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 switching power supply module with built-up DC / DC converter with
high energy efficiency, 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 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

2. Installation.
2.1 Requirements.
Device is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and required
for a given country) for ~230 V in and low-voltage installations. The unit should be mounted in confined spaces, in
accordance with the II environmental class, with normal relative humidity (RH=90% maximum, without condensing) and
temperature from -10°C to +40°C.
As power supply is designed for a continuous operation and is not equipped with a power-switch, therefore, an
appropriate overload protection in power supply circuit should be provided. Moreover, user should be informed how to
disconnect power supply unit from mains supply (most frequently through separating and assigning an appropriate fuse in
the fuse-box).
2.2 Installation procedure.
CAUTION!
Before installation, cut off voltage in 230 V power-supply circuit. To switch power off, use an
external switch, in which distance between contacts of all poles in disconnection state is not
less than 3mm.
It is required to install an installation switch with a nominal current of min. 6 A in the power supply
circuits outside the power supply unit.
1. Mount the device in a selected location and connect wires.
2. Remove mounting plate by unscrewing screws, then release plate from hooks (slide up and slightly pull).
3. Connect power cables (~230 V) to L-N clips of the PSU. Connect ground wire to clip marked by earth symbol .
Use a three-core cable (with a yellow and green protection wire) to make connection. Lead cables to
appropriate clips through insulating bushing of PSU.
Shock protection circuit shall be done with a particular care: yellow and green wire coat
of power cable should be connected to terminal marked with the grounding symbol on PSU
enclosure. Operation of PSU without the properly made and fully operational shock protection
circuit is UNACCEPTABLE! It can cause damage to equipment or an electric shock.
4. Connect battery in correct polarity.
5. Make selection is done with use of IBAT jumpers (see: tab.1).
6. Screw switch to mounting plate.
7. Connect switch using cable terminated with a DC 2.1/5.5 plug.
8. Mount inside enclosure.
9. Connect the power 230 V.
10. After installing and checking proper working, enclosure can be closed.
3. Operating status indication.
The power supply unit features LED status indication
3.1 Optical indication.
Moreover, PSU is equipped with LED indicating presence of voltage at PSU output, located on PCB of PSU
module.

4. Maintenance.
Any and all maintenance operations may be performed following the disconnection of PSU module from power
supply network. PSU does not require performing any specific maintenance measures, however, in case of significant
dust rate, its interior is recommended to be cleaned with compressed air. In the case of a fuse replacement, use a
replacement of same parameters.
WEEE MARK
According to the EU WEE Directive –It is required not to dispose of electric or electronic waste as unsorted
municipal waste and to collect such WEEE separately.
CAUTION! Power supply module unit is adapted for a sealed lead-acid battery (SLA). After operation period it must not be
disposed of but recycled according to applicable law.
