Power Shield 8 Battery Monitoring System

Smart BMS for Lead-Acid & Ni-Cd Batteries

80% of UPS failures are due to undetected battery problems. All batteries fail, its just a matter of time. If you’re operating mission-critical systems and relying on the protection of a UPS and battery bank, then it has to make sense to have battery monitoring. It’s about peace of mind – knowing that the batteries are healthy and being constantly monitored. Knowing that everything has been done, that can be done, to protect your enterprise from the consequences of a power failure.

The PowerShield8 system provides monitoring for an unlimited number of batteries, with hardware options targeting both large and small battery systems. A complete solution of hardware and software ensures you get the information you need to confirm your backup batteries are operating within IEEE/IEC guidelines.

The PowerShield8 battery management system combines robust hardware devices for the reliable monitoring and collection of battery data with smart software dashboards. These provide a real-time view of battery health and predictive analytics about future performance. All backed by world-class technical expertise in battery management. That expertise extends across applications in data centers, and critical infrastructure such as transportation, emergency services, utilities and healthcare.

The Brain of your Battery Monitoring System

The Controller is an intelligent hardware device that at four second intervals captures, processes and stores all relevant data collected from batteries and the operating environment.

With regular monitoring comes the accumulation of data, the ability to report and spot trends, and make informed decisions. At the heart of this is the Controller.

The Controller captures, processes and stores data from the Hubs and mSensors. This includes battery voltage (DC and ripple), impedance and temperature, string voltage and current (DC and ripple), humidity, plus ambient temperature.

PowerShield8 meets the needs of a wide range of industries requiring continuous power. From data centers, through to critical infrastructure such as transportation, water services, healthcare and emergency services, etc.

PowerShield customers now have the choice of 2 Controllers:

  • The existing Controller, now called the LX, which has a capacity of up to 512 batteries.
  • The new Controller MX, which has a capacity of up to 200 batteries for smaller battery installations.

Both Controllers have the same battery management functionality. The Controller MX is a cost-effective option for smaller battery installations.
