Buffered switch-mode power supply for built-in Grade 2, PSG2 13.8V/10A PSG2-12V10A

Reliable power supply for security and access control systems. The PSG2-12V10A buffered power supply from Pulsar is a solid solution for providing uninterrupted power to devices in burglar and assault alarm systems (SSWiN) and access control (KD) systems. The device stabilizes the voltage to 13.8V DC and offers an output current of up to 10A, making it an ideal choice for both simple installations and more complex systems. The power supply design meets the requirements of EN50131-6:2017 and EN60839-11:2013 standards, guaranteeing high reliability and compliance with applicable standards.

Performance and functionality for professionals

The PSG2-12V10A power supply is characterized by high efficiency at 88%, which translates to lower energy losses and more efficient resource utilization. This means the device generates less heat during operation, which affects its stability and lifespan. Built-in protections – against short circuit (SCP), overload (OLP), overvoltage (OVP), and excessive battery discharge (UVP) – protect both the power supply itself and the devices connected to it. Additionally, the START function allows manual switching to battery power if necessary.

User comfort and easy installation

The PSG2-12V10A power supply has intuitive optical signaling using LEDs, informing about the presence of AC voltage, output voltage, and any battery failures. Relay-type technical outputs (EPS – AC power failure, APS – battery failure) are also available, allowing integration with a monitoring or notification system. The compact dimensions of the housing (204 x 141 x 52 mm) allow for easy installation in rack cabinets or alarm system enclosures. The possibility of mounting on a DIN rail (using an appropriate DIN4 bracket) further facilitates installation. The power supply is equipped with a fuse protecting the battery circuit against reverse polarity connection. The battery charging current can be set to 1A or 4A using a jumper. Automatic battery test every 5 minutes ensures its continuous efficiency.
