Buffered switch-mode power supply for installation Grade 2, PSG2 13.8V/20A PSG2-12V20A

Buffered switch-mode power supply – reliable power for your system

The PSG2 13.8V/20A buffered power supply is a solid solution for providing uninterrupted power to devices requiring a stable 12V DC voltage. It is ideal for alarm systems (SSWiN), access control (KD), video surveillance, and also for intercoms and video intercoms. The device is characterized by high efficiency and a wide range of AC input voltage (200-240V).

Key features and functionality

The PSG2 power supply is designed with safety and reliability in mind. It has built-in protection against short circuit (SCP), overload (OLP), overvoltage (OVP), and deep discharge of the battery (UVP). Additionally, it is equipped with EPS (AC power failure signal) and APS (battery failure signal) relay-type technical outputs, allowing for a quick response in case of power supply problems. The START function allows manual activation of power from the battery, and the automatic battery test every 5 minutes ensures its continuous readiness for operation. The ability to adjust the battery charging current (2A/4A/8A) allows you to adapt the power supply's operation to the specifics of the battery used.

Mounting and compliance with standards

The PSG2 power supply is designed for built-in installation, but it can also be mounted on a DIN rail using an appropriate bracket (DIN4). It meets the requirements of EN50131-6:2017 standard in degree 1 and 2 and EN60839-11-2:2015+AC:2015 standard for access control systems. This ensures that the device meets the highest standards of safety and reliability. The set includes cables for connecting batteries with a cross-section of 6mm².
