Recent Job Report #5 – Indramat HVR Power Supply Repair- DIAX04 Series

Today, we have an Indramat HVR02.2-W010N power supply in for repair. After a static check, we connect power to the unit to confirm the fault. It is then disassembled; and taken to our wash-down area for a full cleaning and bake, before we begin the repair. This unit came from a parts manufacturer in Detroit and experienced a voltage spike which burned up incoming line voltage.  The pictorial below follows Adam, an Indramat servo electronics specialist, fully rebuild this back to OEM spec and full run test on Indramat Servo module.
