The overcurrent sheet Overview: overcurrent protection sheet is designed to prevent the battery over-temperature caused by the charge due to overcharging, the battery over-temperature is a major concern of the battery pack design personnel. Lithium battery group overvoltage and overcurrent detection security protection circuit (including integrated circuits and semiconductor circuit as in the case of strong electrostatic discharge, temperature and short circuit failure.) But voltage protection circuit failure without temperature protection, the battery will overcharge or abuse charge generated too much heat, the battery rupture, leakage, smoke, or even burning.
Huaju Gong Division launched a new strip overcurrent protection piece, the resistance is low compared with previous products, the device can also play over-current protection and over-temperature protection, designed to meet the longer working hours in order to reduce the impedance of the battery pack, The requirements of the portable electronic product designs. Particularly suitable for the lithium ions and nickel-hydrogen is more sensitive to the temperature of the secondary (rechargeable) battery.
Battery over-current protection chip and battery pack inside the original battery in series, regardless of the temperature rise is caused by a short circuit caused by the overcharge, the device can play a protective role, no thermal fuse or bimetal circuit breaker. This entry like devices using nickel pin, small size and thin, can be welded directly to the original battery, save space and reduce installation costs
WMZ12A type PTC thermistor is mainly used [transformer (adapter) / primary coil / charger / digital multimeter / intelligent power meter / micro motor / transistor], overcurrent overheat protection, directly in series with the load circuit, in the line abnormal situation, it is able to automatically limit current or blocking current, and then restore the original state, commonly known as the "fuse" when troubleshooting.
Features:
Non-contact circuits and components overcurrent protection automatically limits
Automatically return to work after troubleshooting no noise no spark
Reliable, easy to use
3. Applications principle:
The WMZ12A type PTC thermistor in series in the power supply circuit, when the circuit is in the normal state flow through the PTC current less than rated current, PTC is in the normal state resistance is small, does not affect the electronic ballast (energy-saving lamps, transformer, multimeter) protection circuit work properly. When the circuit current is greater than the rated current, PTC suddenly fever, resistance surge up to the high-impedance state, thus limiting or blocking current protection circuit from damage. Current current back to normal, PTC also automatically revert to the low resistance state, the circuit to resume normal work.
The WMZ12A type PTC thermistors overcurrent protection applications in electronic ballasts (energy-saving lamps, transformer, multimeter), Nanjing, China giant advantage by virtue of its scientific research and technology and other aspects of the first to introduce a high withstand voltage (V ≥ 300VAC The) featuring WMZ12 products.(Metal Oxide Varistor)
