Individual block temperature option Measured at negative terminal as per IEEE

recommendations Accurate & block specific thermal runaway

detection

At the Battery

750VDC optical isolation at battery Increased safety of personnel & facility Install flexibility & efficiency – consolidate different block & string

voltages [UPS, 48V, genset, emergency lighting] Factory terminated cable sets with no fusing required

Intelligence at the battery Ripple & noise rejection Self-protection Bi-colour LED for fast identification

No more manual battery testing.

Raising the Alarm

Alarms for block voltage, impedance & temperature [thermal runaway]; string voltage & current; ambient temperature

All alarm settings user-editable, but with initial defaults offered

Self-learnt automatic baseline for impedance

All alarm settings are battery & application specific

Detailed, specific alarm information – to individual block level

System intelligence applies appropriate limit set for battery state – Float/Charge/Discharge/Idle

Notification of change of string state

Alarms for internal system diagnostics

In the Control Room

Alarm & data options for data center integration:Ethernet to PowerShield Link software Allows review at all levels – control room, facility managers,

service providers, equipment suppliers. Both life trend and discharge event data presented Battery data stays under your control & ownership

ModbusRTU/TCP or SNMP to local building management system Integrate with existing facility systems Allows implementation of multiple alarm sets

Dry contacts for additional alarm outputs or actionsDedicated serial port for local service & diagnostics

High visibility & ownership of your battery assets.

Notes: What We Measure & Why

Individual block voltage – ensure correct charge and performance under load

Individual block impedance – impedance change gives a solid life trend and end of life assessment.

Ambient temperature at the cabinet/rack – high temperatures kill batteries. A 10°C increase gives a 50% decrease in life expectancy

String current – allows detection of unbalanced strings, and provides rapid understanding of battery activity

String voltage – confirmation of UPS operation & compliance with battery specification

Individual block temperature [optional] – better knowledge of temperature gradients in cabinets; pre-empt thermal runaway
