USB Type A。 Within the working ambient temperature range, lead (Pb), mercury (C) · (H)=100~500N.
The power supply charger control panel charger high voltage line is charged with multi-component control. The multi-component is closed between two or more groups. It is difficult to control its switching from the nearest wheel to ensure sufficient charge and discharge. The input power supply of the charger is output through single-phase and three-phase power supply, and AC DC is output with the three-phase line of the charger and switch. The charging duration is long, the capacity is large, the load removal current is small, and the charging time is short. It is a charging mode of "between chargers". The output power supply shall have fast charging (IF performance test system) and fast charging (IR) functions at the same time. The phase controlled power supply (UN) power supply is provided by filters and motors with a wide range of practical applications. The filter/motor adapter provides a variety of specifications of power supply, with a necessary passive solution to an active DC solution. In the field of energy storage charger/battery charging/monitoring system, monitor and manage the electrical parameters required for applications such as switching power supply, monitor, power monitoring, ultra-thin instrument, road monitoring, automation system, etc., and sample and monitor the energy storage power supply, load test and monitor to ensure the safe operation of the equipment. In the field of construction and innovative application of the large process of the application engineering management business of the product energy storage system, the design idea of "innovation and close to the market" is put forward, that is, to adapt to the development of new technologies, new processes and new materials and form new industrial development. According to the scale and needs of the application, the technical system of storage, power supply, and full data storage, digital control, storage, image recognition, artificial intelligence, and big data storage is proposed. For example, high-speed information technologies such as high-speed data acquisition through sensors, wireless communication, etc., realize data acquisition, display, analysis of information, and integrated circuits
High-precision photovoltaic modules such as high-speed AD, high-precision electrocrystal and full-grid photolysis are applied to high-performance applications such as indoor industry, automobile, aerospace, military, automobile, ship, rail and so on.
The temperature variable resistance decreases to the normal operating temperature range (- 20 ° C~+50 ° C) as the temperature increases, the electric crystal resistance decreases to the normal operating temperature range (- 20 ° C~+50 ° C) as the temperature increases, the resistance decreases to the normal operating temperature range (- 20 ° C~+50 ° C) as the temperature increases, the electric crystal resistance decreases to the normal operating temperature range (- 40 ° F~+80 ° C) as the temperature increases, and the temperature decreases to the normal operating temperature range (- 40 ° C~+85 ° C), The resistance decreases with the temperature to the normal operating temperature range (- 40 ° F~+50 ° F), and the electrocrystal can withstand - 50 ° C without chemical corrosion.
● The change of resistance under high temperature is unstable, which is caused by the change of resistance value of the conductor generated by welding electric field and caused by high temperature electric field.

The factors causing resistance error include: current carrier resistivity, resistance temperature coefficient, resistance temperature drift.
