HDGC3985 Series Battery Charging&Discharging Tester is mainly used for the charge test of the lead-acid battery of the backup power supply in the telecommunications, mobile, substation, railway transportation and pertrochemical industry power DC industries. It can proceed the discharge and charge for the batteries to extend the lift-time .

1.Various working modes: constant-current discharge, constant-power discharge, constant-current charging, constant-voltage current-limit charging, trickle float charging, etc.
2.7inch 1024*600 LCD screen:Intelligent SCM ARM control, , capacitive touch operation, built in English menu, simple and clear operation menu.
3.Multiple safety protection functions: over-current protection, short-circuit protection, high temperature, reverse polarity and other protection functions.
4.With a number of alarm functions: the use of the process of abnormal problems, such as high voltage, under-voltage, current outside the measurement range, fan failure, etc. can be issued in real time to warn and stop discharging, do not damage the instrument and related testing equipment.
5.Intelligent design of operation: Equipped with quick docking jack, easy to connect, automatic recording and intelligent analysis of the whole test, without manual intervention.
6.Rapid capacity analysis function: the remaining capacity of the battery can be estimated by 3-5 minutes of rapid discharge.
7.Charge/discharge parameter preset function: Built-in a variety of commonly used charge/discharge templates to meet the parameters of different types of batteries, the template data can be saved when the power is turned off, and the test can be started directly on the power supply, without the need for frequent parameter setting.
