Battery Discharge Load Tester HDFD-2220

General information
HDFD-2220 Battery Discharge Load 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.

● PTC ceramic resistor is adopted to avoid the red heat phenomenon for a safer discharge process .
● 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 set discharge termination condition including cell low voltage,whole group voltage low/high, charge current low, charge/discharge time , charge/discharge capacity ●.When any condition can be met, the instrument can stop automatically testing with buzz sound and record the stop reason at the same time.
● It can evaluate the capacity of discharge test time .
