impedance condition, only cut off power supply or over-current receding and will restore low impedance condition, 4, automatic reset: from complex fuse in on the over-current, overtemperature protection after (troubleshooting self reset, no failure safety;
5, resistant to large current: from complex fuse has excellent resistance to large current capacity, some specifications can withstand 100A current shock;
6, since after short time: the complex fuse in over-current and overtemperature condition disappear after a few seconds, the temperature drop quickly, components can recover soon to its low impedance condition.
> > application range and selection method
Since after the fuse widely applied in all kinds of electric equipment, electronic products, communication system equipment, household appliance and engineering control systems, such as: computers and peripherals, measuring instruments, fire prevention, equipment, automobile electronic products, pabx, mobile battery, audio equipment, electric fan, air conditioner, refrigerator, speakers, transformers, motors, micro-motor and batteries, power supplies, charger, energy-saving lamps, electronic ballast and halogen lamps, etc.
Please click below the correct choice of the complex method fuse:
1, determine equipment on a line of work on average current (I) and the maximum voltage (Vmax);
2, uncertain environment temperature range, according to the normal and fold reduction rate computation normal current (Ih) : normal current (Ih) = average current voting environment temperature reduction rate (reference by folding table 1);
3, determine the largest equipment line fault current (Imax);
4, Vmax, Ih value, according to the product type and installation choice a selfadaptive complex fuse series, 5, according to step 4 selected products series, in the corresponding specification table selected within specific models (note: selected models of Vmax, Imax, Ih must is equal to or greater than in a circuit, Vmax Imax and step 2 calculated Ih) values.
* lines as to normal temperature resistance and over current protection time required, in the above methods selected corresponding series, on the basis of normal temperature resistance selected again according to corresponding component;
* as users have special requirements, in "specification" no corresponding element is available, please contact our company, we will soon you according to the request to the specific development.
