Primary Control (PC)
The PC can be used to disable the BCM ® module, monitor status, or provide a primary referenced
bias supply.
a.) Connecting PC to the –IN will disable the module.
b.) Connecting a DVM or oscilloscope between PC (positive) and –IN (negative) will
indicate the status of the module. Please note that the PC does not have active current
sinking capability.
c.) Connecting a load between PC (positive) and –IN (negative) will provide a primary
referenced bias supply.
Efficiency Measurement
As the BCM module can deliver and consume large currents, the effect of the PCB must be
considered when making an efficiency measurement. Be certain to accurately measure the
voltage directly at the module using the appropriate pair of contact points located at the
corners of the module.

Thermal Considerations
For most lab environments a fan blowing across the evaluation board and heat sink assembly is
recommended. For more information, see application note AN:008 at vicorpower.com or contact

WARNING: The BCM module and High Voltage BCM Evaluation Board can comfortably
operate at surface temperatures which may pose a thermal hazard to the operator.
Be careful not to touch any exposed surface. Certain BCM modules may operate at
potentially dangerous voltages, use care in such cases. The High Voltage BCM Evaluation
Board is not intended for use in end item equipment.
