PIN FUNCTION / DESCRIPTION
L1 and L2/N (HAM)
An appropriate line filter is required to limit conducted
emissions and ensure reliable operation of the HAM, see
page 8. Connect single phase AC mains to the input of the line
filter via a 10 A, 250 V fuse. Connect the output of the filter to
L1 and L2/N of the HAM. Do not put an X-capacitor across the
input of the HAM or use a line filter with an X-capacitor on its
output as power factor correction may be impacted.
+IN, –IN (HAMD, BAMD)
These pins are connected to the output of the external bridge
rectifier in HAMD / BAMD configurations (Figure 5).
GATE IN (HAM)
The user should not make any connection to this pin.
GATE IN (HAMD)
This pin provides line voltage envelope and phase information
for power factor correction. This connection must be made
through the synchronization diodes between the line filter
and bridge rectifier (Figure 5).

GATE IN (BAMD)
The Gate In pin is an interface pin to the Gate Out pin of a
HAMD or BAMD depending on configuration. The user should
not make any other connection to this pin.
GATE OUT
The Gate Out pin is a synchronization pin for HAMD/BAMD
arrays; the user should not make any other connection to this
pin.
+OUT and -OUT
Connect the +OUT of the HAM to the +IN of the respective
Vicor DC-DC converters with the recommended fuse. Connect
the -OUT of the HAM to the -IN of the converters. In addition,
an external hold-up capacitor of 1,000 µF with a minimum
voltage rating of 450 Vdc, is required (across the output of the
HAM) for 16 ms ride through time at full power (500 µF for half
power, etc). This capacitor must be in close proximity to the
HAM. Do not exceed 3,000 µF of total output capacitance. Lower
values of capacitance may be used for reduced hold up
requirements, but not less than 500 µF. Lower capacitance
values may degrade power factor specifications.
