USER GUIDE UG:014 VI Chip VTM Evaluation Board Contents Page Introduction Introduction 1 This evaluation board offers a convenient means to evaluate the performance of the Vicor VTM current Features 2 multiplier. All evaluation boards include sockets for easy plug-and-play insertion and removal of through-hole components and wires. The board provides lugs for power connections, connectors for Board Description 3 easy PRM-VTM evaluation board interconnects and Kelvin voltage-measurement test points of all pins of the VTM. Please refer to the appropriate VTM data sheet for performance and operating limits, available General Components 4 for downloading at www.vicorpower.com.

This user guide is not comprehensive and the operator should not substitute it for common sense and good practice. The following procedures should be followed during operation: nnWear approved safety glasses when testing electronic product. nnProvide strain relief for wires and secure the board on the test bench to avoid displacement. nnRemove the power and use caution when connecting and disconnecting all test probes and interface lines to avoid unintentional short circuits and contact with hot surfaces. nnNever attempt to disconnect the evaluation board from a PRM evaluation board while power is applied. This system is not designed to demonstrate the hot-plug capability. UG:014 Page 1Contents All VTM evaluation boards arrive with the following contents.
