HDFD DC Load Bank 480V 80A


General information

HDFD Battery Discharge Tester can be used as the discharge load in the battery off-line state to realize the constant discharge at the set value by regulating continuously the discharge current. When discharging, the tester will automatically stop discharging when the voltage on the battery group terminal or the cell falls to the set lower limit value, or when the set discharging time is out, or when it reaches the set discharging capacity. Battery Discharge Tester can records all valuable and continuous real-time data during the discharge process.
This tester system is simple, safe and accurate for monitoring voltage of cells adopting wireless connection.
 
Features

● PTC ceramic resistor is adopted to avoid the red heat phenomenon for a safer discharge process .
● PC software can record and analyze total voltage, discharge current ,cell voltage and other data , generate the data report . it can virtually reflect battery serious performance curve, diagram and report for printing and searching .
● Connected with USB interface,the data of the discharge process can be record to U disk and transformed to PC by U disk . PC data manage software can analyze the discharge process and generate the corresponding data for more convenient storage .
● Intelligent SCM ARM control, 7inch 1024*600 LCD screen , capacitive touch operation, built in English menu, simple and clear operation menu.
●Automatic self-protection stop function, over-heat protection ,over voltage protection , over current protection and reverse connection protection ,alarm prompt is displayed on the screen once it appears any issue, air circuit breaker automatically cut off .
● It can perform on-line compensated charge/discharge, and can also carry on discharge test for on-line working storage battery by connection external current clamp sensor,which is convenient for measurement work. The function is suitable for only single set of backup battery .
● RS485 remote control charge , discharge and activation functions .
● It has the function of charge, discharge and activation with muti machine parallel mode by only operating in the display screen of the parallel instrument with parameters as the master. The instrument with parameters as the slave can automatically follow the master’s instructions to distribute power evenly, and start or stop operation.
