The HAM must be used in conjunction with a
suitable line filter, such as Vicor’s P/N 07818**,
output holdup capacitor and Vicor DC-DC
converters (see Fig. 9). Connect single phase
AC mains to the input of the line filter via a
standard 10A AC 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. Connect the +Output of the
HAM to the +Input of the converters via a 3A
PC Tron DC fuse. Connect the -Output of the
HAM to the -Input of the converters. Connect
a 1000 µF electrolytic capacitor rated at a
minimum of 450Vdc across the + and -Output
of the HAM (or 500 µF for 300W, etc). This
capacitor must be in close proximity to the
HAM. Connect the Enable Output of the
HAM to the Gate Input of each driver
converter to disable the converters until the
output of the HAM is within normal operating
range. Please refer to Vicor's Applications
Manual for information on the proper
connection of the DC-DC converters.

The aforementioned connections are the
minimum required. In addition, there are
other features available.
• The Auxiliary Supply output is approximately
21V at 3 mA max. This output is usually used
in conjunction with the Power OK signal.
Power OK provides an indication of the
status of the DC output and the AC mains.
• The Enable Output of the HAM must be
connected to the Gate Input of all driver
modules. The HAM will then disable the
module output until the input exceeds 85Vac
and the output has been boosted to 260Vdc.
If an external load is connected directly to
the output of the HAM, do not apply the load
until the output of the HAM is in boost mode.
• Although the efficiency of the HAM is
quite high, it still dissipates significantly
more power than a VI-200 DC-DC converter.
Care should be taken to cool it. Thermal
compound should be used between the
heatsink and baseplate of the VI-HAM,
VI-HAMD and VI-BAMD.

• When making any connections to the
VI-HAM for measurement purposes,
remember that it is not isolated from the
line — either input or output. A line
isolation transformer must be used when
making scope measurements.
• The input voltage range of the VI-HAM is
85 to 264Vac; however it may not start
boosting until the AC mains has exceeded
87Vac. Once the VI-HAM has started, it will
operate down to 85Vac. The VI-HAM
contains 2.5 to 6V of input hysteresis,
therefore if the AC line impedance is high,
i.e., when using a variable autotransformer,
the VI-HAM may start, but the AC line may
then fall enough to drop below undervoltage
lockout. When this happens the AC line will
go up, the HAM starts and the cycle repeats.
Therefore avoid soft AC lines at or near
low line.
