Introduction

This evaluation board offers a convenient means to evaluate the performance of 
Vicor’s VTM® current 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 easy PRM-VTM evaluation board 
interconnects, and kelvin voltage measurement test points of all pins of the VTM. 
Please refer to the appropriate VTM datasheet for performance and operating limits, 
available for downloading a

   IMPORTANT NOTICE:

Please read this document before setting up a VTM evaluation board 

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:

n

  Wear approved safety glasses when testing electronic product.

n

  Provide strain relief for wires and secure the board on the test bench to avoid  

 displacement.

n

  Remove 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.

n

  Never 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.
