Buffered switch-mode power supply Grade 2, HPSG2 13.8V/7A/40Ah HPSG2-12V7A-D

Buffered switch-mode power supply Grade 2 – reliable power supply for security systems

This Grade 2 buffered switch-mode power supply, with an output voltage of 13.8V and an output current of 7A, is designed to provide uninterrupted power to burglary and access control systems (SSWiN and KD). Thanks to its solid construction and compliance with EN50131-6:2017 and EN60839-11:2013 standards, it is a key element ensuring the continuity of security operations. The device is perfect for both professional and home alarm systems.

Construction and functionality

The power supply is enclosed in a durable, metal housing (IP20) adapted for surface mounting. Inside, there is space for a battery with a capacity of up to 40Ah/12V, which provides long-term backup power in the event of a mains power failure. The battery charging current can be adjusted using a jumper – choosing between 1A and 2A, adapting it to the specifics of the battery used. Built-in protections – SCP (short-circuit), OLP (overload), OVP (overvoltage), UVP (deep discharge) and tamper (anti-sabotage) – guarantee safe and reliable operation of the device. Additionally, EPS (AC power failure signal) and APS (battery failure signal) relay-type technical outputs are available, allowing for remote monitoring of the power supply status.

Key features and benefits

• Compliance with standards: Meets the requirements of EN50131-6:2017 and EN60839-11:2013 Grade 2 standards, which confirms its high quality and reliability.
• High efficiency: Efficiency at 87% translates to lower energy losses and lower operating costs.
• Adjustable charging current: The ability to choose the battery charging current (1A/2A) allows for optimization of the charging process and extending the battery life.
• Versatile protections: SCP, OLP, OVP, UVP and tamper protections protect the device and connected systems from damage and unauthorized access.
• Optical signaling: An LED indicates the operating status of the power supply, making it easier to diagnose any problems.
• Easy installation: The housing adapted for surface mounting and the possibility of mounting a lock increase the convenience of installation and use.
• Wide input voltage range: The power supply operates in the range of 200-240V AC, ensuring compatibility with most electrical installations.
• Durable housing: The metal housing provides durability and resistance to mechanical damage.

Remember that proper selection of the power supply parameters to the requirements of a specific system is crucial for its reliable operation. It is worth paying attention to the total current consumption by all devices connected to the power supply and the capacity of the backup battery.
