Power supply 75W 13.8V 5.4A SCP-75-12

Buffered power supply for security and monitoring systems. The Mean Well SCP-75-12 is a reliable device designed to ensure uninterrupted power supply for monitoring, access control, alarm systems and other applications requiring a stable voltage. Its design allows operation with both mains power and a battery – in the event of a mains power failure, it automatically switches to battery power, guaranteeing continuous operation of connected devices. This is an ideal solution for systems where even a short power outage is unacceptable.

Construction and application

The SCP-75-12 features passive cooling (free air circulation), which translates to trouble-free operation and eliminates the need for fan maintenance. The use of high-quality components and testing under full load guarantees long life and stable operating parameters. Additionally, it has a connector for connecting a thermistor, enabling voltage compensation depending on the ambient temperature – which is particularly important in applications exposed to variable temperature conditions. LED indication informs about the correct operation of the device.
