Details
The SWB-120 buffer power supply system for PoE switches is designed for uninterruptible power supply of PoE switches with 52 VDC. It is designed based on a switching power supply module with an integrated DC/DC converter with high energy efficiency, housed in a metal enclosure (RAL 9003 color). The use of a DC/DC converter that raises the voltage allows to reduce the cost of operating the system by reducing the number of batteries to 2 pcs. The housing houses two 17 Ah/12 V batteries and is equipped with a microswitch that indicates the opening of the door (headlamp). The device also has a removable universal mounting plate, allowing the installation of PoE switches with maximum dimensions of 230 × 150 × 90 (S × W × G) [mm].
Key features:
- high efficiency (87%)
- battery charging and maintenance control
- built-in DC/DC converter reducing system cost and stabilizing output voltage, regardless of battery charge
- battery over-discharge protection
- battery charging current: 0.5 A
- metal housing in white (RAL 9003)
- demountable universal mounting plate
- START button to start the power supply from the battery
- lightning indication
- short-circuit (SCP), overload (OLP), overvoltage (OVP), tamper protection – protection against opening the housing, against reverse battery connection
