BM-SM
BTMS String master
| Order code: | BM-SM-xx (xx-see manual) |
|---|---|
| Mounting: | On battery or rail, 3M double sided adhesive tape, DIN rail |
| Dimensions: | 60 × 80 × 30 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)
