Advantages Lee Sheng Electronics Factory to introduce you to the battery charger: 6, high reliability: The charger uses advanced circuit design, high quality military grade and industrial grade components manufactured in strict accordance with the ISO9001 international quality management system standard for production and management, low failure rate, high reliability and long service life. 7, multiple protection features, high reliability, with overheat protection, output short circuit protection, output reverse polarity protection, output overvoltage protection, such as multiple functions, effectively prevent misuse and damage. When the battery voltage is low (charger can be set toy wholesaler, the circuit preset 9V below), the charger works in a small current to maintain the charge state, the working principle is U1C⑨ foot (in-phase side) potential is lower than ⑧ feet (inverting terminal), U1C output low toys charger, T4 off. U1D 11 feet potential of about 0.18V. At this point the charging current of about 250mA (constant current circuit by R14, U1D, T1B surrounding peripheral circuits 12v charger toys, constant self-analysis principles Readers).
