Solutions for power supply continuity

Adel Systems are based in Italy and are a leading developer and manufacturer of industrial

switchmode power supplies, ‘DC UPS’ and intelligent battery chargers.


DC UPS – CBI Series

The CBI DC UPS combine the functions of a power supply, a back up module and of a battery

charger in one unit. They use switching technology with microcontrollers and optimise the supply

to the DC load either when the AC mains is present or when on battery backup. The CBI units do not

allow for deep discharge of the batteries. The CBI units switch from the mains to the battery in the

event of a mains failure without interruption.

There is automatic protection without fuse against the reserve polarity, short circuit and overload

and overvoltage. They carry out diagnostic checks on the connected battery through the Life Test,

every 90 minutes, enabling the users to select the most appropriate charging curve to maximise the

efficiency of the system and to support a life battery.

They are equipped with two relays; one to operate to indicate the status of the mains or battery

backup and another to indicate any of the eight battery protection functions that the unit monitors.

The primary function of the CBI unit is to optimise the battery condition so when it is required the

battery is as good as its life cycle will allow for. There are options for communication via CANbus

and MODbus on certain modules, and the DYP351 displays allows on the CBI500W and the CBI280

series an option for a door mounted display for battery status updates locally. All units are DIN rail

mounted and there is a range of battery carriers available to safely and easily fit the battery packs

into the enclosure or panel.



The Adel System CB battery chargers are a range of microprocessors controlled chargers. Based on

switch mode technology, they produce an output voltage stabilised at a pre-set value, even when

not charging the battery.


These battery chargers have three charging levels – recovery, boost and trickle charge. All the

chargers have a relay output for a range of battery bank protection functions: replace battery or

flat battery; fault in the main; high voltage at the battery ends; open or sulphated battery; reverse

polarity, short-circuited element and wrong battery voltage. The CB battery charger checks the

battery every 90 minutes. All the modes are automatic and other than selecting the battery type

and charge current level no other set up is required. Communication options of CANbus and MODbus are available on various models.  The CB12245A and CB280122410A are available with dual output voltage 12 or 24 V DC and a stabilised power supply.

Power Supplies for Mains Connection – DFlex & FLEX SERIES


The Adel system offers a truly complete range of industrial power supply units for different

applications. The wide range of input voltages enables them to operate in any part of the world.

The range is available with UL and CSA type-approved, with design based on experience gained

over the years.


The FLEX range of products is characterised from 1, 2 and 3-phase input up to 700W with current

rating ranging to 25A and a power flexibility that reaches 50% of the rated current. They are

characterised by their flexibility of use that allows them to satisfy the most varied applications and

requirements, according to the existing norms. The declared ambient temperature operations field

start from 40 to 60°C.
