Qualtech SBMU-70T40M5 Energy-Storage Battery-Box Monitor

Qualtech presents QT-SBMU-70T40M5 as a slave control module installed in an energy-storage battery box. It monitors and reports battery voltage and temperature during charging and discharging and provides under-voltage, over-voltage and temperature alarms. The source states support for up to 70 series cells and separately lists up to 45 temperature-sensing channels. Because the model designation and temperature figure differ, buyers should obtain a confirmed model datasheet and hardware revision before specifying channel counts. Identify battery chemistry, harness segmentation, sensor placement and the master interface; verify alarm response during system commissioning.
