Buffered switch-mode power supply Grade 2, HPSG2 27.6V/5A/2x17Ah HPSG2-24V5A-C

Reliable power supply for security and access control systems

The Pulsar HPSG2-24V5A-C buffered switch-mode power supply is a solid solution for providing uninterrupted power to devices requiring a stable 27.6 V DC voltage. Designed for alarm systems (SSWiN) and access control (KD), as well as video surveillance, it will perform perfectly in any facility where continuity of operation is key. Its construction based on an efficient pulse module, placed in a durable metal housing, guarantees reliability and long life.

Functionality and safety in one device

The HPSG2-24V5A-C power supply offers a range of functions that increase user comfort and installation safety. The output current of 5A allows powering even more demanding devices, and the ability to switch the battery charging current (1A/2A) adapts the operation to the specifics of the connected batteries. Built-in protections – against short circuit, overload, overvoltage and deep battery discharge – protect both the power supply itself and the connected devices. Additionally, the START function allows manual switching to battery power, which is particularly useful during tests or network failures.

Key features and benefits:

• Compliance with standards: Meets the requirements of EN 50131 Grade 2 (SSWiN) and EN 60839-11:2013 Grade 2 (KD) standards, which guarantees its suitability for professional security systems.
• High efficiency: Efficiency at 89% minimizes energy losses and reduces device heating.
• Versatility: The ability to operate in buffered and battery mode ensures continuous power supply even in the event of a power failure.
• Optical signaling: An LED indicates the operating status of the power supply (mains power, battery operation).
• Technical outputs: EPS (AC power failure) and APS (battery failure) outputs allow remote monitoring of the power supply status.
• Tamper-proof housing: A microswitch signals opening of the housing, protecting against unauthorized access.
• Space for two batteries: The housing designed for mounting two 12V 17Ah batteries provides a long backup power time.

Technical specifications:

The power supply operates in the input voltage range of 200-240 V AC and provides an output voltage of 27.6 V DC with a maximum current of 5 A. The ability to adjust the battery charging current allows you to adapt the parameters to specific installation needs. The dimensions of the housing are 330 x 380 x 173 mm (+14 mm distance from the wall for cabling), and the weight is approximately 5.2 kg. The set includes cables for connecting batteries with angled ML062 crimp terminals.
