effect of discharge feedback (75%), heat is small, so as to achieve the purpose of energy

saving and cost reduction for users;

Constant Current to Constant Voltage Charging Safely and Smoothly, The voltage and

current of the device are connected in a four-wire system, and the voltage and current loops

are independently designed to ensure a safe and smooth transition during the constant

current to constant voltage charging process to avoid damage to the battery due to spikes;

voltage and discharging voltage are all calibrated with high precision by Agilent to ensure that

the accuracy of current and voltage is within 0.5‰;

Excellent Heat Dissipation Performance, Unique air duct design, through forced air

cooling to reduce the impact of high temperature on equipment performance. Adopt dual-fan

mode, perform forced air cooling on the power cooling module, and use thermal imager for

thermal simulation test to ensure that the radiator works within a reasonable temperature

range;

The Channel is Detachable, Various channels in the same box can be freely connected in

parallel according to needs to be compatible with multiple types of battery tests, give full play

to the multiple functions of the equipment, and save equipment costs for customers;

The Built-in Temperature of The Device, Each channel can be customized according to

needs, with one main temperature without external auxiliary temperature (with multiple

channels, the temperature needs external auxiliary temperature), Monitor the battery

temperature in real time, so as to monitor and protect the normal safety test of the battery

according to the temperature change;

Single Box Power Supply, Each cabinet of the whole cabinet is powered independently to

ensure the stability and safety of the power supply of the whole cabinet;

Power independent, To ensure that the output of the circuit is uniform during the working



process of the power supply, and there is no protection problem;

The Clamp is Flexible and Adjustable, It can be compatible with a variety of sizes of

batteries, truly a multi-purpose one, and maximize the use value.
