BMS
Wireless battery analysis, monitoring and protection system
The lowest installation and operating cost, maximum performance and battery system life is guaranteed by the voltage equalisation function.
IDEAL FOR
FEATURES
- Total flexibility with 2.4 GHz wireless communication technology that requires no preventative design and allows rack and cabinet configurations to be changed at any time.
- Everything easily under control: the most important parameters of each battery block are measured, including impedance, voltage, current and temperature.
- Good savings due to very simple and fast installation.
- Spikes are prevented and battery life and performance are maximised by equalization functions for each block.
- Each BMS system can monitor and protect up to 750 blocks.
- The batteries are proteced by automatically disabling the measurement if the end-of-discharge voltage is reached. The measurement instruments are re-enabled automatically when the charging current is restored.
- Update frequency of 1 Hz ensures accurate measurements.
- Simultaneous management of batteries of different capacities and types (e.g. VRLA, AGM, NiCd, OPTS, OPZV, etc.) and mixed voltage configurations (e.g. 48 V and 240 V battery systems).
- Colour LCD display to clearly see configurations and parameters, including diagrams and voltage trend plots.
- Programmable alarm level.
- Alarm alerts via email and dry contact.
- Removable SD card for event storage.
- RS-485 ModBus port for communication between the receiver and control panel for monitoring large plants.
- Ethernet port and additional RS-485 ModBus port for remote monitoring.
KEY OPTIONS
- Temperature sensor for each block.
- Sensor kit for use with Ni-Cd batteries.
- Additional antenna for each battery to extend the wireless range.
- Dedicated software for remote monitoring and data storage.
BATTERY VOLTAGE EQUALISER
Continually equalizes the end-of-charge voltage of the batteries to the optimal level in order to prevent overcharging and ensure the best performance and durability. With the equalization function active, the voltage of each battery block is continually kept at the ideal value.

Specifications subject to change without notice – Rev. 22.09
* The maximum transmission distance is estimated to be 50 m if there are no obstacles. A distance of less than 20 m is recommended for optimal performance.
** The optional temperature sensor (TES) is required in order to measure the temperature.
*** The optional Hall-effect current transformer (HCT) is required in order to measure the battery current.
