Finder 78.51.1.230.1203 DIN rail power supply 12V 50W with battery charger function

Finder 78.51.1.230.1203 12V 50W 4.6A DIN rail switching power supply with battery charger function

New high efficiency switching power supply for electrical and electronic applications , with adjustable output voltage and protection against overloads and short circuits. Low profile modular design for DIN rail installation in electrical cabinets. It has a battery charger function to ensure total reliability of the connected systems by connecting a battery in parallel to the output (see application examples in the attached pdf). Input protected by fuse that can be replaced directly from the front panel. Suitable for all DC applications where it is necessary to guarantee a power backup even in the event of a black-out or mains power failure:

• emergency lamps, CCTV systems
• video door entry systems
• pumps, DC motors
• led illumination
• panels for interfacing BUS systems
