The new Voltage Regulation
Module (VRM) family of
connectors is designed to
meet the needs of many
existing and new power
supply standards being
developed. They are dual
row card edge style con-
nectors that are well known
in the computer market.
Currently the connectors
are designed to carry up to
150 amps of DC power —
that’s 300 amps total running
through the connector. The
connector is PCB mounted
and there are versions
available in press-fit or
right-angle. The connectors
have card retention either in
the form of a latch or a metal
retention clip which is added
after the VRM is in place.
Industry Applications
The VRM connector is
controlled by various power
supply standards. Current
ones are EPS-1U, AD2D-
VID, AD2D, VRM 8.5, VRM
9.0, VRM 9.1, VRM 10.0 and
VRM 10.1. Many applica-
tions with a need to transmit
high power from board to
board can benefit from this
connector and additional
customer specific applica-
tions are developing.
