Safety Notes

Each HAM, HAMD or BAMD module must be preceded by a safety

agency recognized fast-blow 10A 3AG fuse.

The HAM is not isolated from the line – either input or output;

a line isolation transformer must be used when making scope

measurements. HAMs do not provide input to output isolation.

Differential probes should be used when probing the input and

output simultaneously to avoid destructive ground loops.

Protective Features

Over Temperature Shut Down

The HAM is designed to shut down when the temperature of

the baseplate exceeds 90°C. Do not operate the HAM above its

maximum operating temperature of 85°C.

Short Circuit Protection

The HAM contains output short circuit protection. Operation

of this function does not clear the input fuse and the output

will resume normal operation after removal of the fault. A short

period of time may be required to allow for cooling of an internal

temperature sensor.

Output Over Voltage Protection

The HAM contains output over voltage protection. In the event

been reduced to zero and the E/O line will be pulled low shutting

down the converters. Beyond this the protection circuit will be

enabled and the output voltage will decrease.

Storage

Vicor products, when not installed in customer units, should be

stored in ESD safe packaging in accordance with ANSI/ESD S20.20,

“Protection of Electrical and Electronic Parts, Assemblies and

Equipment” and should be maintained in a temperature controlled

factory/ warehouse environment not exposed to outside elements

controlled between the temperature ranges of 15°C and 38°C.

Humidity shall not be condensing, no minimum humidity when

stored in an ESD compliant package.

Mechanical Drawing

Note: Mounting a High Boost HAM and Maxi, Mini or Micro DC-DC converter to the same heat sink will require the use of custom length standoffs or a

step in the heat sink mounting surface. This is due to a mechanical stack up difference between the HAM and Maxi, Mini, and Micro converters that leads to

incompatible baseplate height above the PCB.
