Power supply 155W 54V, 5V, 53.5V ADD-155C

Buffered power supply for security and automation systems

This buffered power supply from Mean Well, model ADD-155C, is a reliable solution providing uninterrupted power in critical applications. The device combines the functions of a stabilized power supply and a battery charger, guaranteeing continuous operation of connected devices even in the event of a mains power failure. It is ideal for alarm systems, access control, video surveillance and other applications requiring high availability.

Construction and application

The ADD-155C power supply is designed to work with lead-acid batteries, which are charged during normal operation from the mains. In the event of a power failure, the device automatically switches to battery power, maintaining a constant output voltage. This design provides protection against data loss and interruptions in the operation of security systems. The ability to adjust the output voltage allows the power supply to be adapted to the specific requirements of different devices.

Key features and benefits

• Two outputs: It has two independent outputs – one stabilized (54V DC) for powering devices and the other (5V DC) for charging the battery.
• Protections: Equipped with a range of protections – against short circuit (SCP), overload (OLP), overvoltage (OVP) and low battery voltage (UVP) – protecting both connected devices and the power supply itself.
• Buffering function: Provides uninterrupted power supply thanks to automatic switching to the battery in the event of a mains power failure.
• Voltage regulation: Allows precise adjustment of the output voltage to the needs of specific devices.
• High efficiency: Characterized by high energy efficiency, which translates into lower operating costs.
• Solid construction: Made of high-quality components, which guarantees long and trouble-free operation.
• Easy installation: Designed for mounting in an enclosure, which facilitates integration with existing systems.

The application of this model is wide - from alarm systems to advanced industrial installations requiring a reliable backup power source. Thanks to this, installers can be sure of the stable operation of the systems entrusted to their care, and end users - the continuity of operation of key devices.
