PULSAR Built-in switched-mode buffer power supply SCP-75-12 13.8V 5.4A

The PULSAR built-in switched-mode buffer power supply SCP-75-12 delivers a regulated 13.8 V DC output with a maximum current of 5.4 A. Engineered as a compact buffer and backup power source for electronic systems, this unit maintains stable voltage for connected devices and switches to battery backup during mains interruptions. The enclosure and mounting design allow integration into control cabinets and equipment racks for security, access control, alarm panels and telecommunications applications.

Advantages

The switched-mode design ensures efficient conversion with low heat dissipation and reliable voltage regulation under varying load conditions. Integrated battery charging and automatic changeover to battery supply on mains failure protect connected equipment from data loss and service interruption. The compact built-in form factor simplifies installation in constrained spaces while delivering consistent output suitable for sensitive electronics.

Suitable for

• Access control systems and door controllers
• Alarm panels and intrusion detection equipment
• Telecommunications and network devices requiring stable 13.8 V backup
• Small automation controllers and monitoring modules
• Any electronic system needing a compact buffer/backup power source

Key specifications

• Output voltage: regulated 13.8 V DC
• Maximum output current: 5.4 A
• Switched-mode (SMPS) topology for efficient power conversion
• Built-in battery charging and automatic mains-to-battery changeover
• Compact enclosure suitable for built-in installation
• Designed for continuous operation with connected batteries for buffering

How to use

Mount the PULSAR SCP-75-12 inside a suitable cabinet or equipment housing following local electrical codes. Connect the mains input and the regulated 13.8 V DC output to your devices, and attach an appropriate rechargeable battery to the battery terminals using correct polarity. On power-up the unit will supply the load and charge the battery; in the event of mains loss it will automatically switch to battery power, maintaining the output voltage within regulation limits.

Usage recommendations

Ensure battery type and capacity match the expected backup time and load current. Verify ventilation around the unit to dissipate heat and avoid mounting near heat sources. Periodically check battery condition and connections to maintain reliable backup operation.
