Description
The ADEL System CBI245A is an all-in-one 24V DIN rail DC UPS combining a regulated power supply, intelligent battery charger, backup controller and battery diagnostic system in one compact industrial module. Manufactured in Italy, it is designed for automation, security, telecommunications and infrastructure applications that require dependable 24V DC power.
Operating from a wide single-phase AC input, the CBI245A supplies a 24V DC load at up to 5A, providing 120W of rated output power. During a mains failure, the connected battery supports the load immediately with zero switching time, helping critical equipment remain operational.
ADEL System Battery Care technology provides automatic multi-stage charging, battery diagnostics and protection against deep discharge. The unit supports several industrial battery chemistries and includes relay signalling for mains status, backup operation and battery condition.
ADEL System CBI245A 24V 5A DIN Rail DC UPS
A 120W all-in-one DC UPS with intelligent battery charging, automatic diagnostics and seamless battery backup for industrial 24V systems.
The CBI245A provides continuous 24V DC power for critical loads. Available power is automatically shared between the connected equipment and battery charging, with priority given to the load. If the AC supply fails, the battery supports the output immediately without interruption.
Typical Applications
This 24V DIN rail DC UPS is suitable for applications including:
- Industrial automation and control systems
- Security, access control and fire-detection equipment
- Telecommunications and network infrastructure
- Process control and instrumentation
- Transport and utility installations
- Remote monitoring and signalling systems
All-in-One 24V Backup Power
The unit combines a regulated power supply, battery charger, battery test system and DC UPS controller in a single DIN rail enclosure. It supplies up to 5A continuously from the internal power supply and can deliver additional current for demanding loads when supported by the connected battery.
Battery Care Charging and Diagnostics
ADEL System Battery Care technology manages charging through recovery, boost and float stages. Automatic diagnostics monitor battery connection, polarity and condition, while deep-discharge protection helps preserve battery life during extended backup operation.
Battery Start and Alarm Signalling
The CBI245A supports restart from battery when the mains supply is unavailable. Galvanically isolated relay contacts provide signalling for mains or backup status and for discharged or faulty battery conditions.
Compact DIN Rail Installation
The IP20 enclosure is designed for 35mm DIN rail mounting and uses natural convection cooling without a fan. Its compact industrial construction is suitable for installation inside control panels and equipment cabinets.
Manufactured in Italy
The CBI245A is manufactured in Italy by ADEL System and is designed for professional industrial backup-power applications.
