Detailed description

Hawker AGV Safe series of lead-acid battery charger is a high-frequency switching power supply as the core, the main power converter using high-frequency high-permeability nanocrystalline transformers, microcomputer control of intelligent automatic charger.     

High-tech applications, improve the efficiency of the whole conversion. Products with high efficiency, energy saving significant features, compared to traditional charger energy saving 20% -30%.     

This series of microcomputer computer built-in a variety of battery charging program, accurate simulation of different types of battery charging curve. Choose a different charging program, can AGM, colloid, semi-colloidal and rich liquid water and other lead-acid batteries to charge.

The charging system consists of the charger and the charged battery to form a binary closed loop circuit. The dU / dt and dI / dt techniques are used to dynamically track the battery to accept the current. The microcomputer automatically determines the parameters of the on-line charging program according to the status of the battery, controls the output current and voltage Charging time, the charging current from the beginning to the end of the battery in the vicinity of the acceptable charge current curve, so that the battery almost no gas precipitation conditions. Not only save electricity, to achieve rapid charging, but also no damage to the battery to extend battery life. Current output is the pulse current mode, improve the battery charging capacity, reduce the concentration of polarization, electrochemical polarization, reduce gas generation. This is a very important way to reduce the battery temperature rise, reduce the battery plate deformation, reduce the gas flushing plate, reduce the active material off.

This series of charger with anti-battery reverse, the output short circuit, the output overload protection. Also has the function of automatic switch machine, can be connected to long-term input power. Need to charge, connect the battery pack, the charger work; no charge, disconnect the battery pack, the charger to stop working, the operation is very simple, user-friendly.

Hawker AGV Safe intelligent automatic lead-acid battery charger is a high reliability, high stability of the new energy-saving lead-acid battery charger.
