Grade 2 buffered switch-mode power supply, HPSG2 27.6V/10A/2x17Ah HPSG2-24V10A-C

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

This Grade 2 buffered switch-mode power supply, with a voltage of 27.6V and a current of 10A, is a key element of alarm and access control systems. Designed for uninterrupted power supply of SSwiN and access control devices, it provides stable voltage even in the event of a mains power failure. Construction compliant with EN50131-6:2017 and EN60839-11:2013 standards guarantees a high level of safety and reliability.

Construction and functionality

The power supply is characterized by high efficiency – up to 87% – which translates into energy savings. The ability to select the battery charging current (1A, 2A or 4A) allows adaptation to the specifics of the installation and battery capacity. Equipped with a number of protections – against overload (OLP), short circuit (SCP), overvoltage (OVP) and excessive battery discharge (UVP) – protects both the installation itself and the devices connected to it. Thanks to this, you can be sure that the system will operate stably even in difficult conditions.

Additionally, the power supply has technical outputs indicating AC power failure (EPS) and battery failure (APS), which facilitates diagnostics and quick response in case of problems. Optical LED indication informs about the operating status of the device, and the possibility of connecting an optional LED indicator (PKAZ168) further increases user comfort. The housing is designed for surface mounting.
