Power supply 55W 13.8V 4A, 13.4V 0.23A AD-55A

The AD-55A power supply is a reliable power source, ideal for monitoring systems, access control, alarm systems, and all types of devices requiring a stable 13.8V DC power supply. The device is versatile – it can operate as a standard power supply or in buffer mode with a connected battery, ensuring continuous operation in the event of a mains power failure.

The power supply's design is focused on safety and durability. It features built-in protection against short circuits, overloads, and overvoltage, protecting both the installation and connected devices. Additionally, the battery over-discharge protection function extends its lifespan. This gives the installer confidence that the system will operate stably and reliably for a long time.

The AD-55A power supply offers flexibility in terms of output voltage – the CH1 voltage can be adjusted in the range of 12-14.5V DC. The perforated housing provides effective cooling even under heavy load, and clear terminal markings make installation and wiring easier. High efficiency at 71% translates to lower energy losses and lower operating costs.

• Versatility: Operation as a standard power supply or buffer with a battery.
• Safety: Built-in SCP, OLP, OVP and UVP protections protecting the installation and devices.
• Voltage regulation: Ability to adjust the CH1 output voltage to the needs of a specific device (12-14.5V DC).
• Efficient cooling: Perforated housing ensures adequate air circulation.
• High efficiency: 71% efficiency minimizes energy losses and operating costs.
• LED indication: LEDs inform about the operating status of the power supply and the battery level (if connected).

The power supply is characterized by a wide input voltage range (88-264V AC or 124-370V DC), making it compatible with various electrical networks. The battery charging current is 0.23A, which allows for efficient keeping it ready for operation when needed. The device is designed to operate at temperatures from -10°C to +60°C, enabling its use in various environmental conditions. The manufacturer's warranty is 24 months, which confirms the high quality and reliability of the product.
