BM-SS

BTMS String master

Order code: BM-SS-A1
Mounting: DIN rail, 85 mm
Dimensions: 85 × 120 × 39 mm

Highlights & Features

  • Real-time monitoring of string voltage, charge-discharge current, charge-discharge state and string SOC.
  • Monitor the voltage, impedance, temperature, SOC and SOH of each battery with BM-CS cell sensors and the specially designed isolated power bus.
  • Advanced one-step auto-sensing for individual address. No more manual intervention and setup needed, reducing workload and setup errors.
  • Advanced measurement algorithm, no need to discharge large current and measurement can be lossless.
  • Balancing function: Keep voltage balanced during the floating charge process of battery pack, keeping the individual battery in the best state, extending backup time and life span of battery pack.
  • Communication is based on power-isolated RS485. Secure and stable.
  • Quickly locate the alarmed or faulty battery pack in machine room.
  • External split-core Hall Sensor, measuring charge-discharge current in different ranges.
  • Isolated voltage in communication interface: AC 3750V
  • Supports up to 120 batteries (BM-CS)
