Description
GDBD-B 110V60A is a professional 110V system dedicated intelligent constant current battery discharge tester designed for capacity verification, routine maintenance and activation of lead-acid battery packs in 110kV substations, power plants, industrial enterprises and UPS systems. It strictly complies with DL/T 724-2000, DL/T 1392-2014 and IEC 60896-2:2008 standards, adopting 20-125V precision voltage design that is optimized for 110V DC power systems, providing higher accuracy and stability than general-purpose wide-voltage testers.
The instrument uses high-precision nickel-chromium alloy resistors as discharge load, featuring low temperature coefficient, no red heat phenomenon and long service life. Its advanced closed-loop constant current control technology ensures stable discharge current with ±1% accuracy throughout the entire discharge process, even as battery voltage drops. The 7-inch high-definition color touch screen provides intuitive operation and real-time display of battery pack voltage, discharge current, elapsed time, discharged capacity and single cell voltage histogram.

FAQ
Q: Why is single cell voltage monitoring important?
A: Single cell voltage monitoring is crucial for identifying weak or degraded cells in a battery pack. A single weak cell can significantly reduce the overall capacity and reliability of the entire battery system. During discharge testing, weak cells will show a much faster voltage drop than normal cells. GDBD-B-110V60A's real-time single cell monitoring and histogram display allow you to quickly identify these weak cells before they cause system failures.
Q: How does the constant current control work?
A: The instrument adopts advanced closed-loop constant current control technology. It continuously monitors the discharge current in real time and automatically adjusts the load resistance to maintain the set current value, even as the battery voltage drops during discharge. This ensures that the discharge rate remains constant throughout the test, providing accurate and reliable capacity measurement results.
Q: Is it safe to discharge batteries with this instrument?
A: Yes. The instrument is equipped with an 8-level comprehensive safety protection system that protects both the battery and the instrument from various abnormal conditions. The nickel-chromium alloy load has no red heat phenomenon and no open flame, eliminating fire hazards. The reverse polarity protection prevents damage caused by incorrect battery connection.
