Battery 28Ah/12V HPB HPB28-12

Universal battery for security and emergency power systems

The HPB28-12 battery from Pulsar is a reliable power source designed to operate in demanding conditions. It utilizes AGM (Absorbent Glass Mat) technology, which means it is maintenance-free and safe to use – the electrolyte is permanently bound in the separator made of glass mat. This allows the battery to be installed in places with natural ventilation without fear of releasing harmful gases. It is an ideal solution for both professional installers and end-users looking for long-lasting and efficient power.

Construction and operating parameters

The HPB28-12 battery is characterized by a capacity of 28Ah at a voltage of 12V. Its dimensions – 175 x 125 x 166 mm – allow for easy integration with various systems. The recommended charging current is 2.8A, and the maximum is 8.4A. The charging voltage at 25°C is 13.5-13.8V DC for buffer operation and 14.4-14.9V DC for cyclic operation. The battery's lifespan, estimated at 5-8 years at 20°C, guarantees long-term and trouble-free operation.

Applications and benefits

Batteries from the HPB series have been created with professional systems in mind that require reliable backup power. They will be perfect for:

• Fire and alarm systems (compliant with EN54C / HPSG3 standards).
• DSO (Digital Subscriber Line) systems.
• Security systems: CCTV (closed-circuit television), SSWiN (Intrusion and Robbery Alarm System), KD (Access Control).
• UPS (Uninterruptible Power Supply) power supplies – ensuring the continuity of device operation during power outages.
• Industrial automation systems.

Thanks to AGM technology, the battery is completely sealed, eliminating the risk of electrolyte leakage and ensuring safe use. In addition, the lack of maintenance translates into lower operating costs and increased user comfort. The battery is covered by a one-year manufacturer's warranty – Pulsar K. Bogusz Sp. j.
