UPS combine DIN rail power and battery management

The CBI series of DIN rail mount DC UPS (uninterruptible power supplies) from Italian manufacturer, Adel Systems offers multiple features for reliable power management in industrial applications.

Addressing the critical need to maintain available power for uninterrupted system operation, these DC-UPS system modules combine DIN rail power and battery management in a single unit.

They can be used in a wide range of demanding applications, including process control, machinery, security or communications.

The DC-UPS system ensures full power is always available to the load.

Multi-stage charging adapts to the battery’s status, so even when close to 0V, the battery can be recharged for a full recovery.

Ensuring availability means that power requirements for the system can be minimised, reducing component count and cost.

The DC-UPS modules intelligently manage the available power between load and battery to protect against outages and deliver uninterrupted operation.

Instead of relying on an external battery to maintain power, the CBI series DIN rail modules charge and maintain batteries for the highest level of availability.  

A power boost mode allows the load current to be 2x the rated output current for continuous operation and 3x the rated current for four seconds. This degree of flexibility is particularly useful when powering highly inductive loads like motors and machinery.

For machine and process control applications, which do not run 24 hours a day, the time buffering feature allows the length of time the systems will run after mains failure to be selected.

The CBI series, unlike most DC-UPS systems has an over-ride system to restart the battery without mains power. This restart is available via RTCONN cable connections or it can be accessed via a pushbutton on the front panel.

Automatic multi-stage charging and real time diagnostics allow fast recharge and recovery of deeply discharged batteries.

The ADELBus communication protocol is based on MODbus-RTU or CANbus. It connects, monitors and controls system parameters locally or via the internet using application tools and cloud-based applications.

Modules in the CBI series can charge any battery chemistry – including open lead acid, sealed lead acid, lead gel, Ni-Cd and Li-Ion - using factory pre-set charging curves.  The CBI modules can be customised to meet specific user and application requirements.

An externally connected sensor automatically adjusts the system charge voltage according to the ambient temperature, to maximise battery life.

By constantly monitoring the batteries to determine its condition in real time, diagnostic battery testing guarantees battery reliability.

Tests include continuously check internal impedance, reverse polarity connection, short circuit, open circuit, disconnected or poor battery connection.

Adel Systems’ DC-UPS modules range from 90 to 305Vac input and 36 to 500 Watts output. They are available now from Relec Electronics.
