Description
The Chinfa DBR60-24 is a compact DIN rail battery charger designed for 24V lead-acid battery systems used in industrial control, automation and DC backup applications. It provides a regulated 27.2VDC charging output at up to 2.5A, with a maximum output power of 68W.
A universal 90 to 264VAC input allows the charger to be used across a wide range of industrial installations without manual input-voltage selection. The DBR60-24 also accepts a high-voltage DC input, making it suitable for applications where either AC or DC source power may be available.
Integrated short-circuit protection, reverse-battery-polarity protection and an internal input filter help protect both the charger and connected battery system. Its compact plastic enclosure mounts directly onto a standard 35mm DIN rail.
Chinfa DBR60-24 24V 2.5A DIN Rail Battery Charger
A compact 68W industrial battery charger for maintaining and charging 24V lead-acid battery systems.
The DBR60-24 converts a universal AC or high-voltage DC input into a regulated 27.2VDC charging output. It is designed for use with 24V lead-acid batteries in industrial backup, control and monitoring systems.
Typical Applications
The Chinfa DBR60-24 is suitable for applications including:
- Industrial DC backup systems
- 24V lead-acid battery charging
- Control-panel standby power
- PLC and automation systems
- Alarm, monitoring and security systems
- Telecommunications and remote equipment
- Emergency power and access-control installations
24V Lead-Acid Battery Charging
The charger provides a nominal 27.2VDC output, suitable for charging and maintaining 24V lead-acid battery banks. Its 2.5A output current supports batteries used in industrial standby and backup-power applications.
Universal Input
The DBR60-24 operates from 90 to 264VAC and can also accept 120 to 375VDC. This wide input range simplifies product selection and allows the same charger to be used across different supply systems.
Integrated Battery Protection
Reverse-battery-polarity protection helps protect the charger if the battery is connected incorrectly. Short-circuit protection is also included to improve reliability under fault conditions.
Compact DIN Rail Installation
The 91 x 90 x 57mm plastic enclosure mounts on a standard 35mm DIN rail and is cooled by natural convection, making the charger suitable for compact industrial control cabinets.
Three-Year Warranty
Chinfa supplies the DBR60-24 with a three-year manufacturer’s warranty for added assurance in professional industrial applications.
