1.1. General description.
Buffer power supply system for PoE switches. SWB-60 is designed for uninterrupted power supply of PoE
switches with 52 V DC. It was designed based on high energy efficiency switching power supply module placed in metal
enclosure (color RAL 9003). DC / DC converter used to increase voltage allows to reduce costs of system by limiting
batteries to 1 pc. Enclosure has a place for 7Ah / 12 V (SLA) battery and is equipped with a tamper switch signaling
opening the door (front panel). Device is equipped with removable universal mounting plate, which allows to mount PoE
switches with dimensions up to 230x110x45 (WxHxD) [mm].
For example Pulsar’s models:
S64, SG64, SFG64, SFG64F1, S108, SG108.
Device can operate in one of two configurations:
1. PoE output power 60 W + 1 A battery charging
2. PoE output power 60 W + 2 A battery charging
