Backup power system for PoE switches, 52VDC/2x12Ah/120W, ABS housing IP44 SWBH-120

Backup power system for PoE switches

This is a reliable solution providing uninterrupted power access to your network devices. The SWBH-120 system is designed to work with PoE switches, guaranteeing stable operation even in the event of a mains power failure. The IP44-rated enclosure protects the components from adverse environmental conditions, making it an ideal choice for both indoor and outdoor applications.

The system uses two 12Ah batteries, providing long-lasting backup power. The DC/DC converter boosts the voltage, optimizing operating costs by reducing the number of batteries required. The device is equipped with a range of protections, such as SCP, OLP, OVP and UVP, which protect both connected devices and the power system itself from damage.

The system design has been carefully thought out for easy installation and integration with existing infrastructure. A universal mounting plate allows you to attach a PoE switch with dimensions up to 210x123x38mm. Cable glands of various diameters are also available, making it easy to connect devices and route cables.

Key features and benefits:

• Reliable backup power: Ensures network continuity even during power outages.
• High energy efficiency: The DC/DC converter minimizes energy losses and reduces operating costs.
• Versatility: Compatible with popular PoE switch models on the market (e.g. Pulsar S64WP, SG64WP).
• Solid construction: ABS housing with IP44 rating provides protection against moisture and dust.
• Safety: SCP, OLP, OVP and UVP protections protect devices from damage caused by overload, short circuit or too low voltage.
• Easy installation: Universal mounting plate and cable glands facilitate installation and integration with existing infrastructure.

The input power voltage is 200 - 240 V AC, and the output power is 120 W at 52 V DC and an output current of 2.3 A. The system works with two 12 Ah / 12 V (SLA) batteries and is characterized by an energy efficiency of 87%. It has SCP, OLP, OVP and UVP protections and an IP44 protection class. The external dimensions are 320 x 385 x 130 mm (+/- 2 mm), and the battery compartment dimensions are 215 x 160 x 95 mm (+/- 2 mm).

Using this system guarantees stable network operation in critical situations – an ideal solution for companies and institutions that value the continuity of network infrastructure. The system is particularly recommended for use in video surveillance and anywhere where reliable PoE device power is required.
