Switched-mode buffer power supply, ABS housing IP44, HPSBH 13.8V/3A/7Ah HPSBH-12V3A-B

Buffered switch-mode power supply – reliable power and protection

This buffered switch-mode power supply, in a robust ABS housing with IP44 protection, is the ideal solution for systems requiring uninterrupted power. The device provides a stable 13.8 V DC voltage, essential for the proper operation of various devices such as alarm systems, access control, monitoring or home automation devices. The power supply design allows for the installation of a 7Ah/12V (SLA) battery, which in the event of a mains power failure ensures a smooth switch to battery power.

Functionality and safety in one device

The HPSB-12V3A-B power supply is distinguished by its high efficiency (up to 87%), which translates into energy savings. Built-in protections – short-circuit (SCP), overload (OLP), overvoltage (OVP) and deep discharge (UVP) – guarantee safe and reliable operation. In addition, the housing made of durable ABS (IP44) protects the device from moisture and dust, allowing installation in various environmental conditions. LED optical signaling informs about the operating status of the power supply and battery.

Easy installation and maintenance

The power supply has been designed with the convenience of installers and users in mind. Surface mounting is quick and easy. The housing has openings to facilitate the introduction of cables. The ability to mount a lock further secures the device against unauthorized access. Battery charging and maintenance control ensures its long service life. The battery charging current is 0.5A. The whole is enclosed in a housing with dimensions of 210 x 248 x 95 mm, which allows for easy adaptation to the existing infrastructure. The device is designed to operate at temperatures from -10°C to +40°C.
