Buffered switch-mode power supply for built-in Grade 3, PSG3 27.6V/2A/2x17Ah PSG3-24V2A-C

Buffered switch-mode power supply for security systems

This buffered switch-mode power supply, designed for built-in installation, is a reliable solution for alarm and access control systems. It ensures uninterrupted power supply even in the event of a power outage, protecting critical devices from interruptions. Grade 3 classification guarantees a high level of security and compliance with stringent standards.

The power supply is compatible with 2 x 17Ah batteries, providing long-lasting backup operation. The built-in battery charging circuit (0.8A) ensures their proper operation and readiness for use. Additionally, the power supply has protections against overload (OLP), short circuit (SCP), overvoltage (OVP), and undervoltage (UVP), which increases its durability and reliability.

The design of the power supply has been designed for easy installation – both for built-in installation and on a DIN rail (using an appropriate bracket). LED optical signaling informs about the operating status of the device, and OC technical outputs (EPS, PSU, APS) allow integration with the alarm or access control system. The EXT IN input allows connecting external failure sensors.

• Compliance with standards: Meets the requirements of EN50131-6 (degree 1-3) and EN60839-11, which confirms its high quality and reliability in security systems.
• Versatility: Suitable for use in SSWiN and KD systems requiring a stabilized voltage of 27.6V DC.
• High efficiency: Efficiency at 83% minimizes energy losses and reduces operating costs.
• START function: Allows manual switching to battery power if necessary.
• Signaling: LED indicators inform about the status of the power supply and batteries.
• Protections: Protection against overload, short circuit, overvoltage and undervoltage increases the durability of the device and protects connected devices.
• OC outputs: Allow integration with the alarm or access control system by signaling the status of AC power failure, power supply or battery.

This power supply is an ideal solution for both professional security system installers and end-users looking for a reliable power source for their devices. Its solid construction and advanced features ensure long-lasting and trouble-free operation. The dimensions of the device are 200 x 48 x 120 mm (+/-2 mm). The current consumption by the power supply circuits is a maximum of 40mA.
