Backup power system for PoE switches, 52VDC/2x17Ah/120W SWB-120

Backup power system for PoE switches – reliable power in every situation

This backup power system, catalog number SWB-120, is designed to provide uninterrupted power to PoE switches operating at 52V DC. It is an ideal solution for installations requiring high availability and resistance to power outages. The device utilizes an efficient switch-mode power supply with a DC/DC converter, resulting in stable and reliable operation. The metal housing (RAL 9003 color) ensures durability and resistance to mechanical damage.

Key features and benefits

The SWB-120 system stands out with its high energy efficiency (87%), which helps reduce operating costs. The built-in DC/DC converter stabilizes the output voltage, regardless of the battery charge level, ensuring optimal operation of connected devices. Battery over-discharge protection and short-circuit, overload, and overvoltage protection guarantee the safety of the installation and connected equipment. Additionally, the housing has a microswitch indicating the opening of the door, which increases the level of security. A removable mounting plate allows for easy installation of a PoE switch with dimensions up to 245x150x90 mm – compatible with Pulsar S64, SG64, SFG64, SFG64F1, S108, SG108 and SF108 models.

Technical specifications and application

The device can operate in two modes: standard and optimized for battery charging. The battery charging current can be set to 0.5A or 2A using a jumper. The system is designed to work with two 17Ah/12V (SLA) batteries. It finds application in video surveillance systems, computer networks, and anywhere where reliable power to PoE devices is required. Thanks to its compact dimensions (330 x 380 x 173 mm) and surface mounting capability, the SWB-120 system is easy to integrate with existing infrastructure. Mounting screws are included to facilitate installation.
