The Hybrid Power Twin Leaf
product combines the
industry proven AMP
Twin Leaf Card-Edge
connector with high
temperature plastics, high
conductivity metals and a
housing designed for both
pcb or wire connection.
Due to its thin overall profile
and high current density
performance, the Hybrid
Power Twin Leaf connector
was selected for the I/O
connector of the “Thin Power
Supply” section of the Server
Systems Infrastructure (SSI)
standard. This standard
has been adopted through-
out the high-end computer
industry to allow interoper-
ability of subsystems in a
computer server.
The Wire-to-Board version
has been designed to
accommodate up to 300V
AC Input on 18 AWG wire
and offers 24 DC Output
wires (each on 20 AWG)
and 24 Signal wires (each
on 24-28 AWG). The cable-
to-board solution allows
flexibility in routing inputs
and outputs directly to input
filtering devices and to the
point of load for the outputs.
The Hybrid version com-
bines the wire inputs with
traditional printed circuit
board (pcb) solder tail out-
puts all in one connector.
This can be appealing in
some applications where
the input power may not be
suitably located near, or
desired to be integrated
with the output power. The
hybrid version combines a
right angle pcb mount sec-
tion for the DC Signals and
Output Power, along with a
traditional crimp-snap con-
tact for the Input Power.
A key concern with any
power connector is the
temperature rise when the
connector is under load.
These connectors have
been qualified to meet UL
and CSA requirements and
are rated at the industry
standard 30°C T-Rise
criteria. In addition, the
connectors pass the finger
probe test so the connectors
can be energized while
unmated. This is a require-
ment in N + 1 redundant
power supply applications
where power supplies
may be removed, while the
system is still powered.
