Befact Technologies Unveils New PoE PD
Thin Type Isolated Embedded PoE SPD Modules
consumer electronics market, Befact
Technologies furthermore launches cost
competitive and high quality embedded SPD
Modules in November, 2009. SPD series
modules support two output voltages － 5.1V
(SPD-50) and 12V (SPD-12). SPD-12 can
deliver up to 12W output power, maximum
DC/DC converting efficiency is 89％ @ full
load. SPD-50 can deliver up to 12W output
power, maximum DC/DC converting efficiency
is 85％ @ full load. The operation
temperature is from -15oC
modules are compliant with IEEE 802.3af
power classification, its isolated and thin
type module. They support PSE Alternative A
and Alternative B connections. SPD modules
are much more “slim” than embedded TPD
series modules －60mm (L) x 16.9mm (W) X16mm
(H), wide range application, low cost
version but high DC/DC converting efficient.
SPD modules are pin to pin compatible with
TPD modules, SPD modules are more convenient
to fit in difference products and
applications that the space is concerned
modules are low cost but high reliability,
specially, in safety protection mechanism.
SPD modules build multi-layer ceramic
capacitor (MLCC) only, long life time
operation and high stability, decrease the
risk of PoE application in both of higher
temperature and lower temperature. For
safety protection mechanism, SPD modules
equip many protections to prevent PD modules
damage to make PoE application more easy and
SPD features as follow:
Support PoE applications in both of Fast
/ Gigabit Ethernet environments.
Support wide input voltage range- 37Vdc
Thermal cut off.
Short circuit protection.
Over current protection.
High DC/DC converting efficiency.
Less external component – one output
Isolation level 1.5KVrms.
Enhanced surge protection.
Internal build in 2 channel bridge
rectifiers support end-point and
Internal build in Thermal Pad－better
