Built-in power supply 300W 12V 25A EPP-300-12

Universal power supply for security and automation systems

The EPP-300-12 power supply is a solid and reliable power source designed for use in monitoring, alarm, building automation systems, and anywhere a stable 12V DC voltage is required. The 300W power allows powering even more demanding devices. The housing design facilitates integration with various installations, and high efficiency translates to energy savings.

Functionality and safety

This switch-mode power supply is characterized by a wide input voltage range (85-264VAC, 120-370VDC), which ensures its versatility and resistance to voltage fluctuations in the network. Built-in protections – against short circuit, overvoltage, overload, and thermal – guarantee safe and long-lasting operation for both powered devices and the installation itself. The active PFC (Power Factor Correction) function improves the quality of the drawn current, minimizing interference in the electrical network.

• Output voltage regulation: The ability to precisely adjust the output voltage in the range of -15% to +10% using an external 1-5.5VDC signal provides full control over the power supply parameters.
• Fan cooling: The built-in fan provides effective heat dissipation, maintaining optimal operating temperature even under heavy load.
• Wide operating temperature range: The power supply maintains full efficiency in the temperature range of -20°C to +65°C, allowing its use in harsh environmental conditions.
• High efficiency: Efficiency at the level of 83.5% (for the 12V version) minimizes energy losses and reduces operating costs.
• Three-year warranty: The long warranty period demonstrates the high quality of the product and provides confidence in reliable operation for many years.

Installation and application

The EPP-300-12 power supply, thanks to its compact dimensions (215x115x50mm), is ideal for mounting inside enclosures and control cabinets. This is a particularly useful solution for installers of security systems, building automation, and all types of devices requiring a stable 12V DC power supply. The ability to program the output voltage makes this power supply a flexible element of every power system.
