Description
The GDBD-A-(10-600V)-30A is a wide-voltage, high-precision intelligent battery discharger designed for 10–600V DC lead-acid battery banks (2V/6V/12V cells). It performs constant-current/constant-power discharge, capacity assessment, and cell imbalance detection via built-in electronic load and real-time data acquisition.
With a 7” TFT touchscreen, ±0.5% voltage accuracy, and ±1% current control precision, it supports standalone operation or PC remote control. The integrated 8GB FLASH stores 1000+ test records, while RS485 enables data transfer and report generation. Rugged, compact, and safe, it’s ideal for substation, UPS, telecom, and industrial battery maintenance.

FAQ
Q: Can it test both 2V and 12V cells in the same bank?
A: Yes. It auto-detects cell voltage (1–16V) and monitors each cell individually.
Q: Is it safe for online testing (battery connected to load)?
A: Yes. It supports online discharge while the battery powers critical loads.
Q: How long can it discharge at 30A continuously?
A: Up to 10 hours (limited by battery capacity and temperature).
Q: Does it come with PC software for reporting?
A: Yes. Free software for data analysis, curve plotting, and professional report generation.
Q: What’s included in the standard package?
A: Main unit, power cable, discharge cables (30A), cell voltage sensors, RS485 cable, USB drive, user manual, rugged carry case.
