The UTA240-1H-DM power supply unit from U-tex is a reliable 12V 20A (240W) switching power supply designed for security alarms, video surveillance systems, and LED strip lighting. The unit features a perforated metal casing with a built-in fan, ensuring efficient cooling and stable operation under load. The UTA240-1H-DM model is positioned as a three-channel embedded power supply with terminal connections for easy installation.

Advantages and Purpose

This perforated power supply unit is ideal for long-term continuous operation within security and video surveillance systems. The perforated casing and forced cooling extend the lifespan of the components. A built-in indicator light allows for quick assessment of the power supply's status. Overload and short-circuit protection guarantee the safety of connected equipment.

The UTA240-1H-DM power supply provides a stable 12V voltage with an allowable deviation of ±2%, making it suitable for powering sensitive electronic devices in security and video surveillance systems. The presence of three output channels (+V and -V are split into three branches) allows for simultaneous connection of multiple loads with convenient current and cable distribution. The 9-pin terminal block speeds up installation and connection to the power grid and consumers.

Installation of the power supply is straightforward: connect L, N, and G to the AC mains, then connect consumers to the corresponding +V and -V output terminals. Thanks to the built-in output voltage regulator, the voltage can be finely tuned to compensate for voltage drop across wires under heavy loads. The protection system automatically disconnects or limits the load in emergency situations, increasing equipment safety.

This power supply is particularly useful for installers and mounting organizations who value reliability, ease of connection, and a long service life of the device under continuous operation.
