PRODUCT
DESCRIPTION
The
Astrodyne
ASM
and
BSM
400
Series
are
miniature
open
frame
power
supplies
designed
for
medical
applications.
The
ASM400
is
Class
1
and
BSM400
is
Class
2
with
2
MOPP
(method
of
patient
protection)
isolation
and
BF
leakage
current
and
have
been
certified
by
Underwriters
Laboratories
for
compliance
with
the
latest
edition
of
the
international
medical
safety
standard,
IEC
60601-‐1
3
rd
Edition
using
the
CB
reporting
scheme.
They
are
also
certified
to
be
compliant
with
the
collateral
standard
60601-‐1-‐2
for
EMC
and
bear
the
UL
Recognized
component
marks
for
North
America
and
the
EU
and
the
CE
mark.
These
products
operate
over
the
input
voltage
range
of
90
to
264
VAC
and
50,
60Hz
frequency
and
produce
400
Watts
of
regulated
DC
output
power
in
a
standard
3
x
5
(inch)
form
factor
that
is
1U
height
compatible.
