It has the advantages of simple operation and safe discharge.
The equipment has perfect functions:
●Discharge is carried out on high-power resistors, causing no pollution to the power grid.
●It adopts constant-current discharge technology, and the current remains constant throughout the discharge process.
●It has the functions of automatic detection, delayed start, soft start and soft shutdown.
●It has the functions of fault protection and alarm for open circuit, reverse connection, overload, overheating and so on.
●It has the function of simultaneously controlling the discharge termination point with multiple parameters such as voltage, time and capacity to ensure the safety of discharge.
●It has an automatic gear shifting function: For users with a wide range of discharge voltage, this equipment is equipped with multiple output gears and can automatically realize the gear shifting function according to the voltage level of the connected battery by the user without the need for manual operation.
●The LCD displays the discharge parameters and fault information in real time.
●High-brightness LEDs indicate the operating status of the equipment and fault alarms.
●For the parameters set by the user, the system can remember them for a long time and will not lose them even in the event of a power outage. After the discharge parameters are set for the first time, if the same battery is to be discharged later, there is no need to reset them.
●Users can set or modify all parameters online during the discharge work process.
